Re: Composite index - selecting components and order

I'm just finishing a restructure where i have a new table holding my GROUP BY structure, removing that from the equation most times.

I've also restructured so that the ORDER BY is also rarely used.

So I really need to concentrate on optimizing indicies for the SELECT and WHERE items. And yes, there are most usually a significant number of items in the IN clauses.

I'll look into the bulk of your suggestions tomorrow when I have a chance to really look at them.

Thanks for any input.
