Subj:   Re: Statistic collection questions
 
From:   Mishra, Tapas

You can decide the stat collection frequency based on the following criteria

1. The row count change (# of rows)

2. Number of unique values changing


If it's a static table then you don't need to collect frequently. Also other than primary and secondary indexes, you should collect stat on columns used in the join conditions.


Hope this helps.
