We're not so much concerned about why temp tales are being created,
although maybe we should be, but why temp tables are having to be
written to disk. Temp tables are initially created in memory and only
written to disk if they become too large, correct?
Queries that use group bys and sort bys will create temp tables,
regardless of index usage, correct? If so, then that would explain
most the the temp table creation for our installation.
Thanks for the reply,
