Sorry for the repost, but I do really need a solution/address for this problem...

FB RC2, IBO Fr, Win2000sp1
I've a query with a join upon a stored procedure. Everything is ok since the result set is not empty. If the condition of the where clause is so that an empty result set would be returned, the following error appears:
ISC ERROR CODE:335544348
no current record for fetch operation
the problem is related to the stored procedure SEL_CODICI_CONTABILI join, that is a simple for select ... union ... into .. suspend. Is something wrong with the query or with the stored procedure?
How can I avoid the error in such a situation?
