Item 1
Table ACCOUNTS has the following structure:
ACCT_ID INT PRIMARY KEY NOT NULL
ACCT_NAME VARCHAR (100)
DEPT_ID INT
DEPT_NAME VARCHAR (100)
Another table named DEPARTMENT contains the list of all department IDs and name for the organization.
To populate the DEPT_ID and DEPT_NAME columns of the ACCOUNTS table the following SQL statement
is issued:
INSERT INTO accounts (dept_id, dept_name)
SELECT dept_id, dept_name FROM DEPARTMENT
What is the result of the INSERT statement?
{
{
{
~
The INSERT statement will execute successfully.
The INSERT statement will fail because the statement has a syntax error.
The INSERT statement will execute successfully only if the subquery returns one row.
The INSERT statement will fail because the column ACCT_ID cannot accept null values.
Explanation:
The INSERT statement will fail because the column ACCT ID cannot accept null values. For an INSERT
statement that uses a subquery the INSERT statement must either list all the columns of the table or the
remaining columns of the table that do not appear in the column list must accept null values or have a
default constraint defined.
The INSERT statement will execute successfully only if the NOT NULL columns in the table are either
marked as NULL or have a default constraint defined.
The option, the INSERT statement will fail because the statement has a syntax error, is incorrect because
the statement does not have any syntax errors. The correct syntax of the INSERT statement is
INSERT INTO [table name | view name] < ( [ column name], ..., ...) > [SELECT
statement].
The option, the INSERT statement will execute successfully only if the subquery returns one row, is
incorrect. The subquery can return more than one row. However, the number of values returned by the
subquery must match the column name list of the INSERT statement and the data types should be
compatible.

Item 3
Which of the following isolation level would be appropriate to use while querying read-only databases?
{
{
{
~
Read Stability lsolation Level
Cursor Stability lsolation Level
Repeatable Read lsolation Level
Uncommitted Read lsolation Level
Explanation:
Uncommitted Read lsolation Level would be appropriate to use while querying read-only databases. A
transaction using this isolation level would not acquire any locks on the rows retrieved as a result of the SQL
query unless another concurrent transaction attempts to alter or drop the table from which the rows were
fetched. In addition, the rows cannot be modified because the database is read-only.
Read Stability lsolation Level would be appropriate to use when some level of concurrency between
transactions is desirable, and the rows retrieved as a result of the SQL query need to remain stable for the
duration of the transaction.
Cursor Stability lsolation Level would be appropriate to use when the maximum level of concurrency
between transactions is desired and when queries should not return uncommitted data values from other
transactions.
Repeatable Read lsolation Level would be appropriate to use when you do not want other transactions to
modify the rows retrieved by the transaction using this isolation level. This isolation level is desirable when
you do not want the same query to return different results when executed again.
Objective:

Item 4
Which event best describes the following situation?
Transaction A issues a SELECT query and retrieves a set of rows. When the same SELECT query is issued
again by transaction A, the result set is different.
{
{
{
~
Phantoms
Dirty Reads
Lost Updates
Nonrepeatable Reads
Explanation:
The event Nonrepeatable Reads describes the scenario in which a transaction issues the same SELECT
statement twice and receives different results each time. Transaction A reads a set of rows and another
transaction, transaction B, modifies or deletes the same set of rows and commits the changes. When
transaction A issues the same query again, the result may be different because of inserts by transaction B
or deletes by transaction B.
The event Phantoms describes the scenario in which transaction A issues a query based on some matching
criteria and retrieves the records. When the same query is issued again, the query retrieves the rows that
were not available in the initial result set. For example, transaction A issues a query and the query reads a
row of data based on some matching criteria. Another transaction, transaction B, then inserts some records
in the table that matches the criteria for transaction A. Transaction A issues the same query again, the query
will fetch records that were not available initially and were added to the table as a result of the insert
operation executed by transaction B.
The event Dirty Reads describes the scenario in which a transaction reads data that is not yet committed by
another transaction. For example, transaction A reads data that is not yet committed by transaction B. If
transaction B rolls back the changes, transaction A would have read data that never existed.
The event Lost Updates describes the scenario in which two transactions attempt to update the same set of
data simultaneously and one of the transaction loses the data. For example, if transaction A updates a set of
rows, and
then transaction B updates the same set of rows, the update performed by Transaction A is lost.

Item 5
Which of the following statements is NOT true about primary key constraint?
{
{
{
~
Only one primary key can be defined on a table.
Primary key columns do not allow duplicate values.
The primary key column does not accept null values.
The primary key column allows a single null value to be stored in the column.
Explanation:
The statement the primary key column allows a single null value to be stored in the column is not true.
Primary key columns do not allow null values to be stored because the column defined as primary key must
have a NOT NULL constraint. Primary keys, like unique constraints, do not allow duplicate values to be
stored in the column. However, as compared to unique constraints, there can be only one primary key in a
table.

Given the following command:
DROP DATABASE my_db
Which of the following statements regarding this command is NOT true?
{
{
~
{
The command will remove all the contents of the MY_DB database.
Only users with the SYSADM or SYSCTRL authorities can issue this command.
The database's tablespace storage containers are not made available for use by other databases.
The command will remove the entries for MY_DB from both the system and local database
directories.
Explanation:
The option stating that the database's tablespace storage containers are not made available for use by other
databases is not true. Dropping a database will mark its tablespace storage containers for use by other
databases.
The other options stating that the command will remove all the contents of the MY_DB database, the
command will remove the entries for MY_DB from both the system and local database directories, and only
users with SYSADM or SYSCTRL authorities can issue this command are correct regarding the DROP
DATABASE command.

Item 7
Program one in the application issues the following statements:
CREATE TABLE t.table1 (col1 INTEGER, col2 VARCHAR(100))
COMMIT
Program two in the application then issues the following statements:
INSERT INTO t.table1 VALUES (1,'IDENTITY1')
ROLLBACK
INSERT INTO t.table1 VALUES (2,'IDENTITY2')
COMMIT
DELETE FROM t.table1 WHERE col1='2'
INSERT INTO t.table1 VALUES (3,'IDENTITY3')
ROLLBACK
INSERT INTO t.table1 VALUES (4,'IDENTITY4')
COMMIT
UPDATE t.table1 SET col1='5' WHERE col1='4'
ROLLBACK
INSERT INTO t.table1 VALUES (6,'IDENTITY6')
ROLLBACK
INSERT INTO t.table1 VALUES (7,'IDENTITY7')
COMMIT
Program three then issues the following SELECT statement:
SELECT * FROM t.table1
How many rows are returned as a result of the SELECT statement?
{ 0
{ 1
{ 2
~ 3
Explanation:
In the given scenario, three rows are returned as a result of the SELECT statement. The rows will fetch the
values two, four, and seven for the COL1 column. Because all other DML statements are rolled back, only
three rows will be fetched from the table.
The options stating that zero, one, and two rows will be returned as a result of the SELECT statement are
incorrect. Because only three DML statements have been committed to the database as a result of the
COMMIT statement, three rows will be returned by the SELECT statement.

Item 8
The table EMPLOYEE contains the following columns:
EMP_ID
FIRST_NAME
LAST_NAME
The EMP_ID column is defined as the primary key column of the table. The SALARY table contains the
following columns:
EMPID
DAYS_WORKED
GROSSSALARY
The EMPID column has a referential integrity constraint that references the EMP_ID column of the
EMPLOYEE table. The referential integrity constraint includes the ON DELETE RESTRICT clause. The
SALARY table also has a CHECK constraint defined on the GROSS_SALARY column and the
DAYS_WORKED column. The CHECK constraint enforces the following conditions:
- GROSS_SALARY values should be greater than zero
- DAYS_WORKED values should be between 1 and 31
Which two of the following operations will enforce the constraints defined on the SALARY table? (Choose
two.)
…
;
;
…
…
Deletion of a row in the table SALARY
Updation of a row in the table SALARY
Deletion of a row in the table EMPLOYEE
Addition of a new column to the table SALARY
Rollback of a row deletion on the table SALARY
Explanation:
Updating a row in the SALARY table and deleting a row in the EMPLOYEE table will enforce the constraints
defined on the SALARY table. The DB2 Database Manager enforces the table CHECK constraints
whenever there is insert or update operation on the table. In this scenario, the CHECK constraint will be
enforced whenever a row is updated in the SALARY table. The SALARY table also has a referential integrity
constraint defined on the EMPID column.
The foreign key is defined with the rule ON DELETE RESTRICT. If there are corresponding rows in the
dependent SALARY table, the deletion rule will not allow the rows to be deleted from the parent EMPLOYEE
table. In this scenario, the referential integrity constraint will be enforced whenever there is deletion of rows
in the parent EMPLOYEE table.
The operations deletion of a row in the SALARY table, addition of a new column to the SALARY table, and
rollback of a row deletion on the SALARY table are incorrect. Rows can be deleted from the dependent table
even if there are corresponding rows in the parent table. However, the reverse is not true. Addition of a new
column to the SALARY table will not have any affect on the constraints. Rollback of a row deletion on the
SALARY table will simply undo the delete operation.

