Question

I have a stored procedure that first inserts some data into a temp table and then inserts a row into another table. I am calling Scope_Identity() after the second insert to pick up the newly inserted record Identity.

If the second insert does nothing due to a join, I want to check the Scope_Identity and raise an exception. But Scope_Identity is returning the last identity created from the temp table insert before the second insert.

Is there a way to reset SCOPE_IDENTITY before calling the second insert, or a better way to determine if the second insert didn’t actually insert anything?

Answer 1

Check @@ROWCOUNT immediately after the 2nd insert. If it is 0 then no rows were inserted.

INSERT INTO YourTable
SELECT ...

IF (@@ROWCOUNT = 0)
BEGIN
RAISERROR('Nothing inserted',16,1)
RETURN
END
