SQLTUL Tool - Unloading SQL Tables

Attention: This topic applies to a feature that is in Early Adopter Program (EAP) release status. We intend to provide the finalized feature in a future release. Please contact Micro Focus Customer Care if you require further clarification.

The SQLTUL tool is equivalent to DB2 DSNTIAUL. It is used unload some or all rows from up to 100 tables in one JCL step. With SQLTUL, you can unload data of all built-in data types except LOB and time-interval types. The format of unload data is compatible with SQLUTB LOAD utility and the load control statements are generated during the unload process. The unload data is encoded in ASCII character set as the default and in EBCDIC character set as optional.

You can also use SQLTUL to execute SQL non-SELECT statements dynamically.

Note: As part of the environment setup, SQLTUL initializes the ALLOWNULLCHAR SQL compiler directive option to preserve the X"00" null character in CHAR and VARCHAR fields. See ALLOWNULLCHAR in the Enterprise Developer documentation for details.

SQLTUL supports a number of popular RDBMSs via the OpenESQL runtime, including SQL Server, DB2 LUW, Oracle, and PostgreSQL. When running against a specific RDBMS, the SQL dialect of the SELECT statements used in SQLTUL should be native to the RDBMS. For example, when targeting SQL Server, use the T-SQL dialect.

The following is an example of JCL using SQLTUL:

//UNLOADTL  JOB
//RESETDB  EXEC PGM=IKJEFT01
//SYSTSPRT DD  SYSOUT=*
//SYSPRINT DD  SYSOUT=*
//SYSREC00 DD  DSN=MCS.UNLOAD. UNLOADTL,
//             UNIT=SYSDA,SPACE=(CYL,(1,1)),DISP=(MOD,CATLG),
//             VOL=SER=SCR03,RECFM=FB
//SYSPUNCH DD  DSN=MCS. UNLOADTL.SYSPUNCH,
//             UNIT=SYSDA,SPACE=(CYL,(1,1)),DISP=(MOD,CATLG),
//             VOL=SER=SCR03,RECFM=FB
//SYSUDUMP DD  SYSOUT=*
//SYSOUT      DD  SYSOUT=*
//SYSTSIN      DD  *
 DSN SYSTEM(HCOD)
 RUN  PROGRAM(SQLTUL) PARMS('SQL,250') 
//SYSIN       DD  *
SELECT * FROM MFIXCH.EMP;
/*

Where HCOD is the ODBC XAR ID for your database connection.

Parameters

The following parameters are supported by SQLTUL:

SQL
TOLWARN
EBCDIC (specifies that the dataset is encoded in EBCDIC)

SQLTUL ignores parameters that indicate the number of rows per fetch, and ignores the LOBFile parameter.