Explanation:
To process requests, the DB2 OLAP server supports both relational and multidimensional databases. The
DB2 OLAP server processes multidimensional requests that calculate, consolidate, and retrieve information
from a multidimensional database, a relational database, or both.

Which two of the following statements will allow all users in the database to access the EMPLOYEE table
using the name EMP instead of EMPLOYEE? (Choose two.)
;
;
…
…
…
CREATE VIEW emp
CREATE ALIAS emp
CREATE INDEX emp
CREATE TABLE emp
CREATE TRIGGER emp
Explanation:
The CREATE VIEW emp and CREATE ALIAS emp statements will allow all users in the database to access
the EMPLOYEE table with the name EMP. An alias is an alternate name for a table or an existing alias.
Views will also allow all users to access the table with a different name. You will need to issue the following
statement to create the view:
CREATE VIEW emp AS SELECT * FROM employee
The options CREATE INDEX emp, CREATE TABLE emp, and CREATE TRIGGER emp are incorrect.
You use the CREATE INDEX emp statement to create an index on the table. An index is created on the
table to enforce uniqueness in the columns. You use the CREATE TABLE statement to create another table
named EMP in the database. You use the CREATE TRIGGER emp statement to create a trigger on a table.
Triggers are used to perform some actions on the tables whenever there is DML activity on the table.

Explanation:
The statement SELECT * FROM employees WHERE deptcode IS NULL will display all the rows from
the EMPLOYEE table with no DEPTCODE value. The NULL predicate is used to denote a null, missing, or
absence of value a the column.
The statement SELECT * FROM employees WHERE deptcode = " "is incorrect. NULL, zero(0), and
blank (" ") are not same. NULL is used to indicate an absence of value, while zero and blank (empty string)
are actual values that can be stored within a column.
The statement SELECT * FROM employees WHERE deptcode = NULL is incorrect. The correct syntax
of using the NULL predicate is < column name > IS NULL.
The statement SELECT * FROM employees WHERE deptcode IS BLANK is incorrect. There is no
BLANK predicate in DB2 UDB Database.

Which of the following will allow you to reference an index by name, within an SQL statement?
{
{
{
~
Altering the index
Updating the index
Querying the index
Dropping the index
Explanation:
Indexes can only be referenced by name within a SQL statement when creating or dropping them. Other
than these two actions, an index cannot be referenced by name. The CREATE INDEX statement is used to
create an index.
The DROP INDEX statement is used to remove an existing index from the database.
Altering an index will not allow you to reference the index by name. Alteration of an index is not possible. If
you need to alter an index, you should drop and re-create the index.
Updating an index will not allow you to reference an index by name. You cannot update an index manually.
Indexes are maintained automatically by the DB2 Database Manager.
Querying an index will not allow you to reference the index by name. Selecting an index within an SQL
statement is not allowed. Indexes help improving performance of queries on the base tables on which they
are defined.

Item 13
A user-defined function accesses the EMPLOYEE and DEPARTMENT tables. The function performs insert
operations on the EMPLOYEE table and update operations on the DEPARTMENT table.
Which of the following combinations of privileges will allow user JOHN to run the user-defined function with
the least administrative effort?
~
{
{
{
EXECUTE privilege on the function
INSERT privilege on EMPLOYEE and EXECUTE privilege on the function
INSERT privilege on EMPLOYEE and UPDATE privilege on DEPARTMENT
UPDATE privilege on DEPARTMENT and EXECUTE privilege on the function
Explanation:
The EXECUTE privilege on the function will allow the user to execute the function. This is the minimum
privilege required for user JOHN to execute the user-defined function. Users who have been granted the
EXECUTE privilege on the function do not need additional privileges on the tables that the function
references.
The statement INSERT privilege on EMPLOYEE and EXECUTE privilege on the function will allow user
JOHN to execute the user-defined function. However, you need to grant the minimum privileges to user
JOHN to execute the function. The user does not require additional INSERT privilege on the EMPLOYEE
table.
The statement INSERT privilege on EMPLOYEE and UPDATE privilege on DEPARTMENT will grant user
JOHN the ability to perform insert operations on the EMPLOYEE table and update operations on the
DEPARTMENT table. However, this statement will not grant user JOHN the ability to execute the function.
The statement UPDATE privilege on DEPARTMENT and EXECUTE privilege on the function will allow user
JOHN to execute the user-defined function. However, you need to grant the minimum privileges to user
JOHN to execute the function. The user does not require additional UPDATE privilege on the
DEPARTMENT table.

Item 14
A view is created on a table with the following SQL statement:
CREATE VIEW v1 AS SELECT A, B, C FROM tab1 WHERE A < 200
The following INSERT statement is issued next:
INSERT INTO v1 VALUES (300,3,3)
Which of the following about the INSERT statement is true?
{
{
~
{
The INSERT statement fails.
The INSERT statement executes successfully and the record is visible to the view.
The INSERT statement executes successfully but the record is not visible to the view.
The INSERT statement executes successfully but the A column is assigned a null value.
Explanation:
The INSERT statement executes successfully but the record is not visible to the view. This is because the
record violates the view definition. The statement executes successfully because the view is not created
using the WITH CHECK OPTION clause. If the view had been created using the WITH CHECK OPTION
clause, the INSERT statement would fail. However, the record will not be displayed if a SELECT statement
is issued against the view.
The option stating that the INSERT statement fails is incorrect. If the view had been created using the WITH
CHECK OPTION clause, the INSERT statement would fail.
The option stating that the INSERT statement executes successfully and the record is visible to the view is
incorrect. The record will not be visible to the view because the record violates the view INSERT statement
will not fail because the view is not created using the WITH CHECK OPTION clause.
The option stating that the INSERT statement executes successfully but the A column is assigned a null
value is incorrect. The INSERT statement will either execute successfully or will fail depending upon the
view definition. If the statement is successful, the A column will be assigned the specified value and not a
null value.

You issue a SQL statement on the STORES table that returns a value of 4. Which of the following
statements did you issue?
{
{
~
{
SELECT AVG(price) FROM stores
SELECT SUM(price) FROM stores
SELECT COUNT(price) FROM stores
None of these SQL statements will return a value of 4.
Explanation:
The following SQL statement will return a value of 4:
SELECT COUNT(price) FROM stores
The COUNT function returns the total number of non-null values found in the column specified. In this
scenario, the total number of non-null values in the PRICE column is 4.
The following SQL statement will not return a value of 4:
SELECT AVG(price) FROM stores
This statement will return the value 4.5. The AVG function returns the sum of values in the column specified
divided by the number of values found in that column.
The following SQL statement will not return a value of 4:
SELECT SUM(price) FROM stores
This statement will return the value 18. The SUM function returns the sum of the values in the column
specified.
The option none of these SQL statements will return a value of 4 is incorrect. In the given scenario, the
statement that uses the COUNT function will return a value of 4.

The LOCATION table keeps track of all the events at different locations. Different events are conducted at a
given location. Which of the following SELECT statements will produce the total number of different events
held at each location?

location_id
{ SELECT COUNT(*), DISTINCT(location_id) FROM location
{ SELECT DISTINCT (event_type) FROM location GROUP BY location_id
~ SELECT location_id, COUNT(DISTINCT event_type) FROM location GROUP BY
location_id
Explanation:
The following statement will produce the total number of different events held at each location:
SELECT location_id, COUNT(DISTINCT event_type) FROM location GROUP BY
location_id
In the given scenario, the DISTINCT clause will eliminate any duplicate occurrence of records. The COUNT
function will then return the total number of non null events. The GROUP BY clause will aggregate the data
and produce a count of the different events for each location.
The following statement will not produce the total number of different events held at each location:
SELECT UNIQUE(location_id), COUNT(event_type) FROM location GROUP BY
location_id
This statement will fail because there is no UNIQUE clause in the DB2 UDB database.
The following statement will not produce the total number of different events held at each location:
SELECT COUNT(*), DISTINCT(location_id) FROM location
This statement will fail when executed because the statement uses the COUNT group function without a
GROUP BY clause.
The following statement will not produce the total number of different events held at each location:
SELECT DISTINCT (event_type) FROM location GROUP BY location_id
This statement will fail when executed because the statement uses a GROUP BY clause without a group
function. The statement will generate an error indicating that EVENT_TYPE is not a group by expression.

