I need a document with examples on sql
tuning.
Does anybody have it?
I am putting the smallest tables at the beginnings
and large ones at the ends of the Where claouse of query. And I am carefull of
using columns order due to the order of primary key indexes's column order BUT
query never use any of my index...
Why ?
Thanks to all..
