Enhance QCMDEXC Scalar function to process an entire result set

I have hit a max limit on the QCMDEXC scalar function. for example, I have 243 jobs in the job scheduler and I need to hold them all with the exception of a few. I have to run my HLDJOBSCDE command using the qcmdexc scalar function about 3 times before it catches it all.
Another example is in our EDI library, we have thousands of EDI generated emails and as a part of the cleanup, we have to wipe them out. I had to create a loop and use the QCMDEXC procedure to solve that problem. It would be wonderful if the QCMDEXC scalar function could either be enhanced that you could tell it how many rows to process (so you dont have a super long running query) or the developer will just take the performance hit and you let the function run everything in the result set - no matter its size.

    Thank you for confirming that this request is not valid, but due to the default ACS configuration. Declining Idea to close it out.

    I don't think you have hit the QCMDEXEC scalar function max limit.

    It sounds like you are using ACS "Run SQL script" to execute these statements and ACS retrieves 100 rows be default.

    This means that the QCMDEXEC scalar function only process 100 times before it stops, you can then click the icon that looks like a download button at the right lower side to execute the rest.

    Another approach, if you are on the latest ACS version, is to configure another number than 100:

    From the "Run SQL script" screen, select "Edit" > "Preferences..." and the "Results" tab and change "Number of rows to retrieve at a time" to a number that suits your needs.
