Last month, in "More on the RUNSQL CL Command," we saw how to select specific records from the SAMPLE database using the RUNSQL command. In that article, we hardcoded the selection criteria of Effective date (EffDate) being earlier than May 1, 2012.

This will include the ability for the user to also ignore (that is, not select on) any one or more of these three fields/columns.

Polling during the Webinar indicated that 10 percent of respondents had experienced an automatic IPL because their disk had become full.
