Subject: advice on query joining 10 tables
Date: Mon, 10 May 2010 15:40:12 -0300
Message-ID: <4BE8530C.6030605@fmed.uba.ar> (raw)

Hi all. Im triyng to see if i can improve the performance of a query
(mainly a 10 table join)

1) Besides of triyng to use indexes, there is some rules of thumb to follow?

2) Should i try to join the bigger tables last in the query?

3) There is some place for understanding EXPLAIN better?

Thanks!
Gerardo
