primarily in database DBC but also in a number of system databases (for example, Sys_Calendar, TD_SYSFNLIB, SYSUDTLIB, SystemFE, and SYSUIF) that users can retrieve. Tables are reserved for system use and contain metadata about system objects, privileges, events, and usage. Users can retrieve frequently-used data from tables via pre-defined views. The Teradata database administrator determines the set of views available to a user. Installing Data Dictionary The system databases, tables and associated views and macros are created at system initialization (sysinit) time and by executing a set of Dictionary Initialization Program (DIP) scripts. The DIPALL option executes all of the DIP scripts that are installed on every system. Optional DIP scripts include: • DIPACC (supports database access logging) • DIPPDCR (supports infrastructure used by Teradata Professional Services when analyzing system performance issues) Related Topics For information about ... See ... the DIP utility and its executable SQL scripts (such as DIPPDCR, DIPACC, DIPSYSUIF, DIPVIEWS, and DIPALL) Utilities. the macros that are created by the DIPVIEWS script Database Administration. using the DIPACC script to create the DBC.ACCLogRule macro, which is required for setting up database access logging, Security Administration. What the Data Dictionary Stores Information about each database object is stored in the system tables. Data Dictionary 17 Chapter 1: Overview Teradata QueryGrid System tables cannot be directly modified and are used by the system to manage and maintain the integrity of the database. Information in the system tables is used to create, access, modify and execute objects and user data stored in the Teradata Database. The primary system tables include: • Dbase: This table contains information about every database installed on the system. Database information includes names associated with this database (for example, database name, owner name, and account name), timestamps, passwords, and so on. • DataBaseSpace: This table contains space allocation for each database. • TVM and TVFields: This table contains information about every table, view, macro and other objects that are stored in the databases. • Accessrights: This table contains all of the information about user permissions for each type object stored in the database. Teradata database supports the following database objects: • Stored procedures written in SQL and external stored procedures written in C/C++ and Java. • User-defined types (UDTs), user-defined functions (UDFs), and user-defined methods (UDMs). These functions and methods provide you with the toolset to perform whatever type of processing and manipulation of data is required. For detailed descriptions of these objects, see Appendix C: “Database Objects.” Other System Objects For details about system objects not covered in this manual, see Appendix C: “Database Objects.” For information about ... See ... SystemFE database SystemFE Macros. Resource Usage tables Resource Usage Macros and Tables. Sys_Calendar database and DBQL tables Database Administration. Teradata QueryGrid Teradata QueryGrid: Teradata Database-to-Hadoop (also referred to as the Teradata-toHadoop connector) provides a SQL interface for transferring data between Teradata Database and remote Hadoop hosts. For information about related views and tables, see Teradata QueryGrid: Teradata Database-to-Hadoop. 18 Data Dictionary CHAPTER 2 Data Dictionary Views Data Dictionary tables only change in major Teradata releases, but Data Dictionary views can change in minor releases. See DBS Tech Alert 2288 for information about changes to Data Dictionary views in maintenance or efix releases (available from Teradata@Your Service: http:/ /tays.teradata.com/). About Data Dictionary Views During initial system setup, the Database Initialization Program (DIP) creates pre-defined Data Dictionary views, which allow convenient access to data stored in Data Dictionary base tables. For more information about DIP, see Utilities. The DIP script run as part of system setup creates several types of Data Dictionary views with varying purposes. For more information about the Data Dictionary views, see “Types of Views” on page 19. Many Data Dictionary views are accessible by all users by default, but some are restricted. For information about the privileges for Data Dictionary views, see “Access to Data Dictionary Views” on page 23. You can query views using SQL requests. For details, see “Querying Data Dictionary Views” on page 24. Data Dictionary views are used by administrators and by administrative tools, such as Teradata Viewpoint. For more about how Data Dictionary views are used, see “Tracking Resource Usage” on page 26. Types of Views During system installation, the database administrator can load the following views into the DBC user space. Modern Views Because data dictionary tables can change, views provide greater stability. In modern views, object names are returned in the session character set. The substitution character for the session character set will be returned for any characters in the object name that do not exist in the session character set. Modern view names use the following formats: Data Dictionary 19 Chapter 2: Data Dictionary Views Types of Views • view_nameV • view_nameVX For example, All_RI_ChildrenV or All_RI_ChildrenVX, where the “X” denotes a partial view that omits certain restricted data, such as security-related information. Related Topics For more information about ... See ... modern views that end with a suffix “VX” “X Views” on page 21. modern views that end with a suffix “V” “Non-X Views” on page 23. standard language support systems or Japanese language support systems International Character Set Support. the types of privileges “Access to Data Dictionary Views” on page 23. Compatibility Views Compatibility views convert the native variable length Unicode object names into 30 bytes of either Latin or Kanji1.This can cause loss of information by truncation or inability to convert object names longer than 30 characters into Latin or Kanji1. Characters that can not be converted are replaced by the substitution character, which is 0x1A for both Latin and Kanji1. As with all character data, when object names are returned to the user they are converted to the session character set. This conversion can produce loss of information if the characters in the object name cannot be converted to the session character set or exceed the export width for the character data. Compatibility view names use the format: • view_name • view_nameX For example, All_RI_Children or All_RI_ChildrenX, where the X denotes a partial view that omits restricted data, such as security-related information. A modern view exists for every compatibility view in database DBC. The information available in compatibility views is available from the corresponding modern view, and compatibility views should no longer be used to obtain the required information. Note: Teradata strongly encourages you to switch over to modern views. The following compatibility views are deprecated and will be eliminated in a future release. 20 Data Dictionary Chapter 2: Data Dictionary Views Types of Views • • • • • • • • • • • • • • • • • • • • • • • • • • • • DBC.AccessLog[X] DBC.AccLogRules[X] DBC.AccountInfo[X] DBC.AllRights[X] DBC.AllRoleRights[X] DBC.AllSpace[X] DBC.AllTempTables[X] DBC.All_RI_Children[X] DBC.All_RI_Parents[X] DBC.AMPUsage[X] DBC.Association[X] DBC.Authorizations[X] DBC.CharSets[X] DBC.CharTranslations[X] DBC.Children[X] DBC.Collations[X] DBC.Columns[X] DBC.ConnectRules[X] DBC.Databases[X] DBC.Databases2[X] DBC.Database_Default_ Journals[X] DBC.DBCInfo[X] DBC.DBQLRules[X] DBC.DeleteAccessLog[X] DBC.DeleteOldInDoubt[X] DBC.DiskSpace[X] DBC.Events[X] DBC.Events_ Configuration[X] • • • • • • • • • • • • • • • • • • • • • • • • • • • • • DBC.Events_Media[X] • DBC.ExternalSPs[X] DBC.Functions[X] • DBC.HostsInfo[X] DBC.IndexConstraints[X] • • DBC.IndexStats[X] • DBC.Indices[X] • DBC.InDoubtLog[X] • DBC.Journals[X] • DBC.LogOnOff[X] • DBC.LogonRules[X] DBC.MultiColumnStats[X] • • DBC.ProfileInfo[X] • DBC.QryLog[X] DBC.QryLogEventHis[X] • DBC.QryLogEvents[X] • DBC.QryLogExceptions[X] • DBC.QryLogExplain[X] • DBC.QryLogObjects[X] • DBC.QryLogSQL[X] • DBC.QryLogSteps[X] DBC.QryLogSummary[X] • DBC.QryLogTDWM[X] • DBC.QryLogTDWM • Sum[X] • DBC.RCC_Configuration[X] DBC.RCC_Media[X] DBC.RepTables[X] DBC.RestrictedWords[X] DBC.RI_Child_Tables[X] DBC.RI_Distinct_ Children[X] DBC.RI_Distinct_Parents[X] DBC.RI_Parent_Tables[X] DBC.RoleInfo[X] DBC.RoleMembers[X] DBC.SecurityDefaults[X] DBC.SecurityLog[X] DBC.SessionInfo[X] DBC.ShowColChecks[X] DBC.ShowTblChecks[X] DBC.Software_Event_Log[X] DBC.Table_Level Constraints[X] DBC.Tables[X] DBC.Tables2[X] DBC.TableSize[X] DBC.TableText[X] DBC.Triggers[X] DBC.UserGranted Rights[X] DBC.UserRights[X] DBC.UserRoleRights[X] DBC.Users[X] DBC.User_Default_ Journals[X] X Views The modern X views and compatibility X views contain security constraints in their definition to limit the result set to only the rows associated with the requesting user, such as: • Databases • Users • Objects owned or created by the user • Objects on which the user has been granted privileges The following modern X views and compatibility X views also return rows associated with the current role of the user and any nested roles of that current role.

If the current role is. . . Then . . . not NULL or ALL the current role and its nested role are used for security checks. ALL all the role(s) directly granted to the user and all their nested role(s) are used for security checks. The modern X views and compatibility X views run slower than their corresponding non-X versions because the modern X views and compatibility X views have security checks. Compatibility X views are named the same as their corresponding non-X views followed by the character X. 22 Data Dictionary Chapter 2: Data Dictionary Views Access to Data Dictionary Views Modern X views are named the same as their corresponding non-X view followed by the letter V. Non-X Views A non-X view ends with the letter V (for example, DBC_RCC_MediaV). Views that end with the letter V will return every row of every column defined on the underlying table. Access to Data Dictionary Views Default PUBLIC Privileges for Views The system grants the SELECT privilege to PUBLIC on most Data Dictionary views by default. All Teradata Database users have PUBLIC privileges by default. For security and data integrity reasons, the system does not grant INSERT, UPDATE, and DELETE privileges to PUBLIC on Data Dictionary views. You can separately grant these privileges to administrative users if needed. For information on accessing views, see “Querying Data Dictionary Views” on page 24. Views for Which PUBLIC Privileges Are not Granted by Default The system grants default access privileges on some views only to user DBC. These views contain security information or other data that is not for general use, so they are not included when the system grants default PUBLIC privileges on other views. You must GRANT privileges to the following restricted views for any users or roles that need access to them. Data Dictionary • DBC.AccessLog • DBC.AccLogRules • DBC.CSPSessionInfo • DBC.DBQLRules • DBC.DeleteAccessLog • DBC.DeleteOldInDoubt • DBC.InDoubtLog • DBC.LogonRules • DBC.QryLog • DBC.QryLogExceptions • DBC.QryLogExplain • DBC.QryLogEvents • DBC.QryLogObjects • DBC.QryLogSQL • DBC.QryLogSteps 23 Chapter 2: Data Dictionary Views Querying Data Dictionary Views • DBC.QryLogSummary • DBC.QryLogTDWM • DBC.QryLogTDWMSum • DBC.SecurityLog • DBC.Software_Event_Log Compatibility View Privileges Privileges for the compatibility views have been changed to read only and INSERT, UPDATE, DELETE, and SELECT privileges are granted under the following modern views: • CollationsV • CharTranslationsV • HostsInfoV Querying Data Dictionary Views You can submit an SQL request to access the data in a system view and display or print the results. For example: SELECT * FROM DBC.AccLogRules WHERE UserName = ’ALL’; Note: If an SQL request returns a security violation error, a reference to the alternate version of the view name may yield results. If neither version is available, use the HELP statement to inquire about individual objects. If this is not adequate, consult with the Teradata Database administrator. The following sections show various methods for retrieving directory information. For a description of several common administrative uses of the information in Data Dictionary views, see the topics starting with “Tracking Resource Usage” on page 26. How to See All Columns of a View The output of some views extends beyond a standard 80-character width display. To see all the columns, you can either: • Cast the name columns to shorter lengths • Use the SET FOLDLINE and SET SIDETITLES options in BTEQ Querying X Versus Non-X Views The amount of information that can be retrieved from system views at a particular site depends on: • 24 Whether an X version is available for a particular view Data Dictionary Chapter 2: Data Dictionary Views Querying Data Dictionary Views • The privilege granted, if any, on each available view • Whether the statement references “view_name” or “view_nameX” Assuming that both the X and non-X versions of the views are installed, and that the SELECT privilege is granted to PUBLIC on both versions, the information returned by an unconditional SELECT depends on the specified view name, as follows: A view specified as … Returns information about … DBC.viewname all objects for which entries exist in the underlying table. Note: Unconditional SELECTs on non-X views may cause the result to e xhaust the available spool space of the user. DBC.viewnameX only those objects that the requesting user: • • • • owns created has been granted privileges on has access to via current role and the current nested roles of the role Example 1 - Non-X View Query User Test1 queries the Databases view: SELECT DatabaseName, CreatorName, OwnerName, PermSpace FROM DBC.Databases ; As a result, all the databases in the Teradata Database are listed: DatabaseName pers Accounting2 SQLDBA abc123 PERSONNEL Accounting1 Test1 Jane . . CreatorName SYSADMIN Jacobs DBC SYSADMIN SYSADMIN Hillstein SYSADMIN Jane . . OwnerName SYSADMIN Vettes SYSADMIN SYSADMIN SYSADMIN Vettes Test1 Test1 . .