You need to set up a client to access the DB2 UDB server from a Solaris machine. The client must be able
to issue SQL statements and access the data on the server. What is the minimum software requirement for
the Solaris client?
~
{
{
{
DB2 run-time client
DB2 administration client
DB2 personal developer's edition
DB2 application development client
Explanation:
In this scenario, the DB2 run-time client should be installed on the Solaris client machine to allow the client
to issue interactive SQL statements. The DB2 run-time client software allows a client to connect with a DB2
UDB and/or a DB2 Connect server. The DB2 run-time client enables the client to issue SQL statements to
access the data stored on the server. The DB2 run-time client also allows the applications using ODBC/CLI,
JDBC, SQLJ, and OLE DB to run on the client and interact with data on a DB2 UDB and/or a DB2 Connect
server. Some of the operating systems on which the DB2 run-time client can be installed include AIX, HPUX, Solaris, Linux, Windows NT, and Windows 2000.
The DB2 administration client enables the client to perform administrative operations on a DB2 UDB
database from a client workstation and also enables basic connectivity with a DB2 UDB and/or a DB2
Connect server. The DB2 administration client is included with the Control Center and the Configuration
Assistant.
The DB2 personal developer's edition allows a client to develop, run, and test applications that interact with
the DB2 UDB databases using these methods:
•
•
•
•
•
Embedded Structured Query Language (SQL)
IBM's Call Level Interface (CLI)
Java Database Connectivity (JDBC)
SQL Java (SQLJ)
DB2 Application Programming Interfaces (APIs)
The DB2 application development client enables the client to perform administrative operations on a DB2
UDB database from a client workstation and provides basic connectivity with a DB2 UDB and/or a DB2
Connect server. Using the DB2 application development client, the client can also develop, test, and run
applications designed to interact with a DB2 database.

Which of the following extenders allow you to search a text document stored in a DB2 UDB database for
words that sound like "drought"?
{
~
{
{
DB2 AVI Extender
DB2 Text Extender
DB2 XML Extender
DB2 Spatial Extender
Explanation:
The DB2 Text Extender allows you to store and search information for similar-sounding words from text
documents stored in the database or in the file system. The DB2 Text Extender allows you to build queries
that will search and extract information from text documents based on the search criteria, including a
specific word, a specific phrase, or similar-sounding or similar spelled words.
The DB2 AVI Extender is used to store and manipulate audio, video, and images.
The DB2 XML Extender allows you to store and manipulate the extensible markup language (XML)
documents in a DB2 UDB database. The XML documents can be either stored in the database or in the file
system. The DB2 XML Extender allows you to extract the information from XML documents and store them
in tables and columns.
The DB2 Spatial Extender is used to store, generate, and analyze geo-spatial data. The DB2 Spatial
Extender allows you to store the spatial data along with the nonspatial data in the DB2 UDB database and
present the data in a three-dimensional format.

Given the following statements:
CREATE TABLE tab1 (col1 PRIMARY KEY NOT NULL, col2 NOT NULL)
CREATE UNIQUE INDEX idx ON tab1(col1)
How many indexes are created on the table?
{ 0
~ 1
{ 2
{ 3
Explanation:
One index is created on the table. The index is created automatically by the DB2 Database Manager for the
primary key constraint defined on the COL1 column. The DB2 Database Manager creates a unique index for
unique or primary key constraints defined on a column if no index exists. The second statement will fail
because you cannot create additional unique indexes or constraints on the same columns. No indexes are
created to support the not null constraints.
The option stating zero indexes is incorrect. One index will be created to support the primary key constraint
defined on the COL1 column.
The option stating two indexes is incorrect. The DB2 Database Manager will create a unique index to
support the primary key constraint defined on the COL1 column. The DB2 Database Manager will not allow
you to create additional unique indexes on the COL1 column.
The option stating three indexes is incorrect. Only one index will be created by the DB2 Database Manager
to support the primary key constraint defined on the table column COL1. The second statement will fail
because you cannot create additional unique indexes or constraints on the same columns. No index is
created to support the not null constraint.

12451
89009
98000
99052
Explanation:
In the given scenario, the last MACHINE_ID obtained from the table is 89009. The default sorting order for
the ORDER BY clause is ascending. An ascending sort will display the values from lowest to highest. During
an ascending sort, the null values will be displayed last. In this scenario, the null value pertaining to
MACHINE_ID 89009 will cause this value to be displayed last.
The options 12451, 98000, and 99052 are incorrect. These values will not be displayed last.

{ CATALOG TCPIP NODE my_host REMOTE my_host PORT 5000 OSTYPE os/400
CATALOG DATABASE sample AS sample AT NODE my_host AUTHENTICATION SERVER
Explanation:
To establish a connection between the client and the server, you use the CATALOG TCPIP NODE and
CATALOG DATABASE commands. You need to catalog both the node and the database to establish a
connection. The correct syntax for both the commands is used only in the following statement:
CATALOG TCPIP NODE my_host REMOTE my_host SERVER 5000 OSTYPE os/400
CATALOG DATABASE sample AS sample AT NODE my_host AUTHENTICATION SERVER
The other options are incorrect because the syntaxes are not valid.

Explanation:
The user MARTIN can only change his password. The CONNECT database privilege allows the user
MARTIN to establish a session with the database. However, the user MARTIN will not be able to perform
any other tasks, except changing his password. This is because the user MARTIN has not been granted any

{
Sequences and identity columns are alike.
Sequences are used to automatically generate values.
Consecutive values can differ by any specified increment value.
PREVAL and NEXTVAL are two expressions used with sequences.
Explanation:
The statement sequences and identity columns are alike is not true. Sequences and identity columns are
used to automatically generate data values. Unlike an identity column, which is tied to a particular column or
table, sequences are not tied to any columns or tables in the database.
The statements sequences are used to automatically generate values, consecutive values can differ by any
specified increment value, and PREVAL and NEXTVAL are two expressions that help use of sequences are
true.
The expression PREVAL returns the recent value for the sequence and the expression NEXTVAL returns
the next value for the sequence. In addition, consecutive values in a sequence can differ by any specified
value; however, the
default value is 1.

Item 26
A hotel agent seeking reservations for a group of customer accesses the hotel reservation application and
issues a query. The query for a date range displays 20 rooms as vacant. The hotel agent then refreshes the
list and finds that the number of vacant rooms for the same range of date is now 30.
Which of the following lsolation Level is the hotel reservation application bound to?
~
{
{
{
Read Stability
Cursor Stability
Repeatable Read
Uncommitted Read
Explanation:
The hotel reservation application is bound to the Read Stability lsolation Level. An application bound to this
isolation level will allow you to change the status for any room in the hotel that does not appear in the
agent's query results. Transactions will also be able to cancel the room reservations for rooms that have
been reserved for the date range specified by agent. When the agent refreshes the list again, the list
produced may contain new rooms that were not displayed the first time the list was generated.
The hotel reservation application is not bound to the Cursor Stability lsolation Level. An application bound to
this isolation level will allow users to change the status of any room in the hotel, except the room that the
agent is currently looking at, not all the rooms returned by the query. Other concurrent transactions will also
be able to make or cancel reservations for any room in the hotel with the exception of the room that the
agent is currently looking at.
The hotel reservation application is not bound to the Repeatable Read lsolation Level. An application bound
to this isolation level will allow you to change the status for any room in the hotel with the exception of rooms
that were not scanned in response to the agent's query. Transactions can also cancel or make reservations
for any room in the hotel that was not scanned in response to the agent's date range.
The hotel reservation application is not bound to the Uncommitted Read lsolation Level. An application
bound to this isolation level will allow you to change the status for any room in the hotel. Other concurrent
transactions will also be able to make or cancel reservations for any room in the hotel for any date range.

