I have a mysql table called update_date, the workflow uses this to recalculate everything after that date, when I push the updated results back into the table I want to run a pre SQL delete to remove the existing entries after that date and replace with the newly recalculated ones.
The update date changes, so I can't use a workflow constant. Is there a way to do this without having to completely write all the entries back to the table? And only write the updated ones back?