Example 2 - X View Query User Test1 queries the X version of the Databases view: SELECT DatabaseName, CreatorName, OwnerName, PermSpace FROM DBC.DatabasesX ; In contrast to the results of the previous example, only those databases that Test1 owns or has access to are listed: DatabaseName Jane Test1 . . Data Dictionary CreatorName Jane SYSADMIN . . OwnerName Test1 Test1 . . PermSpace 500,000 1,000,000 . . 25 Chapter 2: Data Dictionary Views Tracking Resource Usage Using HELP and COMMENT If the SELECT privilege on one or more system views is revoked or not granted to PUBLIC, you can use the HELP and COMMENT statements to obtain directory information about a particular object for which you have access. HELP does not require long or complex queries and the returns can be formatted for printing. The COMMENT statement returns descriptive information about a database or database object. This includes information about Data Dictionary views. For example, the following COMMENT statement: COMMENT ON DBC.UserGrantedRights; returns the following description: The DBC.UserGrantedRights view provides information on privileges that t he current user has granted to other users. The column names are: Databa seName, TableName, ColumnName, AccessRight, Grantee, Grant Authority, an d Allnessflag. Tracking Resource Usage Information on the usage of the Teradata Database is collected by user and by account number. Control is determined by the definition of each CREATE USER statement. An account is associated with a group of users whose usage charges are maintained by the Teradata Database. Account IDs may be established for a user with the ACCOUNT phrase in the CREATE USER statement. If ACCOUNT is not specified, the default is the account ID of the immediate owner of the user. If the owner has multiple account IDs, then the first account ID is taken for the user as the default. The following sections describe the accounting information available for any Teradata Database session. You can monitor usage with the following Data Dictionary views: • AccountInfo • AllSpace • AMPUsage • DiskSpace • LogOnOff • TableSize The AllSpace, DiskSpace, TableSize, and AMPUsage views are useful in tracking Teradata Database resources for accounting purposes, and in determining how effectively resources are being utilized by accounts and users. 26 Data Dictionary Chapter 2: Data Dictionary Views Tracking Resource Usage AllSpace and TableSize Views You use the AllSpace, Diskspace, and TableSize views that access data from the DatabaseSpace table to show how efficiently a table is distributed across the AMPs on which it is stored. For example, the statement: SELECT CurrentPerm, PeakPerm, AMP FROM DBC.AllSpace WHERE TableName = ’Personnel.Department’; returns a row for each AMP on which the Department table is stored. Data in the CurrentPerm column shows, in bytes, how Department data is distributed across the AMPs. If the distribution is uneven, you can tell from the CurrentPerm data. In addition, the PeakPerm column data indicates any fluctuations in distribution because the table was created. AMPUsage View The AMPUsage view supplies information about AMP CPU time consumed, and the number of AMP to disk read and write operations generated by a given user or account. This view also tracks the activities of any console utilities. A row is returned for each AMP in the system unless aggregate figures are specified. When you ask for resource usage logging, data about CPU overhead, user service, and user execution is collected by vproc type and by node. You can use the AMPUsage, AllSpace, DiskSpace, and TableSize views to summarize resource usage for all AMPs, or for AMPs on which data is stored. Example To obtain a list (in order of the amount of space used) of those databases currently using more than 80% of their permanent space allocation, enter: SELECT DatabaseName, SUM(CurrentPerm) FROM DBC.DiskSpace GROUP BY DatabaseName HAVING (SUM(CurrentPerm)/NULLIFZERO(SUM(MaxPerm))) >.8 ORDER BY SUM(CurrentPerm) DESC; You can also use the AMPUsage and DiskSpace views to compile and maintain usage statistics that can later be selected and analyzed as described in the following sections. Compiling AMPUsage Statistics You can use the AMPUsage view to build and maintain a history table of CPU time and disk I/O statistics for each username/accountname. To create the history table, enter: CREATE TABLE AMPUseHist ( AccountName VARCHAR(30), UserName VARCHAR(30), CPUtime INTEGER, DiskIO INTEGER, Data Dictionary 27 Chapter 2: Data Dictionary Views Tracking Resource Usage Date DATE,Time FLOAT ) PRIMARY INDEX (UserName, AccountName); Periodically, collect usage statistics using this procedure: 1 Select statistics from the AMPUsage view and insert them in the history table. 2 Reset AMPUsage counters to zero for the next collection period. This procedure can be carried out using the BTEQ script: .LOGON username, password INSERT INTO AMPUseHist SELECT AccountName, UserName,SUM(CPUtime), SUM(DiskIO), DATE, TIME FROM DBC.AMPUsage GROUP BY AccountName, UserName, DATE, TIME; UPDATE DBC.AMPUsageV SET CPUTime = 0, DiskIO = 0 ALL; .QUIT The units in which Disk I/O are measured represent data block accesses. CPU time is measured in seconds. Refer to the DiskSpace View to determine how you can use the DiskSpace view to build and maintain a table of disk space usage. After a collection period, you may select AMPUsageV and DiskSpace statistics from the history tables to query the data or to archive the data on a client system. You can use the selected data in sequential data sets on the host computer for subsequent analysis. For example, you can use a BTEQ script to: • Create a client-resident file • Use the BTEQ .EXPORT command to save the data being selected into that file • Select all rows from the DiskSpace history table The following example shows how such a BTEQ job is used to select data from the DiskSpace history table: //JOBNAME JOB jobcard //EXTRACT EXEC PGM=ITBMAIN //STEPLIB DD DSN=TERADATA.APPLOAD,DISP=SHR //SYSPRINT DD SYSOUT=* //SYSABEND DD SYSOUT=* //SAVEDATA DD DSN=ACC.SAVEDATA.DATA,DISP=(NEW,CATLG) // UNIT=SYSDA,SPACE=(TRK,(1,1),RLSE), // DCB=(LRECL=80,RECFM=FB,BLKSIZE=800) //SYSIN DD DATA,DLM=## .LOGON somebody,password .EXPORT DATA DDNAME=SAVEDATA SELECT * FROM DiskSpaceHist ORDER BY Date,Time; .QUIT ## After it is selected and stored, historical data can be used for analysis, as follows: 28 Data Dictionary Chapter 2: Data Dictionary Views Tracking User Activity • Client-resident software packages such as SAS can be used to perform analysis and other statistical manipulation on the data. • Graphic software packages can be used to display the data.

