Subj:   Re: EXPLAIN cost estimates

The fact that it says no confidence is indication that statistics have not been collected. I look through my explains for this text and low confidence to see if there is anything I can do to to increase the confidence by changing the way I wrote the query. When it says high confidence then it used statistics.
