validation rule : check for overlapping dates
110997Oct 20 2006 — edited Jun 28 2007hi,
I have 2 columns, a start date and and end date, I want to create a validation rule that will check if the above columns in a new or updated row does not overlap with any other record in the table. How do I do that?
I've already implemented a validation rule that checks if the start date is earlier than the end date and it works fine.
Thanks,