Tracking User Activity The Software_Event_Log view displays, by date and time, any events that have affected processing, such as a memory parity error, a disabling of logons, a Teradata Database restart, or execution of a PM/API SET command, along with an associated message. The processor is identified when appropriate. The LogOnOff view, because it chronologically records all logon and logoff activity as well as the reasons for unsuccessful logons and logoffs, allows you to detect actual and attempted security violations. This view also lets you know how long any user is connected to the Teradata Database. Tracking Logon Rules The LogonRules view is used to review the rules generated by the GRANT LOGON and REVOKE LOGON statements. These statements define which user can log on from what mainframe or LAN host connection, and whether the logon string of the user is acceptable without a password. The initial default is that all users may logon from all hosts, and that every logon string must contain a password. To change the default, use the GRANT LOGON and REVOKE LOGON statements. Tracking Privileges The UserRights view contains information about the privileges that have been granted to any user. See the description of the GRANT statement in SQL Data Control Language, for an explanation of the types of privileges, and how they are granted. If a more detailed audit trail is necessary, this information may be supplemented by log entries that provide an audit trail of the results of checks against requests to access table data. See Security Administration. Data Dictionary 29 Chapter 2: Data Dictionary Views Tracking User Activity Accessing PM/API-Related Data in the Data Dictionary Several Data Dictionary tables log Performance Monitor/Application Programming Interface (PM/API)-related values for some columns. You can use the PM/API information to track the use of MONITOR partition functions. The following DBC tables contain PM/API information: • DBC.AccessRights • DBC.SessionTbl • DBC.SW_Event_Log Note: Execution of the PM/API SET RESOURCE, SET SESSION, and ABORT SESSION requests are considered major system events and are logged to the DBC.SW_Event_Log table. • DBC.Dbase • DBC.TVM The following Data Dictionary views, which are built on those tables, are also carry PM/API-related data: • AllRights • AllSpace[X] • Databases[X] • DiskSpace[X] • Software_Event_Log • LogOnOff • SessionInfo • UserGrantedRights • UserRights The following example queries return information about PM/API-related activities. Example 1 To determine who is using the monitor, enter the following: SELECT UserName, IFPNo FROM DBC.SessionInfo WHERE Partition = ’MONITOR’ ; Example 2 To determine what users have the privilege to force other users off the system, enter the following: SELECT DISTINCT UserName FROM DBC.AllRights WHERE AccessRight = ’AS’ ; The ‘AS’ indicates the ABORT SESSION privilege. 30 Data Dictionary Chapter 2: Data Dictionary Views Using System Views Example 3 To find out what users have been forced off the system (using PM/API ABORT SESSION) in the past two days, enter the following: SELECT DISTINCT UserName FROM DBC.LogOnOff WHERE Event = ’Forced Off’ AND LogDate > DATE - 3 ; Using System Views System Calendar View The Sys_Calendar.Calendar system view helps to extend the properties of a DATE data type column by means of a join. The columns of the view contain data only for the active calendar for the session. The calendar dates range from 1900 to 2100 and are stored in a table in the Sys_Calendar database. The administrator must run DIPCAL SQL and DIPSYSFNC scripts from the DIP utility to create the Sys_Calendar database and the two versions of the Calendar view. There are two versions of the Sys_Calendar.Calendar view. One for the current release, and the version that was provided in the Teradata Database 13.10 release, which is named Sys_Calendar.Calendar_TD1310. The current version (named Sys_Calendar.Calendar_TD_ISO_COMPATIBLE), is an internal view and can only be accessed by user DBC. Release 13.10 Version Note: The Release 13.10 version can only be used for the Teradata system-defined calendar. If you try to use it when the session calendar is ISO or COMPATIBLE, the returned values will not be valid because they will always be from the Teradata calendar. The current version uses embedded services system functions to compute some column values. The Release 13.10 version computes all column values using arithmetic, which generally takes less time than computing values using UDFs. To begin using Release 13.10 version, follow these steps: 1 Use this statement to view the definition of the Release 13.10 version: SHOW VIEW Sys_Calendar.Calendar_TD1310; 2 Use REPLACE to replace the definition of the current version with the definition of the Release 13.10 version. After you redefine the current version, it no longer uses embedded services system functions to compute column values for the following columns: Data Dictionary • day_of_month • weekday_of_month 31 Chapter 2: Data Dictionary Views Using System Views • month_of_quarter • month_of_year • quarter_of_year • year_of_calendar To Revert the View to the Current Version If the view was redefined to the Release 13.10 version and you want to use the current version, you need to redefine it so that is has the definition of the current version. The current version (named Sys_Calendar.Calendar_TD_ISO_COMPATIBLE), is an internal view and has restricted access. Note: The current version can be used with the Teradata, ISO, and COMPATIBLE session calendars. To redefine the Release 13.10 version, follow these steps: 1 Use this statement to view the definition of the Release 13.10 version: SHOW VIEW Sys_Calendar.Calendar_TD_ISO_COMPATIBLE; 2 Use REPLACE to replace the definition of the Release 13.10 version with the definition of the current version. After you redefine the Release 13.10 version, the current version uses Embedded Services functions to compute column values for the following columns: • day_of_month • weekday_of_month • month_of_quarter • month_of_year • quarter_of_year • year_of_calendar Privilege By default, the system grants the SELECT privilege on Sys_Calendar.Calendar to PUBLIC. View Definition This table lists and describes the columns of the view. 32 View Column Name Description Data Type Format calendar_date The default date format. DATE YY/MM/DD day_of_week The day of the week (1-7) where Sunday = 1 and Saturday = 7. INTEGER -(10)9 day_of_month The day of the month (1-31). INTEGER -(10)9 day_of_year The day of the year (1-366). INTEGER -(10)9 Data Dictionary Chapter 2: Data Dictionary Views Using System Views View Column Name Description Data Type Format day_of_calendar The number of days since and including 01/01/1900. INTEGER -(10)9 weekday_of_month The nth occurrence of the weekday in the month (1-5). INTEGER -(10)9 week_of_month The nth full week of the month, first partial week is 0 (0-5). INTEGER -(10)9 week_of_year The nth full week of the year, first partial week is 0 (0-53). INTEGER -(10)9 week_of_calendar The nth full week of the calendar, the first partial week is 0. INTEGER -(10)9 month_of_quarter The month of the quarter (1-3). INTEGER -(10)9 month_of_year The month of the year (1-12). INTEGER -(10)9 month_of_calendar The number of the months since and including 01/01/1900. INTEGER -(10)9 quarter_of_year The quarter of the year. 1 (Jan/Feb/Mar) 4 (Oct/Nov/Dec). INTEGER -(10)9 quarter_of_calendar The number of quarters since and including Q1/1900. INTEGER -(10)9 year_of_calendar The number of calendar years in 4 digit format. INTEGER -(10)9 Example You are encouraged to define views on the Calendar system view because of its convenience. A useful view to define on Calendar is Today: CREATE VIEW Today AS ( SELECT * FROM Sys_Calendar.Calendar WHERE Sys_Calendar.Calendar.calendar_date = DATE ); The Calendar system view permits easy specification of arithmetic expressions and aggregation. This is particularly useful in online analytical processing environments where requests commonly aggregate values by weeks, months, year-to-date, years, and so on. The following is an example. What are the dollar sales for this week, last week, and the same weeks last year for all items in the sportswear department for women? SELECT a2.week_of_calendar, SUM(a1.price) FROM Sales a1, CALENDAR a2, Item a3, Department a4, Today a5 WHERE a1.calendar_date=a2.calendar_date AND (a2.week_of_calendar=a5.week_of_calendar OR a2.week_of_calendar=a5.week_of_calendar - 1 OR a2.week_of_calendar=a5.week_of_calendar - 52 OR a2.week_of_calendar=a5.week_of_calendar - 53 Data Dictionary 33 Chapter 2: Data Dictionary Views Using System Views ) AND a1.itemID=a3.itemID AND a3.classID=a4.classID AND a4.classDesc='Women’s Sportswear' GROUP BY a2.week_of_calendar ORDER BY a2.week_of_calendar; SQLJ System Views The SQLJ database and its views are used by the system to manage JAR files that implement Java external stored procedures. The SQLJ database and its components are created via a DIP script called DIPSQLJ. The DIPSQLJ script is run as part of DIPALL and follows the pattern set by the DBC Data Dictionary initialization process. The DIPSQLJ script revokes all privileges, which could result in modification of SQLJ database views and external stored procedures. The SQLJ database requires sufficient space for all required components to be defined within it, and the initial space allocation for this database is determined based upon that fact. The best practice is to avoid the placement of additional items into this database, as the SQLJ database could be considered an extension to the Teradata Data Dictionary defined in the DBC database. The SQLJ system database contains the views: • JAR_JAR_USAGE • JARS • ROUTINE_JAR_USAGE JAR_JAR_USAGE The JAR_JAR_USAGE view identifies each JAR owned by a given user or database on which other JARs defined on the system are dependent. View Column Name Description Data Type Format DatabaseId The identifier of the database or user in which the JAR identified by JarName is defined. BYTE(4) NOT NULL X(8) JarName The name designator for a JAR that depends on code from another JAR. VARCHAR(128) UNICODE UPPERCASE NOT CASESPECIFIC NOT NULL X(128) 34 Data Dictionary Chapter 2: Data Dictionary Views Using System Views View Column Name Description Data Type Format PathJarName The name designator for a JAR, which is in the SQL-Java path of the JAR identified by JarName. VARCHAR(128) UNICODE UPPERCASE NOT CASESPECIFIC NOT NULL X(128) The SQL-Java path is the search path defined for a particular JAR. With a SQL-Java path defined, a method defined in a particular JAR (JAR A) may invoke a method which is defined in another JAR (JAR B), if JAR B (and all its classes) is contained in the SQL-Java path of JAR A. A SQL-Java path for a JAR can only be created, altered, or dropped via a call to SQLJ.Alter_Java_Path. Corresponding System Tables The corresponding system tables for SQLJ.JAR_JAR_USAGE are: • DBC.JAR_JAR_USAGE • DBC.DBase • DBC.TVM Example The following SELECT statement retrieves information about each JAR owned by a given user or database on which other JARs are dependent. ==> SELECT * FROM sqlj.jar_jar_usage; Result: DatabaseId ---------0000B905 0000B905 JarName ------JAR1 JAR2 PathJarName ----------JAR4 JAR3 JARS The JARS view identifies the installed JARs defined on the system that are accessible to the current user or database. View Column Name Description Data Type Format DatabaseId The identifier of the database or user in which the JAR identified by JarName is defined. BYTE(4) NOT NULL X(8) JarName The name designator for an installed JAR. VARCHAR(128) UNICODE UPPERCASE NOT CASESPECIFIC NOT NULL X(128) JarId The unique identifier for the JAR identified by JarName. BYTE(6) NOT NULL X(12) Data Dictionary 35 Chapter 2: Data Dictionary Views Using System Views Corresponding System Tables The corresponding system tables for SQLJ.JARS are: • DBC.DBase • DBC.JARS Example The following SELECT statement retrieves information about all JAR objects that are accessible to the current user or database. ==> SELECT * FROM sqlj.jars; Result: DatabaseId ---------0000B905 0000B905 0000B905 JarName ------JAR1 JAR2 JAR3 JarId -----------000061280000 000062280000 000063280000 ROUTINE_JAR_USAGE The ROUTINE_JAR_USAGE view identifies the JARs owned by a given user or database on which external Java routines defined on the system are dependent. View Column Name Description Data Type Format DatabaseId The identifier of the database or user in which the JAR identified by JarName is defined. BYTE(4) NOT NULL X(8) RoutineName The name designator for a Java external stored procedure that depends on the JAR identified by JarName. VARCHAR(128) UNICODE UPPERCASE NOT CASESPECIFIC NOT NULL X(128) JarName The name designator for a JAR that contains code that the RoutineName external stored procedure depends on. VARCHAR(128) UNICODE UPPERCASE NOT CASESPECIFIC NOT NULL X(128) Signature The signature defined for Java external stored procedure identified by RoutineName. VARCHAR(6400) LATIN CASESPECIFIC X(255) Corresponding System Tables The corresponding system tables for SQLJ.ROUTINE_JAR_USAGE are: 36 • DBC.ROUTINE_JAR_USAGE • DBC.DBase • DBC.TVM Data Dictionary Chapter 2: Data Dictionary Views Using System Views Example The following SELECT statement retrieves information about all of the JARs owned by a given user or database on which dependent external Java routines are defined. Information about these routines is also returned. ==> SELECT * FROM sqlj.routine_jar_usage; Result: DatabaseId JarName RoutineName Signature DatabaseId JarName RoutineName Signature DatabaseId JarName RoutineName Signature 0000B905 JAR1 MYINT (I[I)V 0000B905 JAR2 MYDEC (Ljava/math/BigDecimal;[Ljava/math/BigDecimal;)V 0000B905 JAR3 MYVARBYTE ([B[Ljava/lang/String;)V User Installed Files View The user installed files (UIF_V) view is created by the SYSUIF database and is populated by the DBC.UIF_INFO table. This view identifies the user installed files (UIFs) defined on the system that are accessible to the current user or database. View Definition This table lists and describes the columns of the view.

Whenever data is not accessed via direct reference, the view cannot be used to update the underlying table. Therefore, you cannot use compatibility views to update object names in the underlying tables. Instead, you must use modern views. Processes that ran on Release 12.0 or earlier may attempt to make updates through the DBC.Collations, DBC.CharTranslations or DBC.HostsInfo views. These views are deprecated and have not been supported since Release 12.0. Teradata strongly recommends that you update such processes to reference the corresponding modern views (for example, CollationsV, CharTranslationsV, and HostsInfoV) instead of the compatibility views. 38 Data Dictionary CHAPTER 3 Views Reference You can use Teradata Studio or Teradata Studio Express to view the Data Dictionary. For information about these tools and to download them, go to: http://developer.teradata.com The following topics describe all the Data Dictionary views in alphabetical order. The columns of each view are listed in the order they appear in the client applications’ Show Definition. DBC.UserDB and DBC.OwnerDB system views are not covered in this manual because they are not usually referenced directly by users. These views are used only to join other system tables and views (especially the X version of views). Data Dictionary tables only change in major Teradata releases, but Data Dictionary views can change in minor releases. See DBS Tech Alert 2288 for information about changes to Data Dictionary views in maintenance or efix releases (available from Teradata@Your Service: http:/ /tays.teradata.com/). Data Dictionary views fall into the following categories: Type Information Stored Operations Internal database operations Database Database instance and owner Schema Database schema (tables, columns, and so on) Integrity Data integrity (constraints and so on) Security Data security (roles, grants, access, and so on) Query Database Query Log Accounting Database usage (accounts, space, and so on) Optimizer Statistics Statistics collected on indexed, non-indexed columns (including row and column PARTITION statistics) and expressions on permanent tables, base and materialized global temporary tables (for the current session) and join and hash indexes. Data Dictionary views consist of one or more columns. Many of the Data Dictionary view columns have referenced table columns. That is, the value in the view column selected corresponds to a value in the column referenced in the table. It would be meaningful to join the view and the referenced table based on the selected column and the referenced column.

the Teradata Database or security administrator has executed one or more BEGIN LOGGING statements. For more information about this security macro, see Security Administration. To install the DBC.AccLogRule security macro, you must manually run the DIP script, DIPACC. For more information about the DIPACC script, see Utilities. Each row in the underlying table defines a rule controlling what privilege check is to be logged when a specific user attempts to access a specific object. 50 Data Dictionary Chapter 3: Views Reference AccLogRulesV When a request is submitted that involves any of the rule criteria, the details of the involvement are recorded in the access log. In AccLogRules, each Access Rule (Acr...) column is named for a particular privilege, which is also associated with an access action and a SQL statement. In each column, each character position represents the frequency with which checks performed on that privilege are to be logged, as follows: 1 2 3 Position 1 (every privilege check) indicates how often to log checks on this privilege when performed against any requests (submitted by a specified user) that attempt to access the specified object. Possible values that could appear in each position are as follows: a B = Both FIRST and LAST occurrences are to be logged. b E = Each occurrence is to be logged. c F = FIRST occurrence is to be logged. d L = LAST occurrence is to be logged. e Blank = No logging. Position 2 indicates how often to log checks on this privilege when performed against requests (submitted by a specified user) that are not allowed to access the specified object (that is, check results are Denials). a B = Both FIRST and LAST occurrences are to be logged. b E = Each occurrence is to be logged. c F = FIRST occurrence is to be logged. d L= LAST occurrence is to be logged. e Blank = No logging. Position 3 (save text of request) indicates whether to record the text of the requests that cause a check on this privilege. a - = Save text only for Denial entries. b + = Save text for all entries. c = Save text for all entries (specified in multiple BEGIN LOGGING statements). d Blank = No WITH TEXT option specified. Example If the following statements are submitted, a SELECT statement retrieving the AccLogRules entries for User1 returns the rows as shown: BEGIN LOGGING ON EACH CREATE TABLE BY Jones ON USER Jones ; BEGIN LOGGING DENIALS WITH TEXT ON FIRST CREATE DATABASE BY Jones ON DATABASE Personnel ; ==> SELECT * FROM DBC.AccLogRules WHERE UserName = ’Jones’ ; Result: Data Dictionary 51 Chapter 3: Views Reference AccountInfoV[X] UserName DatabaseName TVMName Jones Jones All Jones Personnel All CPT CDB CMC CTB CUS E ...

