That doesn't sound like something I'd expect to cause a problem. 1. Is it possible that the index isn't useful for the plans you have been considering? 2. Have you run ANALYZE on the table recently? If not, it may have poor statistics that are leading it to not consider using the index. -- "cbbrowne","@","cbbrowne.com" http://linuxdatabases.info/info/x.html "Another of Fortran's breakthroughs was the GOTO statement, which was a uniquely simple and understandable means of structuring and modularizing programs." -- Article on Backus' "Draper Prize"
