I'm breaking one gigantic query into several temporary tables and, then I'll join those and then do a select. Is there anything I should watch out for? Also, what are some other good methods to reduce gigantic queries into manageable amounts? Matt -- W. Matthew Wilson matt@tplus1.com http://tplus1.com

It depends on what you want. Speed? To easily manage query SQL? Here we don't use temporary table but table-returning SQL procedures (not plpgsql, just plain sql) and then do something like: SELECT * FROM procedure1(customer_id, date) A, procedure2(...) B WHERE A.id = B.id ... and so on. federico -- Federico Di Gregorio federico.digregorio@dndg.it Studio Associato Di Nunzio e Di Gregorio http://dndg.it The number of the beast: vi vi vi. -- Delexa Jones
