Hi,
I'm trying to get an answer from a dynamic query using perform. The
problem is that it sets the FOUND variable to true even when performing
bogus queries.
Am I missing something here? The documentation says that PERFORM only
sets FOUND to true if it finds and discards a row but doing something like:
qry := 'SELECT notafield FROM notatable'
PERFORM qry
Also sets FOUND to true, even more using a query like 'BLABLABLA' also
set found to true.
What am I doing wrong here?
Thanks for any help in advance,
Martin

I think you are looking for EXECUTE, not PERFORM. The above only
confirms that indeed "qry" is a scalar variable --- its contents
are not examined.
