The LDS Church is looking for DBA's. You do have to be a Church member in
good standing. A lot of kind people write me, concerned I may be breaking
the law by saying you have to be a Church member. It's legal I promise! :-)

But that won't actually raise an error, will it? Just cause 0 rows to be deleted.

How about using the where clause:
delete from duplicate where duplicate_id=1 and 0=1;
So the statement is fundamentally correct except for the last predicate.

How do I make a correct DELETE statement fail? I have a developer that wants to test a code branch and he needs a delete statement to fail.
It can’t be locked ( shared or exclusive ) from a separate session or be an incorrect statement or return “0 rows deleted.”
It has to be “delete from table where col = value”. How can I force that to fail?
thanks.
