Re: Subset Query Speed Help from .46 second to 7 minutes!
Posted by: Brian Pilati

Felix,

I think I see something in the combined query from the Explain <query> \G results. MySQL is running the subset query first and then the query. However, the subset is dependant on the results from the query. Thus, increasing the query time.

That is what I see, anyway.

Is there any way, without rewriting the queries, to have MySQL run the query first and then the subquery?

Thanks
Brian
