Carol,

<< I am using IB Expert personal edition and when I try to compile de SP, an

I don't know if that's an IB Expert problem or what.

I use Database Workbench (an awesome product) and this:

SELECT 1 FROM rdb$database WHERE EXISTS
(SELECT 1 FROM CAREGIVERS WHERE ID = 0)

works fine for me in the script editor. In the above case, I get an empty
result set, because my lowest ID val in that table is 2. If I change the "="
to a "<>", I get a result of "1".