Explanation:
In the given scenario, two rows will be retrieved as a result of the SELECT query because only the second
and the fourth INSERT statements will succeed. The remaining INSERT statements will fail because of
CHECK constraint violations.
The options zero, three, and five rows are incorrect because three INSERT statements violate the CHECK
constraint and only two rows will be fetched as a result of the query.

Which of the following information is required to catalog a Windows 2000 connection to a remote Solaris
server?
~
{
{
{
Hostname
Password
Client’s operating system
Client’s workstation name
Explanation:
Hostname is required to catalog a Windows 2000 connection to a remote Solaris server. Cataloging a node
requires the hostname of the server. You need to have appropriate privileges on the client workstation to
catalog a node. Other information required to catalog a node includes service name, type of operating
system being used on the server workstation, and the alias name to be assigned to the node. If no alias
name is provided, the database name is used by default.
The options stating password, client's operating system, and client's workstation name are incorrect.
Cataloging is performed on the client workstation. Therefore, you do not need to provide information about
the client workstation.

SELECT * FROM tab1;
~
{
{
{
0

Explanation:
In the given scenario, zero rows will be returned as a result of the SELECT statement. This is because the
INSERT statements will fail.
In this scenario, the INSERT statements try to perform insert operation on a single column but provide the
values for all three columns of the table. To successfully insert data values in a single column the INSERT
statement must include a single value only and the remaining columns of the table must accept null values.
The other statements are incorrect. If the INSERT statements would have executed successfully, three rows
would have been returned by the SELECT statement.

Which of the following regarding indexes is NOT true?
{
{
{
~
Indexes locate data quickly.
Indexes enforce uniqueness.
Indexes require additional storage space.
Indexes hold locks for a longer period of time.
Explanation:
The statement indexes hold locks for a longer period of time is not true. Indexes help locate the data faster
thereby increasing concurrency in a multi-user environment and therefore locks are held for a brief period of
time.
The options indexes locate data quickly, indexes enforce uniqueness, and indexes require additional
storage space are true. Indexes store pointers that refer to rows in the base tables. Indexes are defined on
one or more columns in a base table. In addition, indexes enforce uniqueness and help the DB2 Database
Manager to locate data quickly and increase the response time of queries. Indexes require additional
storage space and may also decrease the
performance when there is increased update activity on the base table. This is because any data
modifications in the table also require the corresponding indexes to be updated.

Which clause will retrieve only the first 20 rows of the result data set when used in a SELECT statement?
{
{
{
~
TOP
MAXIMUM
OPTIMIZE
FETCH FIRST
Explanation:
The FETCH FIRST clause is used to restrict the result data set to a specified number of rows, in response to
a query. The FETCH FIRST clause is followed by a positive integer value, representing the number of rows
to be returned from the result data set and the words ROWS ONLY. The result data set generated in
response to a query can contain any number of rows but the result data set that is returned will contain the
number of rows that are specified by the FETCH FIRST clause. Therefore, if you need to retrieve only the
first 20 rows, you could do so by executing the SELECT statement. For example:
SELECT col1, col2 FROM table FETCH FIRST 20 ROWS ONLY
The other options stating TOP, MAXIMUM, and OPTIMIZE are incorrect. AII of these are invalid clauses.

ALTER TABLE region LOCK ROW
ALTER TABLE region LOCK TABLE
ALTER TABLE region LOCKSIZE ROW
ALTER TABLE region LOCKSIZE TABLE
Explanation:
The following statement will force the DB2 Database Manager to acquire table-level locks for every
transaction that accesses the table REGION:
ALTER TABLE region LOCKSIZE TABLE
The following statements will not force the DB2 Database Manager to acquire table-level locks for every
transaction that accesses the table REGION:
ALTER TABLE region LOCK ROW
ALTER TABLE region LOCK TABLE
This is because the statements are syntactically incorrect.
The following statement will not force the DB2 Database Manager to acquire table-Ievel locks for every
transaction that accesses the table REGION:
ALTER TABLE region LOCKSIZE ROW
This statement will force the DB2 Database Manager to acquire row-Ievel locks for every transaction that
accesses the REGION table. This is also the default behavior of the DB2 Database Manager.

Item 33
You need to ensure that a particular transaction is completely isolated from other transactions in the
database. Which isolation level should you use?
{
{
~
{
Read Stability lsolation Level
Cursor Stability lsolation Level
Repeatable Read lsolation Level
Uncommitted Read lsolation Level
Explanation:
The Repeatable Read lsolation Level completely isolates a transaction from other transactions in the
database. The Repeatable Read lsolation Level locks all the rows that are scanned as a result of the SQL
statement. A transaction using the Repeatable Read lsolation Level issues a SELECT statement twice and
the result of the SELECT statement will be the same. No other concurrent transaction can perform any
insert, update, or delete operations on the set of rows that are scanned by the transaction using the
Repeatable Read lsolation Level.
The Read Stability lsolation Level does not completely isolate a transaction from other concurrent
transactions in the database. The Read Stability lsolation Level will lock all the rows that are actually
retrieved as a result of the SQL statement. A transaction using the Read Stability lsolation Level issues a
SELECT statement twice and the result of the SELECT statement may not be the same. No other
concurrent transaction can perform any insert, update or delete operations on the set of rows that are
retrieved or modified by the transaction using the Repeatable Read lsolation Level.
The Cursor Stability lsolation Level locks the row that is currently being accessed by the cursor. AII the other
rows that are retrieved as a result of the updatable cursor are free from locking. The lock on the currently
accessed row is released when either the cursor moves to the next row or when the transaction is
terminated. Other concurrent transactions in the database are allowed to insert new rows into the table and
perform insert or update operations on the rows present on the either side of the cursor. A transaction using
the Cursor Stability lsolation Level issues a SELECT statement twice, and the result of the SELECT
statement may not be the same.
The Uncommitted Read lsolation Level is the least restrictive isolation level to which a transaction can be
bound. The rows retrieved by the transaction using this isolation level are locked only when another
transaction attempts to drop or alter the table from which the rows are retrieved.

Users who have been granted the Load (LOAD) authority cannot revoke the CONTROL privilege on any
database object. However, users who have been granted the LOAD authority cannot revoke any authorities
or privileges.
Users granted the System Control (SYSCTRL) authority cannot revoke the CONTROL privilege on any
database object. Users granted the SYSCTRL authority can only revoke the USE tablespace privilege.
Users granted the System Maintenance (SYSMAINT) authority cannot revoke the CONTROL privilege on
any database object. Users granted the SYSMAINT authority can neither grant nor revoke any privileges or

NAME VARCHAR(30) NOT NULL
FNAME VARCHAR(25) NOT NULL
DEPT_NO INTEGER
TITLE VARCHAR(25)
DEPARTMENT
DEPT_ID INTEGER NOT NULL PK
DEPT_NAME VARCHAR2(25)
The TITLE column can have three values: 'CLERK', 'ASSISTANT', or 'MANAGER'.
Which of the following SELECT statements will produce the name of the departments that have more than
three assistants?
{ SELECT dept_name
FROM employee JOIN department ON employee.dept_no = department.dept_id

{ SELECT dept_name
FROM employee e JOIN department d ON (e.dept_no = d.dept_id)
WHERE LOWER(title) = 'assistant' AND COUNT(*) > 3
~ SELECT d.dept_name
FROM employee e JOIN department d ON (e.dept_no = d.dept_id)
WHERE LOWER(title) = 'assistant'
GROUP BY dept_name
HAVING COUNT(emp_id) > 3
Explanation:
The following statement will produce the name of the departments that have more than three assistants:
SELECT d.dept_name
FROM employee e JOIN department d ON (e.dept_no = d.dept_id)
WHERE LOWER(title) = 'assistant'
GROUP BY dept_name
HAVING COUNT(emp_id) > 3
In the given scenario, the COUNT function will include only results with more than three assistants in the
table. The LOWER function will convert the strings in the TITLE column to lower-case, irrespective of how
the strings are stored in the column.
The following statement will not produce the name of departments that has more than three assistants:
SELECT dept_name
FROM employee JOIN department ON employee.dept_no = department.dept_id
WHERE UPPER(title) = 'ASSISTANT'
GROUP BY dept_name
HAVING emp_id > 3
Page 31 of 68
Information Management
Certification Sample Test 700 IBM DB2 UDB V8.1 Family Fundamentals (with Explanations).
This statement will return an error indicating that EMP_ID is not a group function because the HAVING
clause is used to restrict values already grouped by the GROUP BY clause.
The following statement will not produce the name of the departments that have more than three assistants:
SELECT dept_name
FROM employee
GROUP BY dept_no
HAVING LOWER(title) = 'assistant' AND COUNT(*) > 3
The statement is syntactically incorrect. The statement attempts to fetch the DEPT_NAME column values
from the EMPLOYEE table. There is no DEPT_NAME column in the EMPLOYEE table. This statement will
fail.
The following statement will not produce the name of the departments that have more than three assistants:
SELECT dept_name
FROM employee e JOIN department d ON (e.dept_no = d.dept_id)
WHERE LOWER(title) = 'assistant' AND COUNT(*) > 3
This statement uses a group function COUNT without the GROUP BY clause. This will cause the statement
to fail.

