Re: How to Undo an SQL Insert

This is a wild suggestion that will probably be of no help at all.

Would a (physical) file trigger offer a solution? (Whether External or SQL.) You could use CHGPFTRG or ALTER TRIGGER to enable/disable as required. The Trigger Buffer would contain the RRN of the successful insert/after.

HTH,
Brian.

The legacy ERP does not have ANYTHING journaled... the transaction files do not have a unique key on the PF or LF.

I understand what everyone is saying about journaling. No convincing needed. But I cannot simply "turn it on" and risk messages all over the given all the other programs that touch this file.

I'm also concerned about service program procedures (in the same module even) that have COMMIT=*NONE. I'm not sure how to handle that.

If I was certain I could turn journaling on for this file, without creating a host of other issues, I would.
