hi, there, I use two serial type fields within one table, seems psql does not like it: it override the first one with the second one! Why? (seems to me quite often if I do not want to normize it too much) or something else? here is the table: create table tmpschedule ( schedid serial, addtime datetime, eventid serial, eventaddtime datetime, poll int ); thanks in advance!!! ______________________________________________________ Get Your Private, Free Email at http://www.hotmail.com ************
