Yes I knew, I wrote "clean workaround" :-)
I hate write in function piece of code like this:
~ [...]
~ my_stm := ''SELECT '' || my_operation || ''( '' || a_id_transaction; ~ my_stm := my_stm || '', '' || a_id_contract; ~ my_stm := my_stm || '', '' || quote_literal(a_date) || '') AS res'';
~ FOR my_record IN EXECUTE my_stm LOOP ~ IF my_record.res < 0 THEN ~ RETURN my_record.res; ~ END IF;
~ EXIT; ~ END LOOP;
~ [...]
note also that useless loop that is needed to retrieve the value!
