Hence the cycle of performance tuning is longer. Regarding "real time analysis" what I understand is EXPLAIN ANALYSE (of main SQL using the function) in postgresql cannot provide the realtime analysis of the performace of queries inside the function. probably such a limitation may exists in db2 also.

I was told that, for DB2, stored procedures are a better choice for parameterized views which is what I was trying to do with the functions. Is the same true for PostgreSQL? -Aaron -- ================================================================== Aaron Bono Aranya Software Technologies, Inc. http://www.aranya.com http://codeelixir.com ==================================================================