Which of the following privileges will grant ED the ability to perform the IMPORT operation on the
T.MONITOR1 table?
{
~
{
{
ALTER privilege ON t.monitor1 TO ed
INSERT privilege ON t.monitor1 TO ed
UPDATE privilege ON t.monitor1 TO ed
SELECT privilege ON t.monitor1 TO ed
Explanation:
The INSERT privilege ON t.monitor1 TO ED statement allows the ED to perform the IMPORT operation on
T.MONITOR1 table. The INSERT privilege also allows the users to insert data into the table.
The ALTER privilege ON t.monitor1 TO ED statement allows ED to execute the ALTER TABLE statement
on the T.MONITOR1 table. The ALTER TABLE statement allows you to add or remove constraints from the
table, add new columns to the table, increase the length of the varying-length character data type columns
in the table, and create triggers on the table.
The UPDATE privilege ON t.monitor1 TO ED statement allows ED to modify the data in the T.MONITOR1
table. This privilege can be granted either on the entire table or on selective columns in the table.
The SELECT privilege ON t.monitor1 TO ED statement allows ED to access data in the table. This privilege
also allows the users to run the EXPORT utility against the table and to create a view based on the table.

A table in the database is used to record the attendance registered during a show. The maximum capacity
of the auditorium is 10,000. The SEATS_EMPTY column displays the current number of vacant seats in the
show at any point in time.
Which two of the following could be used to automatically decrement the value of the EMPTY_SEATS
column whenever a seat is filled? (Choose two.)
…
…
;
…
;
View
Index
Trigger
Sequence
Transition variable
Explanation:
Sequences and triggers can be used to automatically decrement the value of the EMPTY_SEATS column
whenever a seat is filled during the show. You can also use the GENERATE ALWAYS AS IDENTITY clause
to generate values for columns.
You can create a BEFORE INSERT trigger on the table and use the REFERENCING clause to decrement
the value for the EMPTY_SEATS column. The trigger must be a FOR EACH ROW trigger.
A view is the result of a SELECT query on the base tables.
Indexes are pointers pointing to the rows of the base table. Indexes are used to enforce uniqueness and to
increase the performance of queries.
Transition variables are values in a set of affected rows during a triggered action. Transition variables can
refer either to old values (before the insert, update or delete operation is performed) or to new values (after
the insert, update, or delete operation is performed).

check_salary RETURNS CHAR TO MARK
check_salary(INT, CHAR) RETURNS CHAR TO MARK
Explanation:
The statement GRANT EXECUTE ON FUNCTION check_salary TO MARK will allow MARK to execute
the SELECT statement that uses the function CHECK_SALARY. The EXECUTE privilege allows the user to
invoke a routine. A routine can be a user-defined function, a stored procedure, or a method. The EXECUTE
privilege on a routine also allows the user to use the routine in a DDL or DML statement.
The statements GRANT EXECUTE ON FUNCTION check_salary(INT, CHAR)TO MARK, GRANT
EXECUTE ON FUNCTION check_salary RETURNS CHAR TO MARK, and GRANT EXECUTE ON
FUNCTION check_salary(INT, CHAR) RETURNS CHAR TO MARK are incorrect. The correct syntax of
granting the EXECUTE privilege on a function is:
GRANT EXECUTE ON FUNCTION < function name> TO < recipient> < WITH GRANT OPTION>
When granting the EXECUTE privilege on a function, neither the input parameters nor the return datatype of
the function is required.

LOCK
TABLE < table name > IN SHARE MODE
INDEX < index name > IN SHARE MODE
COLUMN < column name >IN SHARE MODE
BUFFERPOOL < bufferpool name > IN SHARE MODE
Explanation:
The statement LOCK TABLE < table name > IN SHARE MODE is a valid statement. Locking a table in
share mode for a transaction will deny other concurrent transactions from modifying data in the locked table.
However, other transactions will be able to read data from the locked table.
The statements LOCK INDEX < index name > IN SHARE MODE, LOCK COLUMN < column name
>IN SHARE MODE, and LOCK BUFFERPOOL < bufferpool name > IN SHARE MODE are not valid
because locks can only be acquired for rows, tables, and tablespaces.

The database name cannot begin with a number.
The database name can contain characters, such as @, #,_, and $.
The database name can begin with the letter sequences "SYS", "DBM", or "IBM".
The database name cannot be the same as any other database within the instance.
Explanation:
The statement the database name can begin with the letter sequences "SYS", "DBM", or "IBM" is not true.
These letter sequences are reserved words and have a special meaning for the DB2 Database. These letter
sequences cannot be used to assign a name to a database during database creation. Attempting to create a
database where the name of the database begins with "SYS", "DBM", or "IBM" will cause the CREATE
DATABASE statement to fail.
The options the database name cannot begin with a number, the database name can contain characters,
such as @, #, _, and $, and the database name cannot be the same as any other database within the
instance are true. The database name can only consist of the characters a-z, A-Z, 0-9, @, #, _, and $.
Attempting to create a database where the name of the database begins with a number or the name
matches the name of an already existing database will cause the CREATE DATABASE statement to fail.

The following statement resulted in an error when executed from the client's workstation:
DB2 CONNECT TO my_db USER user1
The following error message was generated:
SQL1013N The database alias name or database name "my_db" could not be found
Which of the following statements correctly identifies the possible reason for this error?
{
{
~
{
USER1 is not authorized to connect to the database.
The DB2 client version is not compatible with the server version.
The client's node directory does not contain an entry for MY_DB.
The database is not configured to accept incoming connection requests.
Explanation:
The possible reason for this error is that the client's node directory does not contain an entry for MY_DB. For
a client to establish a connection with the remote database, the server workstation must be cataloged in the
client's node directory. The database must also be cataloged in the system database directory of both the
client and the server.
The options stating that USER1 is not authorized to connect to the database, the DB2 client version is not
compatible with the server version, and the database is not configured to accept incoming connection
requests are incorrect. These statements will not cause the error message SQL1013N The database
alias name or database name "my_db" could not be found to be generated.

Which of the following predicate can be used in a SELECT statement to view the list of all employees that
work in either ACCOUNTS or CLERICAL department?
~
{
{
{
IN
LIKE
EXISTS
BETWEEN
Explanation:
The IN predicate can be used to view the list of all employees that work in either ACCOUNTS or CLERICAL
department. The IN predicate is used to check the existence of a value in a given set of values. The finite
set of values can either appear in the SELECT statement directly or it can appear in the subquery as part of
the main query.
The LIKE predicate is used to define a comparison relationship in which a character value is checked to see
whether or not it contains a specific pattern of characters. The underscore ( _ ) and the percent ( % ) are two
wild card characters used in pattern searching.
The EXISTS predicate is used to find whether or not a particular value exists in a given table. The query
using the EXISTS predicate must include a subquery.
The BETWEEN predicate is used to find whether or not the value of a column is within a range of values.

Dropping objects in the database
Restricting DML activity on weekends
Automatically generating values for columns
Explanation:
The action dropping objects in the database cannot be performed using triggers. Triggers are a series of
actions that are to be executed when there is an insert, update, or delete operation on the table. Triggers
cannot be used to perform DDL operations in the database.
The options invoking functions, restricting DML activity on weekends, and automatically generating values
for columns can be performed using triggers. Triggers can be used to enforce data integrity and business
rules. Triggers can also be used to update other tables, automatically generate values for columns, invoke
functions, and restrict DML activity on specified tables during specified times.