The AllSpace view returns one row of usage information for each AMP in the Teradata Database configuration (or for all AMPs if the SUM aggregate is used). When a database is created, a space row is added to each AMP, with the processor field in each row initialized to 0. The first time the space row is updated (such as when a table is created in the database, or when the system is restarted), the processor field in each row is updated to indicate the actual processor number. When a query applies a SUM aggregate to either the MaxPerm or CurrentPerm column without a WHERE clause, or with a WHERE clause that references only one TableName or DatabaseName, the returned values are double the desired result. For example, the following query, which returns the correct amount of space allocated to Peterson, also returns twice the amount of space currently being used by Peterson (see “DiskSpaceV[X]” on page 122 and “TableSizeV[X]” on page 311). SELECT SUM(MaxPerm), SUM(CurrentPerm) FROM DBC.AllSpace WHERE DatabaseName = ’Peterson’; AccountName Column The AccountName column is the unexpanded default account name for the user or database. A database can only have one account. A user may have a default account plus other accounts. If there is a profile for the user, and it specifies a default account, that account superseded this account name. CurrentPerm Column The CurrentPerm column value includes all AMPs unless a specific AMP is requested. CurrentPersistentSpool Column This column returns the persistent spool space (in bytes) currently used by the database on a specified AMP or on all AMPs if the SUM aggregate is specified. PeakPerm, PeakSpool, PeakPersistentSpool, and PeakTemp Columns You can use the DBC.ClearPeakDisk macro to reset the PeakPerm, PeakSpool, PeakPersistentSpool, and PeakTemp columns. PeakPersistentSpool Column This column returns the integer that represents the maximum persistent spool space (in bytes) that was used at any one time by the database on a specified AMP or on all AMPs if the SUM aggregate is specified. Example The following SELECT statement displays how the space currently used by the data table named Department is distributed on each AMP: Data Dictionary 63 Chapter 3: Views Reference AllTempTablesV[X] ==> SELECT DatabaseName,TableName,AMP,CurrentPerm FROM DBC.AllSpace WHERE TableName=’Department’ ORDER BY 1,2,3 ; Result: DatabaseName -----------Test Test Test Test PERSONNEL PERSONNEL PERSONNEL PERSONNEL User1 User1 User1 User1 TableName ---------DEPARTMENT DEPARTMENT DEPARTMENT DEPARTMENT department department department department department department department department AMP ---1-0 1-1 1-2 1-3 1-0 1-1 1-2 1-3 1-0 1-1 1-2 1-3 CurrentPerm -----------1,024 512 1,024 512 2,048 1,536 1,536 1,536 2,048 1,536 1,536 1,536 AllTempTablesV[X] Category Operations Database DBC View Columns and Referenced Table.Columns View Column Data Type Format Referenced Table.Column HostNo SMALLINT ---,--9 (explicit) TempTables.HostNo (Composite NUPI) --,---,---,--9 (explicit) TempTables.SessionNo (Composite NUPI) X(128) SessionTbl.UserName X(128) Dbase.DatabaseNameI (UPI) NOT NULL SessionNo INTEGER NOT NULL UserName VARCHAR(128) UNICODE NOT CASESPECIFIC NOT NULL B_DatabaseName VARCHAR(128) UNICODE UPPERCASE NOT CASESPECIFIC NOT NULL 64 Data Dictionary Chapter 3: Views Reference AMPUsageV[X] View Column Data Type Format Referenced Table.Column B_TableName VARCHAR(128) X(128) TVM.TVMNameI (Composite UPI) X(12) TempTables.TableId UNICODE UPPERCASE NOT CASESPECIFIC NOT NULL E_TableId BYTE(6) NOT NULL Example After a global temporary table definition is created, you can use the INSERT statement to create a local instance of the global temporary table for use during the session.

Example The following example shows that two user-defined character sets are available for the requesting user: ==> SELECT * FROM DBC.CharSets ; Result: CharSetName French_EBCDIC Swedish_EBCDIC CharTranslationsV Category Operations Database DBC View Columns and Referenced Table.Columns View Column Data Type Format Referenced Table.Column CharSetName VARCHAR(128) X(128) Translation.TranslateName (UPI) ZZ9 (explicit) Translation.TranslateId X(1) Translation.Install UNICODE NOT CASESPECIFIC NOT NULL CharSetId BYTEINT NOT NULL InstallFlag CHAR(1) LATIN UPPERCASE NOT CASESPECIFIC NOT NULL Data Dictionary 79 Chapter 3: Views Reference CharTranslationsV View Column Data Type Format Referenced Table.Column E2I BYTE(256) X(512) Translation.TranslateIn X(512) Translation.TranslateInUp X(512) Translation.TranslateOut X(512) Translation.TranslateOutUp NOT NULL E2IUp BYTE(256) NOT NULL I2E BYTE(256) NOT NULL I2EUp BYTE(256) NOT NULL Usage Notes If client system connections are to use the defined character sets, the Teradata Database system administrator specifies which character set is assigned to which client system (see “HostsInfoV” on page 149). Otherwise, the standard default is used. Also, the user may specify a defined character set after a session is started (see “CharSetsV” on page 78). When specifying a character set for a session, the choice should be compatible with the internal code of the logon client system; that is, an EBCDIC-compatible character set for sessions initiated from an IBM mainframe, ASCII-compatible sets for all others. It is suggested, therefore, that a convention be used for naming character sets which differentiates between EBCDIC and ASCII compatibility (see the example below). CharSetId Column If the character set is user-defined, the ID should also exist in DBC.CharTranslations.CharSetID. For constraints not involving comparison of character data or not using CHARSET_COLL for evaluation, the value is NULL. InstallFlag Column The Teradata Database must be reset to install the rows containing a Y in the InstallFlag field. If the value of InstallFlag is Y in 12 rows or fewer, each Y row is loaded. If InstallFlag is Y in more than 12 rows, then the CharSetName values are sorted in ascending ASCII sequence, and rows are loaded in alphabetical order until 12 sets are installed or the names are exhausted. Example The example below shows that the hexadecimal translation tables for 6 character sets have been defined, and that two of these are flagged for loading. ==> SELECT * FROM DBC.CharTranslations; Result: 80 Data Dictionary Chapter 3: Views Reference ChildrenV[X] CharSetName ---------------German_EBCDIC Italian_EBCDIC Spanish_EBCDIC French_EBCDIC Norwegian_EBCDIC Swedish_EBCDIC Set Id -----100 105 103 104 101 102 Flag ----N N N Y N Y E2I -------------------------00010203A809A97FD1D2D3... 00010203A809A97F2395EE... 00010203A809A97FD1D2D3... 00010203A809A97FD1D2D3... 00010203A809A97FD1D2D3... 00010203A809A97FD1D2D3...

You must reset (initialize) the Teradata Database before the new collation sequence can take effect. When you define a new collation with a name other than ‘MULTINATIONAL,’ set the CollInstall flag to N to avoid extra processing during startup. Example The following statement returns the collation information for all collation sequences defined in the Collations view: SELECT CollName FROM DBC.Collations; The result is the following list: CollName --------------------------KANJI5026_STANDARD KANJIKATA_STANDARD KANJI5035_STANDARD NORWEGIAN_STANDARD SWEDISH_STANDARD Related Topics For more information about the MULTINATIONAL collation sequence, see International Character Set Support.

