Calling an AS/400 Program with QCMDEXC
Last Update: 04 June 2014
Version: 5.x, 6x
Article ID: SQV00SQ040
You can execute a program on the AS/400 using the program QCMDEXC.
For example, if you have a program called MYPGM that you want to execute, you could send this SQL statement to the AS/400:
CALL QSYS.QCMDEXC('CALL PGM (MYLIB/MYPGM)', 0000000022.00000)
You can also enable additional messages to be logged on the AS/400 joblog by running this command:
CALL QSYS.QCMDEXC('STRDBG UPDPROD(*YES)',0000000020.00000)
The second parameter is the number of characters, including spaces between the single quotes in the STRDBG UPDPROD(*YES) command, which in this case is 20.
Note: The second parameter must contain exactly 15 digits: ten to the left of the decimal and five to the right. (If you are building a custom application, you can write a module to count the length of the command and create the second parameter for you.)
The procedure must be registered; otherwise StarSQL will return the error:
[StarSQL][StarSQL ODBC Driver]Column not found.
To register it, execute the following SQL statement on the AS/400:
CREATE PROCEDURE QSYS.QCMDEXC(IN :CMDSTR VARCHAR(1024),IN :CMDLENGTH DECIMAL(15,5)) EXTERNAL NAME QSYS.QCMDEXC LANGUAGE C GENERAL
For more information, see Sample
SQL for Registering a Stored Procedure on the AS/400.
Please reference the IBM Book OS/400 CL Programming, Advanced Programming Topics that pertains to your specific AS/400 version.