SELECT acctyear FROM accounts
UNION ALL
SELECT acctyear FROM payroll
{
{
{
~
0
6
9
10
Explanation:
The rows would be returned by the query. When using the UNION ALL set operator, the result set of each
query is combined and duplicate rows are not removed. In this scenario, each individual query will return 5
rows. This makes the total rows for both the queries as 10, including the duplicate rows. The duplicate rows
are for the values 2000 (for ACCTID 1001 and 1002) and 2002 (for ACCTID 1003).
The option 0 is incorrect because the query will return 10 rows.
The option 6 is incorrect because the query will return 10 rows. The query would have returned 6 rows if the
UNION set operator had been used instead of UNION ALL. The UNION set operator combines the result set
of each query but duplicate rows are removed. In this scenario, if UNION set operator would have been
used, the query would have removed the occurrence of the duplicate rows 1001, 1002, and 1003. Therefore,
the total would have been 6 rows (rows 2001 and 2004 from the PAYROLL table, rows 1998 and 2003 from
the ACCOUNTS table, and one row each for the values 2000 and 2002).
The option 9 is incorrect because the query will return 10 rows.

FROM employee INNER JOIN department ON dept =
FROM employee e LEFT OUTER JOIN department d ON
FROM employee e FULL OUTER JOIN department d ON
FROM employee e RIGHT OUTER JOIN department d ON
Explanation:
The SQL statement SELECT name, deptname FROM employee INNER JOIN department ON
dept = workdept will produce the desired result. This SELECT statement will produce the names of
employees from the EMPLOYEE table, along with their department name if they have a matching value in
the DEPARTMENT table. An inner join operation returns those rows from one table that have a
corresponding row in the second table.
The SQL statement SELECT name, deptname FROM employee e LEFT OUTER JOIN department
d ON e.dept = d.workdept will produce the names of the employees along with their department
name, including those employees who are not assigned a department value. When a LEFT OUTER JOIN is
performed, all rows from the leftmost table (EMPLOYEE table) of the join operation that have matching rows
in the rightmost table (DEPARTMENT table) are returned, together with all the rows from the leftmost table
eliminated by the inner join operation. In this scenario, all matching rows (WAGNER, SCOTT, PETER, and
MIKE) in these two tables will be returned with will all the non-matching rows (JONES and JOANA) in the
EMPLOYEE table.
The SQL statement SELECT name, deptname FROM employee e FULL OUTER JOIN department
d ON e.dept = d.workdept will produce the name of the employees from the EMPLOYEE table, along
with the department name if they have a corresponding value in the DEPARTMENT table. In addition, this
SELECT statement will also produce all rows in both tables that are eliminated by the inner join operation.
When a FULL OUTER JOIN is performed all rows from the leftmost table (EMPLOYEE table) of the join

operation that have matching rows in the rightmost table (DEPARTMENT table) are returned, together with
all the rows from both the tables that are eliminated by the inner join operation.
The SQL statement SELECT name, deptname FROM employee e RIGHT OUTER JOIN
department d ON e.dept = d.workdept will produce the name of the employees from the
EMPLOYEE table, along with their department name if they have a corresponding value in the
DEPARTMENT table. In addition, this SELECT statement will also produce the names of the department
from the DEPARTMENT table that are not assigned to any employee. When a RIGHT OUTER JOIN is
performed, all rows from the rightmost table (DEPARTMENT table) of the join operation that have matching
rows in the leftmost table (EMPLOYEE table) are returned with all the rows from the rightmost table
eliminated by the inner join operation. In this scenario, all matching rows (WAGNER, SCOTT, PETER, and
MIKE) in these two tables will be returned, as will all non-matching rows (ADMINISTRATIVE and
ENGINEERING) in the DEPARTMENT table.

AVG
MAX
COUNT
Explanation:
The COUNT SQL function will return the total number of employees in the EMPLOYEE table. The COUNT
function is a SQL built-in function packaged within the DB2 UDB Database. The COUNT function returns the
total number of non null values found in a table column. The column name is passed as an argument to the
COUNT function.
The SUM SQL function will return the sum of the values in a table column. The column name is passed as
an argument to the SUM function.
The AVG SQL function will return the average of the values in a table column. The average value is derived
by dividing the sum of the values in a table column by the total number of values found in that column. The
column name is passed as an argument to the MAX function.
The MAX SQL function will return the largest value found in a table column. The column name is passed as
an argument to the MAX function.

…
…
;
…
;
Indexes can be created on the table.
The table contains data that is free of constraint violations.
The table cannot be modified using insert, update, or delete operations.
The DB2 UDB utility can perform insert, update, or delete operations on the table.
The table is currently placed in Check Pending state and constraint checking is disabled.
Explanation:
The statements the table cannot be used in insert, update, or delete operations and it is currently placed in
Check Pending state and constraint checking is disabled correctly describe the state of the table. Constraint
checking on
a table can be suspended temporarily by executing the SET INTEGRITY SQL statement.
When constraint checking on a table is suspended, the table is placed in the Check Pending state and
constraint checking is disabled. However, the table may contain data that violates the constraints. During the
Check Pending state, you cannot perform any insert, update, or delete operations on the table. In addition,
any DB2 UDB utility cannot use the table to perform any insert, update, or delete operations while the table
is in the Check Pending state. You cannot create any indexes on the table while the table is in the Check
Pending state. In addition, data stored in the table can be retrieved only if the access mode specified with
the SET INTEGRITY statement allows you to do so.
The option stating that indexes can be created on the table is incorrect. You cannot create any indexes on
the table while the table is in the Check Pending state.
The option stating that the table contains data free of constraint violations is incorrect. The table may contain
data that violates the constraints.
The option stating that the DB2 UDB utility can perform insert, update, or delete operations on the table is
incorrect. DB2 UDB utilities cannot use the table to perform these types of operations while the table is
placed in the Check Pending state.

col3 DECIMAL (10,2),
CONSTRAINT fk_col1 FOREIGN KEY (col1) REFERENCES states (col1) ON DELETE
RESTRICT);
How many rows are deleted from table STATES as a result of the following DELETE statement?
DELETE FROM country WHERE col1 = "1"
~
{
{
{
0
1
2
3
Explanation:
Zero rows are deleted as a result of the DELETE FROM country WHERE col1 = "1"statement. This is
because the referential integrity constraint defined on the child table includes the ON DELETE RESTRICT
deletion rule, which will prevent rows from being deleted from the parent table when there are matching
rows in the child table. The ON DELETE RESTRICT deletion rule will ensure that the value for the foreign
key of each row in the child table will have a matching value in the parent key of the parent table, whenever
any delete operation is performed on the parent table.
The options stating one, two, and three rows are deleted from the STATES table as a result of the DELETE
statement are incorrect. The presence of the ON DELETE RESTRICT deletion rule with the referential
integrity constraint will cause the DELETE statement to fail. Therefore, no rows will be deleted from child
STATES table.

~
{
{
It catalogs a remote server named DB2_SRV.
It catalogs a remote server named DB2HOST.
It catalogs a client's workstation named DB2_SRV.
It catalogs a client's workstation named DB2HOST.
Explanation:
The CATALOG TCPIP NODE command in this scenario catalogs a remote server named DB2HOST. The
REMOTE clause identifies the host name where the remote database resides. The SERVER clause
identifies the service name or the port number that the DB2 Database Manager instance on the server uses
to communicate with. The OSTYPE clause identifies the type of operating system being used on the server
workstation. Therefore, the CATALOG TCPIP NODE command catalogs a node for an AS/400 server
workstation named DB2HOST and assign it the alias DB2_SRV. The NODE clause identifies the alias to be
assigned to the node that needs to be cataloged. This name is created on the client the node.
The option stating that the CATALOG TCPIP NODE command catalogs a remote server named DB2_SRV
is incorrect. DB2_SRV is the name created on the client to identify the node that is being cataloged.
The option stating that the CATALOG TCPIP NODE command catalogs a client's workstation named
DB2_SRV is incorrect. No information regarding the client is required while cataloging a remote server.
The option stating that the CATALOG TCPIP NODE command catalogs a client's workstation named
DB2HOST is incorrect. DB2HOST is the name of the server where the remote database resides.

Which of the following constraints will cause an index to be created by the DB2 Database Manager?
{
~
{
{
Check
Unique
Not Null
Referential
Explanation:
The unique constraint will cause an index to be created by the DB2 Database Manager, if no index exists.
Unique and primary key constraints cause the creation of unique indexes by the DB2 Database Manager.
When a unique constraint is defined on a column or group of columns in a table, the DB2 Database
Manager checks to see whether an index already exists on the columns the unique constraint refers to. If an
index already exists, then the index is marked as unique and system-required. If an index does not exist,
then the index is created and marked as unique and system-required.
Check, Not Null, and Referential integrity constraints will not cause an index to be created by the DB2
Database Manager. This is because the DB2 Database Manager implicitly creates an index for unique and
primary key constraints, by default.