The DiskSpace view returns one row of usage information for each AMP in the Teradata Database (or for all AMPs if the SUM aggregate is used). When a database is created, a space row is added on each AMP, with the processor field in each row initialized to 0. The first time the space row is updated, such as when a table is created in the database or the system is restarted, the processor field in each row is updated to reflect the actual processor number. You can use the DiskSpace view to build and maintain a table of disk space usage statistics for each username or accountname. To create the history table, enter the following statement: CREATE TABLE DiskSpaceHist ( DataBaseName VARCHAR(30), AccountName VARCHAR(30), MaxPerm FLOAT, MaxSpool FLOAT, CurrentPerm FLOAT, PeakPerm FLOAT, PeakSpool FLOAT, Date DATE, Time FLOAT ) PRIMARY INDEX (DataBaseName, AccountName); Periodically, you can collect usage statistics using the following procedure: 1 Select statistics from the DiskSpace view and insert them in the history table. 2 Reset DiskSpace counters to zero for the next collection period. Note: You can reset the maximum and peak DiskSpace counters to zero using the ClearPeakDisk macro, which is provided on the release tape. This procedure can be carried out using the following BTEQ script: .LOGON username, password INSERT INTO DiskSpaceHist SELECT DataBaseName, AccountName, SUM(MaxPerm), SUM(MaxSpool), SUM(CurrentPerm), SUM(PeakPerm), SUM(PeakSpool), DATE, TIME FROM DBC.DiskSpace GROUP BY DataBaseName, AccountName, DATE, TIME; EXECUTE DBC.ClearPeakDisk; .QUIT AccountName Column The AccountName column is the unexpanded default account name for the user or database. A database can only have one account. A user may have a default account plus other accounts. 124 Data Dictionary Chapter 3: Views Reference DiskSpaceV[X] If there is a profile for the user, and it specifies a default account, that account superseded this account name. CurrentPerm Column The CurrentPerm column value includes all AMPs unless a specific AMP is requested. CurrentPersistentSpool Column This column returns the persistent spool space (in bytes) currently used by the database on a specified AMP or on all AMPs if the SUM aggregate is specified. PeakPerm, PeakSpool, PeakPersistentSpool, and PeakTemp Columns You can use the DBC.ClearPeakDisk macro to reset the PeakPerm, PeakSpool, PeakPersistentSpool, and PeakTemp columns. PeakPersistentSpool Column This column returns the integer that represents the maximum persistent spool space (in bytes) that was used at any one time by the database on a specified AMP or on all AMPs if the SUM aggregate is specified. Example The following SELECT statement displays the permanent disk space across all AMPs: ==> SELECT AMP,DatabaseName,CurrentPerm,MaxPerm FROM DBC.DiskSpace; Result: AMP --. . 0-0 0-0 1-0 1-0 1-0 1-0 . . 1-1 1-1 1-1 1-1 . . 1-2 Data Dictionary DatabaseName -----------. . stst14 ud12 atest a1 btest b2test . . atest a1 btest b2test . . atest CurrentPerm ----------. . 0 0 1,536 0 3,584 49,664 . . 1,536 0 3,584 50,688 . . 1,536 MaxPerm --------. . 125,000 125,000 125,000 247,500 5,000 250,000 . . 125,000 247,500 5,000 250,000 . . 125,000 125 Chapter 3: Views Reference ErrorTblsV[X] ErrorTblsV[X] Category Schema Database DBC View Columns and Referenced Table.Columns View Column Data Type Format Referenced Table.Column ErrTblDbName VARCHAR(128) X(128) Dbase.DatabaseName X(128) TVM.TVMName (NUSI) X(128) Dbase.DatabaseName X(128) TVM.TVMName (NUSI) X(128) Dbase.DatabaseName YYYY-MM-DDBHH:MI:SS ErrorTbls.CreateTimeStamp UNICODE NOT CASESPECIFIC NOT NULL ErrTblName VARCHAR(128) UNICODE NOT CASESPECIFIC NOT NULL BaseTblDbName VARCHAR(128) UNICODE NOT CASESPECIFIC BaseTblName VARCHAR(128) UNICODE NOT CASESPECIFIC CreatorName VARCHAR(128) UNICODE NOT CASESPECIFIC CreateTimeStamp TIMESTAMP(0) NOT NULL The X view references these additional tables: 126 • DBC.AccessRights • DBC.Owner • DBC.RoleGrants • DBC.Roles Data Dictionary Chapter 3: Views Reference Events_ConfigurationV[X] Example The following example shows base data table u2.t1 has an error table u2.ET_t1, which is created by u2: ==> SELECT ErrTblDbName (char(8)), ErrTblName (char(8)), BaseTblDbName (char(8)), BaseTblName (char(8)), CreatorName (char(4)), CreateTimeStamp FROM DBC.ErrorTblsV; Result: ErrTblDbName -----------u2 ErrTblName ---------ET_t1 BaseTblDbName ------------u2 BaseTblName ----------t1 CreatorName ----------u2 CreateTimeStamp ------------------2006-08-28 11:47:56 Events_ConfigurationV[X] Category Operations Database DBC View Columns and Referenced Table.Columns View Column Data Type Format Referenced Table.Column CreateDate DATE YY/MM/DD (explicit) RCEvent.CreateDate 99:99:99.99 (explicit) RCEvent.CreateTime --,---,---,--9 (explicit) RCEvent.EventNum (NUPI) X(30) RCEvent.EventType X(128) RCEvent.UserName NOT NULL CreateTime TIME NOT NULL EventNum INTEGER NOT NULL EventType CHAR(30)LATIN NOT CASESPECIFIC NOT NULL UserName VARCHAR(128) UNICODE NOT CASESPECIFIC NOT NULL Data Dictionary 127 Chapter 3: Views Reference Events_ConfigurationV[X] View Column Data Type Format Referenced Table.Column LogProcessor SMALLINT -(5)9 RCConfiguration.LogProcessor PhyProcessor SMALLINT ZZZZ9 (explicit) RCConfiguration.PhyProcessor Vproc SMALLINT -(5)9 RCConfiguration.Vproc ProcessorState CHAR(1) LATIN X(1) RCConfiguration.ProcessorState ---,--9 (explicit) RCConfiguration.RestartSeqNum NOT CASESPECIFIC NOT NULL RestartSeqNum SMALLINT The X view references these additional tables: • DBC.AccessRights • DBC.DBase • DBC.Owners • DBC.RoleGrants • DBC.Roles Usage Notes The Events_Configuration view contains rows for each archive activity that does not affect all AMPs in the Teradata Database configuration.

Each export width definition has its own rule set. Data Dictionary 135 Chapter 3: Views Reference ExportWidthV An export width rule set is the set of export width conversion multiplier values for all of the fields of the server character sets for a single export width definition. A total of 40 values make up the rule set for one export width definition. Example Export Width Rule Sets This is an example of the rule sets for the pre-defined export width definitions. ExportDefinitionName --------------------EXPECTED MAXIMUM COMPATIBILITY ExportWidthRuleSet ----------------------------1112211111222232222211121111112222322222 1322323221332232322321123111122322323222 1112211111111231111111121111112222322222 What Each Digit Indicates A single digit in an export width rule set indicates two things: • The export width for the server character set. • The export width for the session character set. You can easily identify the export width rules for a server character set. The same 10 digits are always used to indicate the export width rules for the same server character set. • First set of 10 digits LATIN • Second set of 10 digits UNICODE • Third set of 10 digits KANJISJIS • Fourth set of 10 digits GRAPHIC Each of the 10 digits for a server character set are used to indicate the export width rule for the session character set. The same digit (based on the position of the digit) is always used to indicate the export width rule for the same session character set. This table lists the export width rule indicated by each digit in the set of 10 digits used for each server character set. Note: With the exception of the UTF16 session character set export width, the possible values for every digit in an export width rule set are 1, 2, 3, or 4. The possible values for the UTF16 session character set digit are 2 or 4. Digit (by position) Export Width For... 1 • Any session character set that ends in the string _0I • The KATAKANAEBCDIC session character set 2 Any session character set that ends in the string _0U 3 Any session character set that ends in the string _0S 4 The session character set UTF16 Note: The possible values for this digit are 2 or 4 5 136 The session character set UTF8 Data Dictionary Chapter 3: Views Reference ExportWidthV Digit (by position) Export Width For... 6 Any site-defined session character set with STATEMACHINE EUC1211 7 Any site-defined session character set with STATEMACHINE EUC1223 8 Any site-defined session character set with STATEMACHINE S80 9 Any site-defined session character set with STATEMACHINE S80A1E0 10 Any site-defined session character set with STATEMACHINE SOSI0E0F If you know how the ExportWidthRuleSet column values are grouped and the meaning of each of the 10 digits described in this table, you can determine the export width for the current server character set and session character set. This list gives the export width for an export width definition that has this rule set: 1112211111 2222322222 1112111111 2222322222. • • When exporting from the LATIN server character set and the session character set is UTF8, the export width is 2. The digit that represents the export width for this combination of character sets is in the 5th position in the first set of 10 digits in the rule set (the digit in brown). • 5th position digit indicates the UTF8 session character set. • First set of 10 digits indicates the LATIN server character set. When exporting from the KANJISJIS server character set and the session character set is UTF16, the export width is 2. The digit that represents the export width for this combination of character sets is in the 4th position in the third set of 10 digits in the rule set (the digit in blue). • 4th position digit indicates the UTF16 session character set. • Third set of 10 digits indicates the KANJISJIS server character set.

The X view references these additional tables: • DBC.AccessRights • DBC.Owners • DBC.Roles • DBC.RoleGrants Usage Notes One row is returned from the Indices view for each column in each index. Therefore, a query on an index made up of multiple columns returns multiple rows. For information about the possible values for the IndexType column, see Appendix A: “View Column Values.” Some of the column values show information related to a Teradata temporal table or an ANSI temporal table. For more information about these tables, see ANSI Temporal Table Support and Temporal Table Support. IndexDatabaseName Column If the IndexDatabaseName column is a join or hash index, the value is not NULL. Possible Values for the IndexMode Column Note: The Index Number column is NULL if the partitioning is associated with a table or join index that does not have a primary index. 160 Value Description H Secondary index rows are hash distributed to the AMPs. Data Dictionary Chapter 3: Views Reference IndicesV[X] Value Description L Index rows are on the same AMP as the referenced data row. Note: If the index type is a join (J) or hash index (N) index, L is returned. In this instance, L represents an empty value. For information on the IndexType values, see “IndexType Column” on page 358. NULL Primary index Possible Values for the IndexNumber Column Value Description 1 Primary index Multiple of 4 (that is, a number between 4 and 128) Secondary index Possible Values for the SystemDefinedJI Column Value Description Y The TVM row describes a join index defined by the system. Such an index is defined when there are temporal constraints on the underlying base table. NULL Any other objects in the system or a user-defined join index. Possible Values for the TTConstraintType Column Value Description C CURRENT N NONSEQUENCED NULL Used when all rows on a table do not support TRANSACTIONTIME. If the table supports TRANSACTIONTIME, a value of NULL indicates that the row is for an index and not a temporal unique or primary constraint. S SEQUENCED Possible Values for the UniqueOrPK Column Data Dictionary Value Description U Unique 161 Chapter 3: Views Reference IndicesV[X] Value Description K Primary key NULL The unique or primary key constraint is not associated with a time dimension, or the row is not for a unique or primary key constraint description. Possible Values for the VTConstraintType Column Value Description A ANSIQUALIFIER Note: ANSI temporal tables require that the session temporal qualifier for systems using Teradata temporal tables be explicitly set to ANSIQUALIFIER. C CURRENT N NON-SEQUENCED NULL Used when all rows on a table do not support VALIDTIME. If the table supports VALIDTIME, a value of NULL indicates that the row is for an index and not a temporal unique or primary constraint. S SEQUENCED W Unique or primary key constraint defined with WITHOUT OVERLAPS. ANSI valid-time table definitions can include primary key and unique constraints that prevent rows from having valid-time periods that overlap. Example The following SELECT statement displays index information for all the tables in the Personnel database: ==> SELECT TableName,ColumnName,ColumnPosition,IndexType,UniqueFlag FROM DBC.Indices WHERE DatabaseName = ’Personnel’ ORDER BY TableName,ColumnPosition ; The results of this query are as follows: TableName ---------Charges Charges Charges Department Employee Employee Project 162 ColumnName ---------Proj_id EmpNo Proj_id DeptNo EmpNo Name Proj_id ColumnPosition -------------1 1 2 1 1 1 1 IndexType --------S P P P P S P UniqueFlag ---------N N N Y Y N Y Data Dictionary Chapter 3: Views Reference InDoubtLogV InDoubtLogV Category Operations Database DBC View Columns and Referenced Table.Columns View Column Data Type Format Referenced Table.Column LogicalHostId SMALLINT ---,--9 (explicit) InDoubtResLog.LogicalHostId (Composite NUPI) --,---,---,--9 (explicit) InDoubtResLog.SessionNumber (Composite NUPI) X(60) InDoubtResLog.CoordTaskId (Composite NUPI) X(60) InDoubtResLog.RunUnitId (Composite NUPI) X(128) InDoubtResLog.LogonUserName X(128) InDoubtResLog.ResolvingUserLogon Name X(1) InDoubtResLog.CommitOrRollback YY/MM/DD (explicit) InDoubtResLog.UserLogonDate 99:99:99 (explicit) InDoubtResLog.UserLogonTime YY/MM/DD (explicit) InDoubtResLog.CompletionDate NOT NULL SessionNumber INTEGER NOT NULL CoordTaskId VARBYTE(30) NOT NULL RunUnitId VARBYTE(30) NOT NULL LogonUserName VARCHAR(128) UNICODE NOT CASESPECIFIC NOT NULL ResolvingUserLogonName VARCHAR(128) UNICODE NOT CASESPECIFIC NOT NULL CommitOrRollback CHAR(1) LATIN NOT CASESPECIFIC NOT NULL UserLogonDate DATE NOT NULL UserLogonTime TIME NOT NULL CompletionDate DATE NOT NULL Data Dictionary 163 Chapter 3: Views Reference InsertUseCountV[X] View Column Data Type Format Referenced Table.Column CompletionTime TIME 99:99:99 (explicit) InDoubtResLog.CompletionTime X(1) InDoubtResLog.Options NOT NULL Options CHAR(1) LATIN NOT CASESPECIFIC Usage Notes Possible Values for the CommitOrRollback Column Value Description C Committed R Rolled back InsertUseCountV[X] Category Accounting Database DBC View Columns and Referenced Table.Columns View Column Data Type Format Referenced Table.Column DatabaseName VARCHAR(128) X(128) Dbase.DatabaseName X(128) TVM.TVMName X(3) ObjectUsage.UsageType --,---,---,---,---,---,--9 ObjectUsage.UserInsertCnt UNICODE NOT NULL ObjectName VARCHAR(128) UNICODE NOT NULL UsageType CHAR(3) LATIN NOT NULL InsertCount 164 BIGINT Data Dictionary Chapter 3: Views Reference JoinIndicesV Usage Notes Possible Values for the UsageType Column Name Description DML Data Manipulation Language STA Optimizer usage of statistics Example The following SELECT statement shows the number of inserts occurring on a particular object: SELECT InsertCount FROM DBC.InsertUseCountV WHERE DatabaseName = 'Personnel' AND ObjectName = 'Employee'; Result: InsertCount -----------9 JoinIndicesV Category Schema Database DBC View Columns and Referenced Table.Columns View Column Data Type Format Referenced Table.Column DatabaseName VARCHAR(128) X(128) Dbase.DatabaseName X(128) TVM.TVMName (NUSI) UNICODE NOT CASESPECIFIC NOT NULL TableName VARCHAR(128) UNICODE NOT CASESPECIFIC NOT NULL Data Dictionary 165 Chapter 3: Views Reference JournalsV[X] View Column Data Type Format Referenced Table.Column JoinIdxDatabaseName VARCHAR(128) X(128) Dbase.DatabaseName X(128) TVM.TVMName (NUSI) X(1) Indexes.IndexType UNICODE NOT CASESPECIFIC NOT NULL JoinIdxName VARCHAR(128) UNICODE NOT CASESPECIFIC NOT NULL IndexType CHAR(1) LATIN UPPERCASE NOT CASESPECIFIC NOT NULL Usage Notes For information about the possible values for the IndexType column, see Appendix A: “View Column Values.” Example The following SELECT statement displays the join indexes defined on the table user1.oneoneone: ==> SELECT joinidxdatabasename, joinidxname FROM joinindicesv WHERE databasename = 'user1' and tablename = 'oneoneone'; Result: JoinIdxDataBaseName ------------------user1 JoinIdxName -----------ji JournalsV[X] Category Schema Database DBC 166 Data Dictionary Chapter 3: Views Reference JournalsV[X] View Columns and Referenced Table.Columns View Column Data Type Format Referenced Table.Column Tables_DB VARCHAR(128) X(128) Dbase.DatabaseName X(128) TVM.TVMName (NUSI) X(128) Dbase.DatabaseName X(128) TVM.TVMName (NUSI) UNICODE NOT CASESPECIFIC NOT NULL TableName VARCHAR(128) UNICODE NOT CASESPECIFIC NOT NULL Journals_DB VARCHAR(128) UNICODE NOT CASESPECIFIC NOT NULL JournalName VARCHAR(128) UNICODE NOT CASESPECIFIC NOT NULL The X view references these additional tables: • DBC.AccessRights • DBC.Owners • DBC.RoleGrants • DBC.Roles Example The statement on the following screen selects information from the Journals view for the table named PriceA: ==> SELECT TableName,Tables_DB,Journals_DB,JournalName FROM DBC.Journals WHERE Tablename = 'PriceA' ; Result: TableName --------PriceA . . .

