I want to write a stored proc to insert some data in a table...but before that I want to check whether that record is already present in table or not. If yes then it should display some message like "duplicate data"

I am inserting the data from front end.

And also how to catch that msg in front end.

Please help me.

Thanks in advance.

Solution 1

Well, based on the issue:
1. One of the good ways would be to put unique constraint on the table itself! It will check before inserting.
2. If you want to do it in UI, then get all data and check in a loop. But that would be a lengthy procedure.

Option1 is good for you.

UPDATE:
Look here: MSDN - UNIQUE Constraints[^
