SQLCMD – A Better DBACCESS? Utility by Jonathan Leffler Presented by Joe Kennedy ([email protected]) (301-803-1974) Sqlcmd as a SQL Command Interpreter DDL ● DML ● Select, Execute Procedure ● What is it? SQLCMD is an SQL Command Interpreter for Informix databases. It is analogous to the Query-Language option of DB-Access or ISQL, but it is designed to work better in shell scripts. SQLCMD is written in ESQL/C. It works with any version of ESQL/C from 5.00 (circa 1990) upwards. SQLCMD has a history mechanism that allows you to review, edit and rerun commands you ran previously. Alternative Output Formats ● ● ● ● ● Quote CSV XML Fixed Unload (default) -F from the command line! Load & Unload Statements ● Same Syntax as in DBACCESS or ISQL ● No transaction management in load (add your own begin work/commit statements) Reload Statement ● Syntactically similar to load statement automatically initiates transactions, groups the inserts, groups the inserts into smaller transactions if there are many rows to be loaded Info system INFO DATABASES; stores_demo@ids_joe sysmaster@ids_joe sysuser@ids_joe sysutils@ids_joe INFO CONNECTIONS; ... INFO TABLES; ... SQLunload ● ● Extract data from the database and produces ASCII output suitable for dbload or LOAD command. The database (-d) and table (-t) are always specified on the command line. Sqlreload ● ● ● The inverse of Sqlunload “Passing resemblance” to the Informix dbload utlity. Database (-d) and Table (-t) are always designated at the command line using flags. I/O Redirection Unix/Linux redirection applies echo “select * from customer” | sqlcmd -d stores_demo -F XML Contexts ● ● ● ● ● ● ● ● ● ● ● ● Level: 1 /dev/stdin Output: /dev/stdout Date: mm/dd/yyyy Escape: '\\' EOR: '\n' Query limit: 0 Input Base: 0 XML Record Tag: RECORD <BOS> Heading: <TOS> off <BOS> Continue: <TOS> off <BOS> Trace: <TOS> off <BOS> Verbosity: <TOS> off <BOS> Input: Error: /dev/stderr Delimiter: '|' Quote: '\"' History size: 50 Transaction size: 1024 BlobDir: /tmp Format: <TOS> select History: <TOS> off <BOS> Silence: <TOS> off <BOS> Types: <TOS> off <BOS> Benchmark: <TOS> off <BOS> Command line options Try “sqlcmd -help” Basic flags: -d database -f FILE -e 'SQL Statements' How do I get the Source Code? The International Informix User Group! www.iiug.org – check the software repository... distributed as a gzipped tar file with the extension ".tgz" Compilation.... SQLCMD is written in ESQL/C, you must have ESQL/C or ClientSDK on your machine before installing SQLCMD. On Unix systems (including Linux), the normal sequence of events is: ./configure LD_LIBRARY_PATH make make install