Possible Values for UnityProxyLogon The UnityProxyLogon column indicates if a TD2 logon without a password has occurred. Unity Director can log on a TD2 session using the PROXY mechanism on a managed database system, after the same user has successfully been logged on to another managed database system. Value Description T True indicates the TD2 session logged onto a managed database from Unity Director with no password after the user successfully logged onto another managed database. F False indicates the TD2 session logged on or attempted to log on with a password. Unity_AuthUser Column The referenced table column for Unity_AuthUser (DBC.EventLog.RFU3) is used to provide the audit trail information for the security policy.

Examples This section contains examples of the use of this view to retrieve information about objects that have different types of partitioning and different levels of partitioning. For each example, this information is provided: • A brief description. • A query that could be used to retrieve the information. Example 1: Partitioned Objects The PartitioningConstraintsV view is used to retrieve a list of partitioned objects, regardless of the type of partitioning. This query could be used to retrieve this information. It does not contain any clauses to specify the type of partitioning. SELECT DatabaseName, TableName (TITLE 'Table/Join Index Name') FROM DBC.PartitioningConstraintsV ORDER BY DatabaseName, TableName; Example 2: Objects with Column Partitioning The PartitioningConstraintsV view is used to retrieve a list of objects that have column partitioning. This query could be used to retrieve this information. It is very similar to the query used in “Example 1: Partitioned Objects,” but it contains a WHERE clause that specifies the type of partitioning. SELECT DatabaseName, TableName (TITLE 'Table/Join Index Name') FROM DBC.PartitioningConstraintsV WHERE ColumnPartitioningLevel >= 1 ORDER BY DatabaseName, TableName; Example 3: Objects with 8-byte Multilevel Partitioning The PartitioningConstraintsV view is used to retrieve a list of object that: Data Dictionary • Have 8-byte, multilevel partitioning, and • One of the levels is column parititioning. 187 Chapter 3: Views Reference PeriodsV[X] This query could be used to retrieve this information. SELECT DatabaseName, TableName (TITLE 'Table/Join Index Name') FROM DBC.PartitioningConstraintsV WHERE MaxCombinedPartitions >= 65536 AND PartitioningLevels >= 2 AND ColumnPartitioningLevel >= 1 ORDER BY DatabaseName, TableName; Example 4: Objects with 2-byte Single Level Column Partitioning The PartitioningConstraintsV view is used to retrieve a list of objects that: • Have 2-byte, single-level partitioning, and • The type of partitioning is column parititioning. This query could be used to retrieve this information. SELECT DatabaseName, TableName (TITLE 'Table/Join Index Name') FROM DBC.PartitioningConstraintsV WHERE MaxCombinedPartitions <= 65535 AND PartitioningLevels = 1 AND ColumnPartitioningLevel = 1 ORDER BY DatabaseName, TableName; Related Topics For more information about column partitioning levels, see SQL Data Types and Literals.

START_COLUMN_NAME Column The START_COLUMN_NAME column is the name of the column that will store the start column name of the valid-time derived period column, system-time derived period column, or nontemporal derived period column. END_COLUMN_NAME Column The END_COLUMN_NAME is the name of the column that will store the end column name of the valid-time derived period column, system-time derived period column, or nontemporal derived period column.

Then we do a SORT to order Spool 2 by row hash. The size of Spool 2 is estimated with low confidence to be 10 rows. The estimated time for this step is 1 hour and 1 minute. 2) We do an all-AMPs RETRIEVE step from DBC.SessionTbl by way of an all-rows scan with no residual conditions into Spool 4 (all_amps), which is redistributed by hash code to all AMPs. Then we do a SORT to order Spool 4 by the sort key in spool field1 eliminating duplicate rows. The size of Spool 4 is estimated with low confidence to be 2 rows. The estimated time for this step is 1 hour and 1 minute. 5) We do an all-AMPs RETRIEVE step from Spool 4 (Last Use) by way of an all-rows scan into Spool 3 (all_amps), which is duplicated on all AMPs. Then we do a SORT to order Spool 3 by row hash. The size of Spool 3 is estimated with no confidence to be 4 rows. 6) We execute the following steps in parallel. 1) We do an all-AMPs JOIN step from Spool 2 (Last Use) by way of an all-rows scan, which is joined to Spool 3 (Last Use) by way of an all-rows scan. Spool 2 and Spool 3 are joined using an exclusion merge join, with a join 204 Data Dictionary Chapter 3: Views Reference QryLogObjectsV condition of ("DatabaseName = UserName"). The result goes into Spool 5 (all_amps), which is duplicated on all AMPs. The size of Spool 5 is estimated with index join confidence to be20 rows. The estimated time for this step is 1 hour and 1 minute. 2) We do an all-AMPs RETRIEVE step from DBC.DBSpace by way of an all-rows scan into Spool 6 (all_amps), which is built locally on the AMPs. The size of Spool 6 is estimated with low confidence to be 134 rows. The estimated time for this step is 1 hour and 1 minute. 7) We do an all-AMPs JOIN step from Spool 5 (Last Use) by way of an allrows scan, which is joined to Spool 6 (Last Use) by way of an all-rows scan. Spool 5 and Spool 6 are joined using a single partition hash join, with a join condition of ("DatabaseId = DatabaseId"). The result goes into Spool 1 (group_amps), which is built locally on the AMPs. Then we do a SORT to order Spool 1 by the sort key in spool field1. The size of Spool 1 is estimated with index join confidence to be 134 rows. The estimated time for this step is 1 hour and 1 minute. 8) Finally, we send out an END TRANSACTION step to all AMPs involved in processing the request. -> The contents of Spool 1 are sent back to the user as the result of statement 1. The total estimated time is 1 hour and 1 minute. Note: The ExplainText does not contain any format. It is just one long string. The example was manually edited to add the line breaks to make it easier to read.

For each index, there is a database name, table name, and column name. The ObjectId column is the identifier of the table and the ObjectNum column is the number of the index in that table. For multi-column indexes, there is one row for each column of the index that a query used. For example, if an index consists of three columns and the query uses all three, there will be three rows, each with a different column name. The column name will be null for an index for statements such as COLLECT STATISTICS, ALTER PROCEDURE, SHOW PROCEDURE, or SELECT COUNT(*). JIx Join index. For each join index, there is a database name and join index name in the ObjectTableName field. For these rows, the ColumnName indicates a column referred to by the join index. • ObjectType is ‘JIx.’ • ObjectId matches the ID of the join index. • ObjectNum is 0.