Which one of the following clauses cause the SELECT SQL statement to fail?
{
{
{
~
FROM
WHERE
ORDER BY
GROUP BY
Explanation:
The GROUP BY clause will cause the SELECT statement to fail because the GROUP BY clause uses the
column alias to identify the column. You cannot use a column alias with a GROUP BY clause.
The clauses FROM, WHERE, and ORDER BY will not cause the SELECT statement to fail. These clauses
are syntactically correct.

Given the following conditions:
•
•
•
•
•
Employee identification number must be unique and required
Employee name should not accept null values
Employee phone number must be unique
Each employee must be assigned a department
Employee photograph must be included
Which of the following CREATE TABLE statements will satisfy all the conditions?
{ CREATE TABLE employee
(emp_id INT NOT NULL PRIMARY KEY,
emp_name VARCHAR(50) NOT NULL,
phone_no INT,
dept_id INT NOT NULL,
emp_photo BLOB)
{ CREATE TABLE employee
(emp_id INT NOT NULL PRIMARY KEY,
emp_name VARCHAR(50),
phone_no INT,
dept_id INT NOT NULL,
emp_photo CLOB,
CONSTRAINT chk1 UNIQUE (phone_no))
{ CREATE TABLE employee
(emp_id INT NOT NULL PRIMARY KEY,
emp_name VARCHAR(50),
phone_no INT,
dept_id INT NOT NULL,
emp_photo BLOB,
CONSTRAINT chk1 UNIQUE (phone_no))
~ CREATE TABLE employee
(emp_id INT NOT NULL PRIMARY KEY,
emp_name VARCHAR(50) NOT NULL,
phone_no INT,
dept_id INT NOT NULL,
emp_photo BLOB,
CONSTRAINT chk1 UNIQUE (phone_no))
Explanation:
The following CREATE TABLE statement satisfies all the specified conditions:
CREATE TABLE employee
(emp_id INT NOT NULL PRIMARY KEY,
emp_name VARCHAR(50) NOT NULL,
phone_no INT,
dept_id INT NOT NULL,
emp_photo BLOB,
CONSTRAINT chk1 UNIQUE (phone_no))
The PRIMARY KEY constraint defined on the EMP_ID column of the table will not allow null values. In
addition, this constraint will not allow any duplicate values. The NOT NULL constraint defined on the
EMP_NAME column will
not allow any null values. The UNIQUE constraint defined on the PHONE_NO column will allow only unique
numbers to be stored in the column. The NOT NULL constraint defined on the DEPT_ID column will ensure
that each employee is assigned a department. The BLOB data type will allow the EMP_PHOTO column to
store the employees' photographs.
The following CREATE TABLE statement does not satisfy all the given conditions:
Page 55 of 68

CREATE TABLE employee
(emp_id INT NOT NULL PRIMARY KEY,
emp_name VARCHAR(50) NOT NULL,
phone_no INT,
dept_id INT NOT NULL,
emp_photo BLOB)
This statement does not have a UNIQUE constraint defined on the PHONE_NO column. This will allow
duplicate phone numbers to be stored in the PHONE_NO column.
The following CREATE TABLE statement does not satisfy all the given conditions:
CREATE TABLE employee
(emp_id INT NOT NULL PRIMARY KEY,
emp_name VARCHAR(50),
phone_no INT,
dept_id INT NOT NULL,
emp_photo CLOB,
CONSTRAINT chk1 UNIQUE (phone_no))
This statement will not allow employees' photographs to be stored because the EMP_PHOTO column has a
CLOB data type. The CLOB, CHARACTER LARGE OBJECT, and CHAR LARGE OBJECT data types are
used to store single-byte character set (SBCS) or multibyte character set (MBCS) values that range from 32,
700 to 2, 147, 483, 647 characters in length.
The following CREATE TABLE statement does not satisfy all the given conditions:
CREATE TABLE employee
(emp_id INT NOT NULL PRIMARY KEY,
emp_name VARCHAR(50),
phone_no INT,
dept_id INT NOT NULL,
emp_photo BLOB,
CONSTRAINT chk1 UNIQUE (phone_no))
This statement does not have a NOT NULL constraint defined on the EMP NAME column. This will allow
the column to accept null values for the EMP NAME column.

A stored procedure named CALC_SALARY has been deployed on a DB2 UDB server. What is the minimum
software requirement for the client workstation to execute this stored procedure?
~
{
{
{
DB2 run-time client
DB2 administration client
DB2 personal developer's edition
DB2 application development client
Explanation:
To execute the stored procedure, the minimum software requirement for the client machine is the DB2 runtime client. The DB2 run-time client allows the client to issue SQL statements to access the data stored on
the server and allows applications using ODBC/CLI, JDBC, SQLJ, and OLE DB to both run on the client and
interact with the data on a DB2 UDB and/or a DB2 Connect server.
The remaining options are incorrect because they are not considered to be the minimum software
installation for a client.
The DB2 administration client allows the client to perform administrative operations on a DB2 UDB
database. The DB2 administration client also allows the client to connect with a DB2 UDB and/or a DB2
Connect server.
The DB2 personal developer's edition allows a client to develop, run, and test applications that interact with
the DB2 UDB databases using the following methods:
•
•
•
•
•
Embedded Structured Query Language (SQL)
IBM's Call Level Interface (CLI)
Java Database Connectivity (JDBC)
SQL Java (SQLJ)
DB2 Application Programming Interfaces (APIs)
The DB2 application development client allows a client to perform administrative operations on a DB2 UDB
database and allows the client to connect to a DB2 UDB and/or a DB2 Connect server. The DB2 application
development client also allows a client to develop, test, and run applications designed to interact with a DB2
database.

Locks are released.
No new connections are allowed.
Uncommitted changes are undone.
Database is shutdown to restore consistency.
Explanation:
The statement database is shutdown to restore consistency does not identify the effect of an unsuccessful
transaction. When a transaction is abnormally terminated, the DB2 Database Manager releases all locks
held by the transaction, rolls back all the uncommitted changes made by the transaction using the
transaction log files, and does not allow new connections to the database unless consistency is restored.

You need to grant read-only access to the RESOURCES table to all users in the database. Which of the
following conditions would allow you to grant this type of access?
~
{
{
{
You are the owner of the table.
You have been granted the PUBLIC privilege on the table.
You have been granted the SELECT privilege on the table.
You have been granted the SELECT WITH PUBLIC OPTION privilege on the table.
Explanation:
If you are the owner of the RESOURCES table, you can grant read-only access to all users in the database.
Alternatively, If you have been granted the SELECT WITH GRANT OPTION privilege on the RESOURCE
table, you can grant read-only access to all users in the database.
The option you have been granted the PUBLIC privilege on the table is incorrect. PUBLIC is not a privilege;
it is a user group.
The option you have been granted the SELECT privilege on the table is incorrect. The SELECT privilege on
the table will allow you to view the data in the table, but will not allow you to grant privileges on the table.
The option you have been granted the SELECT WITH PUBLIC OPTION privilege on the table is incorrect.
You need the SELECT WITH GRANT OPTION privilege on the RESOURCES table for granting read-only
access to all users in the database, not the SELECT WITH PUBLIC OPTION privilege.

{ Data Warehousing cleans and transforms data for end-user decision making.
{ Data Warehousing allows users to query the warehouse without affecting the operational
databases.
~ Data Warehousing performs calculations on the operational data and writes the summarized data to
the operational database.
Explanation:
The statement Data Warehousing performs calculations on the operational data and writes the summarized
data to the operational database is not true. Data Warehousing performs calculations on the operational
data, summarizes the data, and writes the summarized data to a separate database.
The option stating that Data Warehousing extracts data from operational data is true. Data Warehousing lets
you create and maintain informational data. Informational data is extracted from the operational database
and then cleansed and transformed for end-user decision making.
The option stating that Data Warehousing cleans and transforms data for end-user decision making is true.
Data Warehousing cleans and transforms the data extracted from operational data for end user decision
making.
The option stating that Data Warehousing lets you query the warehouse without affecting the operational
databases is true. Data Warehousing performs calculations on the operational data and writes the
summarized data to a separate database. End users query this separate database (warehouse) without
affecting the operational databases.

