The 'dumb' thing is that this list doesn't allow attachments, Gordon. So extract the text of the stored procedure (and possibly some table create and insert if required) and post it to this list (strip out parts that are irrelevant for your question, we don't want an SP of several thousand lines).

If your SP looks something like:

create MySP returns(a integer = ?) as
a = (select coalesce(MyVariable, 0) from MySingularTable);
update or insert into MySingularTable(MyVariable)
values(gen_id(MyGenerator, 1));

then this will of course return <null> if MySingularTable is empty (there's no row to select, so coalesce is not executed). Though I don't know whether your problem is similar to this or something completely different.