ServerByteCount Note: This column is also documented in the QueryGrid manuals. PersistentSpool Usage Notes If step information of the query is requested, a step table is populated with a row for each step . CPUTimeNorm Column The CPUTimeNorm calculation is made for each PE in the system. It is used for systems with processors where each node may have CPUs with different scaling factors. Data Dictionary 217 Chapter 3: Views Reference QryLogStepsV FragmentNum Column This column is NULL for static plans only. LockDelay Column The maximum wait time to get a lock on an object in centiseconds. The maximum value is 32,767 centiseconds. NumContexts Column If no contexts are allocated, the value of the NumContexts column is NULL. NumCPReferences Column If there are no column partitioning, the value of the NumCPReferences column is NULL. RowCount Column If the row count for a step is 18,446,744,073,709,551,615, the number is logged in the RowCo unt column as 1.8446744073709552e+19. Note: The value formatted as a decimal value is 18,446,744,073,709,551,616 due to float arith metic. ServerByteCount The ServerByteCount column is the total number of bytes sent to or received from a foreign server for each step. Possible Values for the NumCombinedPartitions Column The value of the NumCombinedPartitions column is non-zero only if: • There is static partition elimination for the step (for a query submitted to a Teradata Databa se 14.0 or later). • A source table has column partitions. Otherwise, the NumCombinedPartitions column is NULL. Possible Values for the TriggerKind Column • BegLoop • FetchQualRows • BldUsingRow • GetActvCnt • IdColWithRowTrig • SkipQualRows • EndLoop Example The following SELECT statement retrieves all rows that match the query ID 30719092576202 3013 from the QryLogStepsV view: 218 Data Dictionary Chapter 3: Views Reference QryLogStepsV select * from qrylogstepsv where queryid = 307190925762023013; The query returns the following result: ProcID CollectTimeStamp QueryID StepLev1Num StepLev2Num StepName StepStartTime StepStopTime ElapsedTime EstProcTime EstCPUCost CPUTime IOcount EstRowCount EstRowCountSkew EstRowCountSkewMatch RowCount RowCount2 RowCount3 NumOfActiveAMPs MaxAmpCPUTime MaxCPUAmpNumber MinAmpCPUTime MaxAmpIO MaxIOAmpNumber MinAmpIO SpoolUsage MaxAMPSpool MaxSpoolAmpNumber MinAMPSpool StepWD LSN UtilityTableID RowsWComprColumns EstIOCost EstNetCost EstHRCost CPUtimeNorm MaxAmpCPUTimeNorm MaxCPUAmpNumberNorm MinAmpCPUTimeNorm NumCombinedPartitions NumContexts NumCPReferences StepInstance StepStatus DispatchSeq StatementNum TriggerNestLevel TriggerKind FragmentNum IOKB VHLogicalIO VHPhysIO VHLogicalIOKB Data Dictionary 30719 2014-03-13 07:21:39 307190925762023013 1 0 MLK 2014-03-13 07:21:35.090000 2014-03-13 07:21:35.090000 0:00:00.000000 0.000 0.000 0.008 0 0 0 0 4 0 ? 4 0.004 2 0.000 0 ? 0 0 0 ? 0 ? ? ? 0 0.000 0.000 0.000 0.538 0.269 2 0.000 ? ? ? 1 AMPokay 1 1 0 ? ? 0.000 0.000 0.000 0.000 219 Chapter 3: Views Reference QryLogSummaryV VHPhysIOKB PhysIO PhysIOKB LockDelay SSRReceiverCount DMLLoadID ServerByteCount PersistentSpool 0.000 0.000 0.000 ? ? ? ? 0 QryLogSummaryV Category Query Database DBC View Columns and Referenced Table.Columns View Column Data Type Format Referenced Table.Column ProcID DECIMAL(5,0) -(5)9 (explicit) DBQLSummaryTbl.ProcID (Composite NUPI) YYYY-MMDDBHH:MI:SS DBQLSummaryTbl.CollectTimeStamp (Composite NUPI) NOT NULL CollectTimeStamp TIMESTAMP(6) NOT NULL UserID BYTE(4) X(8) DBQLSummaryTbl.UserID AcctString VARCHAR(128) X(128) DBQLSummaryTbl.AcctString UNICODE NOT CASESPECIFIC LogicalHostID SMALLINT ZZZ9 (explicit) DBQLSummaryTbl.LogicalHostID AppID CHAR(30) X(30) DBQLSummaryTbl.AppID X(30) DBQLSummaryTbl.ClientID X(45) DBQLSummaryTbl.ClientAddr X(8) DBQLSummaryTbl.ProfileID UNICODE NOT CASESPECIFIC ClientID CHAR(30) UNICODE NOT CASESPECIFIC ClientAddr CHAR(45) LATIN NOT CASESPECIFIC ProfileID 220 BYTE(4) Data Dictionary Chapter 3: Views Reference QryLogSummaryV View Column Data Type Format Referenced Table.Column SessionID INTEGER --,---,---,--9 (explicit) DBQLSummaryTbl.SessionID --,---,---,--9 (explicit) DBQLSummaryTbl.QueryCount X(1) DBQLSummaryTbl.ValueType ----,---,---,---,--9.999 (explicit) DBQLSummaryTbl.QuerySeconds ZZZ,ZZZ,999 (explicit) DBQLSummaryTbl.QuerySeconds, NOT NULL QueryCount INTEGER NOT NULL ValueType CHAR(1) LATIN NOT CASESPECIFIC QuerySeconds FLOAT NOT NULL AverageTime FLOAT DBQLSummaryTbl.QueryCount TotalIOCount FLOAT ----,---,---,---,--9 (explicit) DBQLSummaryTbl.TotalIOCount AverageIO FLOAT Z(10) DBQLSummaryTbl.TotalIOCount, DBQLSummaryTbl.QueryCount AMPCPUTime FLOAT ZZZ,ZZZ.999 (explicit) DBQLSummaryTbl.AMPCPUTime AverageAmpCPU FLOAT ZZZ,ZZZ.999 (explicit) DBQLSummaryTbl.AMPCPUTime, ZZZ,ZZZ.999 DBQLSummaryTbl.ParserCPUTime ParserCPUTime FLOAT DBQLSummaryTbl.QueryCount (explicit) AverageParserCPU FLOAT ZZZ,ZZZ.999 DBQLSummaryTbl.ParserCPUTime, (explicit) DBQLSummaryTbl.QueryCount AMPCPUTimeNorm FLOAT ZZZ,ZZZ.999 (explicit) DBQLSummaryTbl.AMPCPUTimeNorm AverageAmpCPUNorm FLOAT ZZZ,ZZZ.999 (explicit) DBQLSummaryTbl.AMPCPUTimeNorm, DBQLSummaryTbl.QueryCount ParserCPUTimeNorm FLOAT ZZZ,ZZZ.999 (explicit) DBQLSummaryTbl.ParserCPUTimeNorm AverageParserCPU Norm FLOAT ZZZ,ZZZ.999 DBQLSummaryTbl.ParserCPUTimeNorm, (explicit) DBQLSummaryTbl.QueryCount LowHist FLOAT ----,---,---,---,--9.999 (explicit) DBQLSummaryTbl.LowHist ----,---,---,---,--9.999 (explicit) DBQLSummaryTbl.HighHist NOT NULL HighHist FLOAT NOT NULL Data Dictionary 221 Chapter 3: Views Reference QryLogTDWMSumV Usage Notes For the summary case, a row exists for each collection if the count of the queries run in that time frame (LowHist to HighHist) is greater than 0.

This combination causes each dispatcher to write its DBQL cache entries to a single AMP. This is important for database efficiency. For information about the possible values for the ExceptionValue column, see Appendix A: “View Column Values.” TDWMEstMemUsage Column This column returns the estimated memory (in MB) used to classify a query into a workload definition. 228 Data Dictionary Chapter 3: Views Reference QryLogTDWMV Possible Values for the StatementGroup Column Value Description UCAbort An unconditional abort from the session or Gateway vproc or Teradata Director Program kill between requests. This may reflect the abort of an open transaction. If an UCAbort occurs, the value is zero. AsynchAbort An asynchronous abort from the session or Gateway vproc or Teradata Director Program kill. Note: If the AsynchAbort occurs when the request is in the dispatcher, the StatementGroup column values are the usual values for the request, and an error is generated.

PersistentSpool Data Dictionary 243 Chapter 3: Views Reference QryLogV Usage Notes The LogonSource column is deprecated and will be replaced in a future release. For information about the LogonSource fields, see Appendix B: “LogonSource Column Fields and Examples.” The DBQLogTbl.ExtraFieldXX columns (where XX represents the number of the column) are reserved for future use. These fields will be converted to a column name in a future release. IterationCount Column This column logs the iteration count for the data parcel associated with a request. This value is NULL for requests with a single using data row and no using data row. NumFragments Column This column is NULL for static plans only. SessionTemporalQualifier Column When a DML or SELECT request refers to a temporal table but omits a temporal qualifier, the system uses the value of the session temporal qualifier. This is the session temporal qualifier in effect when the query is logged. For example, this column uses the ANSIQUALIFIER value if the session temporal qualifier is set to ANSIQUALIFIER for ANSI temporal tables. For more information about the session temporal qualifiers, see Temporal Table Support and ANSI Temporal Table Support. TDWMEstMemUsage Column This column returns the estimated memory (in MB) used to classify a query into a workload definition. TotalServerByteCount The TotalServerByteCount column is the total number of bytes read from or sent to foreign servers involved in the request. Possible Values for the CacheFlag Column 244 Value Description T Query is found in step cache. S Query is a parameterized query and a specific plan is generated. G Query is parameterized query and a generic plan is generated. A Query is a parameterized query and a specific always decision is taken. That is, each time a query is submitted using values are peeked at and the query is parsed. Data Dictionary Chapter 3: Views Reference QryLogV Possible Values for the CPUDecayLevel Column • 0 • 1 • 2 Possible Values for the IODecayLevel Column • 0 • 1 • 2 Possible Values for the LockLevel Column • NOLOCK • ACCESS • READ • WRITE • EXCLUSIVE • UNKNOWN Possible Values for the NumResultRows Column For an Enhanced Statement Status (ESS) client, the value 18,446,744,073,709,551,615 could mean that number or higher. Note: The value formatted as a decimal value is 18,446,744,073,709,551,616 due to float arithmetic. For a non-ESS client, a warning message is returned if the actual activity count exceeds 4294967295. The same value (modulo 2^32) is logged in the NumResultRows column. The value 4294967295 along with the warning message indicates the actual counter is one of the following: 1 A multiple of 4294967296 minus 1. 2 Is equal to 18,446,744,073,709,551,615. 3 Is greater than 18,446,744,073,709,551,615. The maximum internal counter is 18,446,744,073,709,551,615. The value 4294967295 or less, without the warning message, is the actual row count. Data Dictionary 245 Chapter 3: Views Reference QryLogV Possible Values for the QueryText Column Value Description Unavailable and the RequestNum column value is zero. An unconditional abort (UCAbort) from the session or Gateway vproc or Teradata Director Program kill between requests. This may reflect the abort of an open transaction. * SQL query An asynchronous abort (AsynchAbort) from the session or Gateway vproc or Teradata Director Program kill naming a specific request number. If the abort occurs when the request in the dispatcher, the StatementType column and StatementGroup column values are the usual values for the request, and the error code indicates that the request was aborted. Possible Values for the QueryRedriven Column Value Description E The request was re-parsed due to an internal Parser error. M The request was re-parsed due to an internal Parser memory limit. R The request was re-driven due to a database restart. N The request was not redriven or re-parsed. Possible Values for the RedriveKind Column Value Description '' Not participating. MN Memory nonfallback responses. Possible Values for the RequestNum, StatementGroup, and StatementType Columns 246 Value Description UCAbort An unconditional abort from the session or Gateway vproc or Teradata Director Program kill between requests. This may reflect the abort of an open transaction. If an UCAbort occurs, the value is zero. Data Dictionary Chapter 3: Views Reference QryLogV Value Description AsynchAbort An asynchronous abort from the session or Gateway vproc or Teradata Director Program kill. Note: If AsynchAbort occurs, the value is the normal client request number. If the AsynchAbort occurs when the request is in the dispatcher, the StatementType and StatementGroup column values are the usual values for the request, and an error is generated. Possible Values for the ThrottleBypassed Column Value Description 1 ThrottleBypass ruleset attribute is set. 0 ThrottleBypass ruleset attribute is not set. Possible Values for the TTGranularity Column Value Description LOGICALROW Row is timestamped with the time the row is processed by the AMP. REQUEST Row is timestamped with the time the request is submitted. TRANSACTION Row is timestamped with the time when the first non-locking reference is made to a temporal table, or when the built-in function TEMPORAL_TIMESTAMP is first accessed during the transaction. Possible Values for the UtilityInfoAvailable Column Value Description Y SQL request has utility information (for example, from DSA or the control SQL session of a load or export utility) logged in the DBQLUtilityTbl table. N SQL request does not have utility information logged in the DBQLUtilityTbl table.

If you specify Y, the data is contained in the XMLTextInfo column on behalf of the specific logging [Option], where Option represents the STATSUSAGE or XMLPlan. Possible Values for the XMLDocType Column Note: Teradata recommends that you use the Has[Option]Data and [Option]Enabled columns rather than the XMLDocType column directly, where Option represents the STATSUSAGE or XMLPLan. Queries against these columns allow you to specify a Y or N value rather than bit mapped values. For more information about these columns, see “Possible Values for the HasXMLPlanData, HasStatsUsageData, HasVerboseData, and HasDetailedStatsData Columns” or “Possible Values for the XMLPlanEnabled, StatsUsageEnabled, VerboseEnabled, and DetailedStatsEnabled Columns” on page 251. Possible Values for the XMLPlanEnabled, StatsUsageEnabled, VerboseEnabled, and DetailedStatsEnabled Columns For these columns, a value of Y or N can be specified. If you specify Y, the [Option], where Option represents the STATSUSAGE or XMLPlan, was enabled when the data in XMLTextInfo was logged.