You need to deploy an application that will access a DB2 UDB database over a Local Area Network (LAN).
The database is located on a Solaris server. The OS/390 or OS/400 based clients will access the database
using a set of transmission protocols.
To deploy the application and allow access to the DB2 server, which of the following is the minimum
software requirement for the server?
{
{
{
~
DB2 Connect Enterprise Edition
DB2 UDB Workgroup Server Edition
DB2 UDB Enterprise Server Edition and DB2 Connect Enterprise Edition
DB2 UDB Workgroup Server Edition and DB2 Connect Enterprise Edition
Explanation:
In this scenario, the minimum software requirement for the server for deploying the client application is the
DB2 UDB Workgroup Server Edition and DB2 Connect Enterprise Edition installations. DB2 UDB
Workgroup Server Edition is a client-server database management system and can run on a variety of
operating systems, including AIX, HP-UX, Solaris, Linux, Windows NT, Windows 2000, and Windows XP.
The DB2 UDB Workgroup Server Edition allows remote clients to access databases on the server. DB2
Connect Enterprise Edition (EE) is an add-on product for the DB2 UDB and provides direct connectivity
between Linux, UNIX, and Windows workstations and mainframes/iSeries database servers.
The option stating DB2 Connect Enterprise Edition only is incorrect because you need to install an edition of
DB2 UDB before using DB2 Connect.
The option stating DB2 UDB Workgroup server is incorrect because DB2 Connect Enterprise Edition
provides connectivity between the Solaris server and the OS/390 or OS/400 clients. To ensure connectivity,
both DB2 Connect and DB2 UDB Workgroup must be installed on the DB2 server.
The option stating DB2 UDB Enterprise Server Edition is incorrect because the scenario calls requires the
minimum amount of software installation. A Limited version of DB2 Connect Enterprise Edition is included in
the DB2 UDB Enterprise Server Edition. Therefore, there is no need to separately install DB2 Connect with
DB2 UDB Enterprise Server Edition.

Which of the following correctly identifies the result of creating a unique index on the HOURS column?
{
{

{
The index will be created successfully as each value is different.
The index will be created successfully if the column is marked as not null.
The index will NOT be created successfully as there are multiple null values.
The index will be created successfully if the column already has a unique constraint.
Explanation:
The index will not be created successfully as there are multiple null values. Unique indexes only allow a
single occurrence of a value in the column list. Unique indexes allow a single null value to be present in the
column list. However, presence of a second null value would cause a duplicate in the column list and is not
allowed. Unique indexes enforce uniqueness on the column values and do not allow any duplicate values.
The option the index will be created successfully as each value is different is incorrect. If there would have
been a single null value in the column and no duplicate values, the unique index would have been
successfully created.
The option the index will be created successfully if the column is marked as not null is incorrect. This is a
rule for successfully creating a unique constraint and not unique indexes. Unique indexes allow a single null
value to be present in the column on which they are defined.
The index will be not be created successfully if the column already has a unique constraint. The DB2
Database Manager automatically creates a unique index for a column having a primary key or a unique
constraint if no index already exists. You cannot create additional unique indexes on columns having
unique or primary key constraints.

In this scenario, the CONNECT, CREATEIN, and ALTERIN privileges should be granted to the user
SCOTT. The CONNECT privilege will allow the user SCOTT to establish a connection to the database. The
CREAETIN schema privilege will allow the user SCOTT to create objects within his schema and the
ALTERIN schema privilege will allow the user SCOTT to alter objects within his schema.
The CREATEIN, ALTERIN, DROPIN privileges should not be granted to the user SCOTT. The requirement
states that the user SCOTT should not be able to drop any objects from his schema. The DROPIN schema
privilege will allow the user SCOTT to drop any objects from his schema. Without the CONNECT privilege,
the user SCOTT will not be able to connect to the database.
The CONNECT, ALTERIN, DROPIN privileges should not be granted to the user SCOTT. The requirement
states that the user SCOTT should not be able to drop any objects from his schema. The DROPIN schema
privilege will allow the user SCOTT to drop any objects from his schema. Without the CREATEIN privilege,
the user SCOTT will not be able to create any objects within his schema.
The CONNECT, CREATEIN, DROPIN privileges should not be granted to the user SCOTT. The

JAN is the owner of the DEPARTMENT table. As the SYSADM, you revoke the CONTROL privilege on the
DEPARTMENT table from JAN. What is the effect of revoking the CONTROL privilege?
{

{
AII the table privileges are revoked from JAN.
JAN Ioses the ability to drop the table from the database.
JAN Ioses the ability to drop indexes created on the table.
JAN Ioses the ability to grant or revoke the CONTROL privilege to other users.
Explanation:
Revoking the CONTROL privilege on the DEPARTMENT table, will cause JAN to loose the ability to drop
the table from the database. The owner of the table is automatically granted the CONTROL privilege along
with all other privileges on that table.
When the CONTROL privilege is revoked from the owner, all other privileges are not revoked.
The CONTROL privilege on the table enables the user to drop the table from the database and grant or
revoke all other table privileges to other users and groups in the database.
Revoking the CONTROL privilege on the table does not revoke all other table privileges from the owner. AII
other table privileges must be explicitly revoked from the user.
Users can drop an index from the database if they have the CONTROL privilege on the index. The owner of
the index automatically receives the CONTROL privilege on the index. Revoking the CONTROL privilege on
the table does not have any effect on the ability of the user to drop the index from the database.
Only the users with the SYSADM or DBADM authority can revoke or grant the CONTROL privilege on any
object in the database. The owner of the object is not allowed to grant or revoke the CONTROL privilege to
other users or groups in the database.

on the DEPARTMENT table and Transaction B attempts to acquire an Exclusive (X) Iock on the
EMPLOYEE table.
Which one of the following statements regarding the deadlock situation is true?
{ Both of the transactions should release the Exclusive (X) Iock on the tables by performing a rollback

{ Transaction B should release the Exclusive (X) Iock on the table DEPARTMENT by performing a
rollback or commit operation.
~ Neither of the transactions will be able to release the Exclusive (X) Iock on the tables by performing
a rollback or commit operation.
Explanation:
The statement neither of the transactions will be able to release the Exclusive (X) Iock on the tables by
performing a rollback or commit operation is true about the deadlock situation. If the requesting transaction
Page 66 of 68
Information Management
Certification Sample Test 700 IBM DB2 UDB V8.1 Family Fundamentals (with Explanations).
is unable to acquire a lock, the transaction undergoes a lock-wait event. During the lock-wait event, all
processing by the transaction is suspended. In this scenario, both the transactions will be suspended unless
either of the transaction releases the Iock by performing a rollback or commit operation. Neither of the
transactions can release the lock by performing a rollback or commit operation because the processing is
suspended. This is known as the deadlock situation.
The DB2 Universal Database has a background process known as the deadlock detector, which is used to
resolve deadlock situations. The deadlock detector wakes up periodically to examine the locking system and
detect deadlocks. If a deadlock is detected, the deadlock detector process randomly selects one of the
transactions, rolls back all the changes, and terminates the transaction. The transaction selected by the
background process receives an SQL error code and all the locks held by the transaction are released.

Which of the following statements will allow all database users to query data in the ATHLETICS table?
{
~
{
{
GRANT ALTER ON athletics to PUBLIC
GRANT SELECT ON athletics TO PUBLIC
GRANT CONTROL ON athletics TO PUBLIC
GRANT ALL PRIVILEGES ON athletics TO PUBLIC
Explanation:
The statement GRANT SELECT ON athletics TO PUBLIC will allow all users in the database to read or
query the ATHLETICS table. The SELECT privilege also allows you to run the EXPORT utility against the
table.
The statement GRANT ALL PRIVILEGES ON athletics TO PUBLIC will grant all the table privileges to all the
users in the database, which is not the requirement in this scenario.
The statement GRANT CONTROL ON athletics TO PUBLIC will grant all the table privileges along with the
ability to drop the table from the database to all users. The CONTROL privilege can only be granted or
revoked by users who have the SYSADM or DBADM authority.
The statement GRANT ALTER ON athletics TO PUBLIC will grant the privilege to alter the table and not
select from the table. You need to alter the table if you need to add or remove constraints from the table,
add new columns to the table, increase the length of the character data type columns of the table, and
create triggers on the table.
