Re: Running OS commands from SQL

That version of qcmdexc is a procedure. Very cool, of course.

Even cooler might be the UDF (scalar function) version IBM have provided - this lets you use qcmdexc() as a column in the column list of a SELECT - and you can build the command from other columns in the statement, and the command will be run for each set of values. It returns a 1 if successful.

It's available for 7.3 and 7.4 - here's a link that will lead to more info - https://www.ibm.com/support/pages/qsys2qcmdexc

An example to whet your appetite -

Hold any jobs that started running an SQL statement more than 2 hours ago.
SELECT JOB_NAME, CASE WHEN QSYS2.QCMDEXC('HLDJOB ' CONCAT JOB_NAME) = 1 THEN 'Job Held' ELSE 'Job not held' END AS HLDJOB_RESULT FROM TABLE (QSYS2.ACTIVE_JOB_INFO (DETAILED_INFO=> 'ALL')) WHERE SQL_STATEMENT_START_TIMESTAMP < CURRENT TIMESTAMP - 2 HOURS;

Cheers

There's a version in QSYS2 for that

call qsys2.qcmdexc('........');

Brain Fart!

I'm drawing a blank and I can't find my old examples since I changed jobs.

In SQL you can execute commands by specifying CALL QCMDEXEC( '<command to run>' , <length of command string>)

But there is another way to do it which doesn't require the length parameter.

What is it?

Regards,
Steve