RequestText Column The RequestText data reflects the definitions specified by the user. This may not always match the data returned by the SHOW TABLE statement, which reflects the reconstructed definitions as they exist in the Data Dictionary. For example, when obsolete syntax that is still supported is converted internally to current syntax, RequestText returns the submitted (obsolete) syntax, while SHOW TABLE returns the converted (current) syntax. If the table is renamed, the RequestText still contains the old table name. The new table name is not put in the RequestText. TemporalProperty Column Data Dictionary Value Description S A system-versioned system-time table. U A bitemporal (system-versioned system-time and valid-time) table.

Version and UtilVersion Columns The UtilVersion column may be zero or null for tables created prior to V2R6.0. For tables created in V2R6.0 or later, both Version and UtilVersion are initially one. The following table shows when the UtilVersion column is modified, and how it’s modified: New Value or UtilVersion UtilVersion Current Value Data Definition Change Any value Significant change (by an ALTER TABLE statement) to keep an archive from being restored or copied. = Version NULL or zero Not significant Version -1 Any other value Not significant No change The Version column is increased by one for any data definition change other than enabling or disabling journaling for the table. Version in the above table is the version after it’s been incremented. The following table shows how the UtilVersion column is checked when selected partitions are restored or copied: UtilVersion Value Requirements NULL or zero The Version of the archive must match the Version of the table Any other value If the archive UtilVersion is zero, the Version of the Archive must match the UtilVersion of the table; otherwise, the UtilVersion column of the archive must equal the UtilVersion of the table Note: To restore or copy selected partitions, the table must already exist.

For information about Teradata Studio Express and to download the tool, go to: http://developer.teradata.com/tools/articles/teradata-studio-express-14-00-now-available How Tables Are Created The Data Dictionary tables are created during system initialization (SysInit), by the Table Initialization Program, or both. The tables store information about the system (system metadata) that is essential for it to function. The information is also essential to users that are responsible for managing the system. The system automatically updates the information in the tables to reflect the current state of the system. Accessing Tables Data Dictionary tables can be accessed only by users who have the required privileges to the tables. Access to the tables is strictly controlled to ensure that users (including system administrators) cannot modify them. Notice: To ensure that the system functions properly, do not modify or delete any Data Dictionary tables. Use Data Dictionary views to access data in the tables to ensure that the tables are not accidentally modified or deleted. Non-Hashed Tables When a table is nonhashed, all of the rows of the table are kept on a single AMP. For example, the DBC.DatabaseSpace table only keeps track of the space for a single AMP. Similarly, recovery tables only contain the information necessary to recover any activity/transaction that occurred on their own AMP. The following table lists the nonhashed and NO FALLBACK Data Dictionary tables.

The following tables are contained in the DBCExtension system database. Table Description GLOP_Map The GLOP_Map table contains the possible mappings for the particular set. GLOP_Set The GLOP_Set table describes the type of mapping for a set Glop_Data The GLOP_Data table describes the actual data to be mapped for a particular GLOP set reference. Related Topics For information on the DBCExtension.GLOP_Add, DBCExtension.GLOP_Remove, DBCExtension.GLOP_Change, and DBCExtension.GLOP_Report stored procedures that provide user access to the tables, see SQL External Routine Programming or refer to the table column definitions in Teradata Administrator, Teradata SQL Assistant, or Teradata Studio Express. 350 Data Dictionary Chapter 4: Data Dictionary Tables Updating Tables Updating Tables When a data definition statement is processed, the system tables are updated automatically. When a table is changed by an ALTER, CREATE, DROP, or RENAME statement, the Teradata Database automatically increments the version count for that table. For more information about creating, changing, and dropping tables, see SQL Data Definition Language. You cannot use the INSERT or UPDATE, or DELETE SQL commands to alter the Data Dictionary in any way. Character Data Character data in the Data Dictionary affects the following kinds of view columns: • Object Name • Text Strings • Other Character Data Object Names To make the Data Dictionary field definitions consistent across all Teradata platforms, the following attributes apply to each object name: • All object name columns are VARCHAR(128) CHARACTER SET UNICODE. • The default format for the object names is defined as X (128). Text Strings In the Data Dictionary, there are object names, SQL Text, and various other fields (for example, Title) that are Unicode. Other Character Data The server character set of non-object name character fields in the Data Dictionary is Latin. These fields (for example, CHAR(1) or CHAR(2)) have a fixed set of values (for example, Y, N, A, CV, and so on) and contain characters from U+0020 to U+007F (for example, A is U+0041). For more information about server character sets, see International Character Set Support. Maintaining System Logs Some Data Dictionary tables are in the form of logs, which accumulate increasing amounts of data over time. To avoid excess use of perm space, you should periodically delete older Data Dictionary 351 Chapter 4: Data Dictionary Tables Maintaining System Logs information from the log tables using either SQL DELETE requests or the Log Table Cleanup function in Teradata Viewpoint. Note: Older log data can also be transferred to other storage media if site policy requires longterm log record retention. You can create backup log tables to store log history and periodically copy data from the active logs and archive it to backup tables or long-term table storage. using the BTEQ .EXPORT command, FastExport, or a Backup and Restore (BAR) Software. Data Dictionary Logs that Require Manual Purging Logs Description Logs that can be either purged manually or using Teradata Viewpoint. Access Log (DBC.AccLogTbl) Data collected as defined in a BEGIN LOGGING statement, for each privilege check of an attempted user access of a database object. DBQ Logs: Data collected during database query logging (DBQL), if DBQL is enabled. • • • • • • DBC.DBQLSummaryTbl DBC.DBQLStepTbl DBC.DBQLogTbl DBC.DBQLObjTbl DBC.DBQLExplainTbl DBC.DBQLSqlTbl Event Log (DBC.EventLog) Data collected automatically by the system for each user logon event.

In Doubt transaction Log (DBC.InDoubtResLog) Contains a row for each transaction where completion was in doubt. Manually Deleting Old Log Data You can use the Teradata SQL DELETE statement to purge outdated log data, for example DBC.LogOnOff log data. Note: The user executing the SQL statement must have the DELETE privilege on the corresponding view. For example: You can purge DBC.LogOnOff log data based on age. Teradata recommends retaining 90 days of log data and purging directly from the DBC.EventLog table. DELETE FROM DBC.EventLog WHERE (DATE-DateFld) > 90; You can purge information for an account after a cost accounting period has closed.

The LogonSource column includes information about the source of sessions logged on from a client, including information on the TDP and job name. It is referenced in the following: • • Views: • LogOnOffV[X] • SessionInfoV[X] • QryLogV Tables: • EventLog • SessionTbl Mainframe-Attached Systems Using the CLIv2 API The origin of the CLIv2 mainframe session being reported, such as the user ID or session number of the client system. LogonSource can contain the following names and identifiers. Unless otherwise noted, each of the LogonSource string fields contains eight characters. Field Name Description Operating System Name Name of the client operating system for this logon. (Field 1) The valid name is MVS. TDP ID Unique identifier for the mainframe TDP controlling this logon. (Field 2) Job Name This is the job name. (Field 3) Environment Name The valid environments are BATCH, CICS, IMS, and TSO. (Field 4) Data Dictionary 363 Appendix B: LogonSource Column Fields and Examples LogonSource Column Field Name Description User ID from Security Product This is the user ID provided by the security product in use. Note: If no security product is in use, this is blank. (Field 5) Group from Security Product This is the group ID provided by the security product in use. (Field 6) If no security product is in use, this is blank. Program Name Use of this field is deprecated because it is not possible to determine whether it specifies an executable application name or a unique identifier provided by an application using the CLIv2 Workload specification (see Teradata Call-Level Interface Version 2 Reference for Mainframe-Attached Systems). (Field 7) Instead, you should use the Actual Program Name field, which provides a reliable name for the executable application Coordinator Name (Field 8) Name of the Coordinator if the logon is part of a two-phase commit logon. This is used only by the CICS and IMS mainframe transaction managers; otherwise, it is blank. Transaction ID (Field 9) Unique identifier for the transaction as determined by the transaction manager. This is used only by the CICS and IMS mainframe transaction managers; otherwise, it is blank. Terminal ID Unique identifier for the terminal as determined by CICS. (Field 10) This is used only for CICS; otherwise, it is blank. User/Operator ID Unique identifier for the user or operator as determined by CICS. (Field 11) This is used only for CICS; otherwise, it is blank. Actual Program Name This field contains the name of the executable application. (Field 12) Job ID This field contains the job ID. (Field 13) 364 Data Dictionary Appendix B: LogonSource Column Fields and Examples LogonSource Column Field Name Description Format ID Format identifier that can be used to parse the earlier positional information in the LogonSource attribute. If the field ends with the following four characters, the format ID is present: (Field 14) LSS Note: In the example above, the first character of the four character format ID is a blank space. The first set of two characters indicate the number of values found before the Actual Program Name, which is either 07 or 11. The second set of two characters indicates the version of the format ID. If the value is 01, the field contains the Job ID. If the value is 02, the field contains both the Actual Program Name and the Job ID value. If no Format ID is present, no Job ID value exists and only the first 7 or 11 fields of the LogonSource string are present. Self-Defining EBCDIC Items (Field 15 or later) The following self-defining EBCDIC items have variable lengths and contain the specified information within the parentheses that follow the field name in the LogonSource string: • TDP(): TDP release ID. See Teradata Director Program Reference. • CL2(): CLIv2 release ID. See Teradata Call-Level Interface Version 2 Reference for Mainframe-Attached Systems. • SESSDESC(): Descriptive information specified by the application using the CLIv2 Session-desc specification. See Teradata Call-Level Interface Version 2 Reference for MainframeAttached Systems. • WORKLOAD(): Information specified by the application using the CLIv2 Workload specification. The information is intended to be used by Teradata Database. See Teradata Call-Level Interface Version 2 Reference for Mainframe-Attached Systems. Note: If the length of the self-defining items causes the LogonSource string to exceed 128 characters, Teradata Database truncates them as necessary and indicates the truncation with the string ‘…)’ if enough space remains to do so. Workstation-Attached Systems Using CLIv2 API The origin of the CLIv2 workstation-attached session being reported, such as the user ID or session number of the client system. Note: The corresponding LogOnOffV[X] or SessionInfoV[X] column shown in the table below appears in the LogOnOffV[X] and SessionInfoV[X] views and EventLog and SessionTbl tables only. Teradata strongly recommends that applications which use the LogonSource fields instead use the corresponding LogOnOffV[X] or SessionInfoV[X] columns, also referred to as ClientAttribute columns.

Typically, stored procedures consist of: • a procedure name • input and output parameters • procedure body. For more information see SQL Stored Procedures and Embedded SQL. For each stored procedure, the database includes a stored procedure table that contains the stored procedure body you write and the corresponding compiled stored procedure object code. Data dictionary tables contain stored procedure parameters and attributes. The Transient Journal (TJ) record holds the host request number for a stored procedure, in addition to the DBS request number, to return a correct response to the query status for a request after DBS restarts. Corresponding Tables and Logging Rules Stored procedure object information is stored in: • DBC.TVM • DBC.TVFields • DBC.AccessRights • DBC.AccLogRuleTbl The SPObjectCodeRows column in the DBC.TVM table references information on the status of the stored procedure. The value of this column indicates the following stored procedure creation-time attributes: Data Dictionary • Session mode • Platform type • Print option • Stored procedure text storage option • Version number • Warning option • Hardware architecture 387 Appendix C: Database Objects Tables The SPParameterType column in the DBC.TVFields table contains information about the stored procedure parameters. Parameter types for this column include IN, INOUT, or OUT. The following table lists the privileges stored in the AccessRights table and their corresponding logging rules stored in the AccLogRuleTbl table.
