Hello all,

I am a bit confused...I have a database which was performing very POORLY
selecting from a view (posted earlier) on one server but extremely fast on
another server...

I just backed up the database from the FAST server and loaded to the SLOW
server and it ran just as fast as it originally did...my questions are:

Are STATISTICS some how saved with the database??  if so, how do I UPDATE
view or update them?

Should I backup the data \ drop the database and reload it to make it get
new stats?? (vacuum analyze does nothing for this poor performing database)

Thanks-a-bunch.
