Just not for the original reasons I thought they wouldn't be an option at all. Since most queries ask for both types, and that's practically the whole table, any index with a filter would not really be any better than the same index without one.

Unfortunately, the data skew in the Posts table is almost 100% Questions and Answers: For a filtered index to be worthwhile, it has to be relatively narrow and it has to eliminate a lot of rows. Not confusing or inconsistent at all.Īnyway, it was all for naught. At least if PostTypeId is the leading key if not, that falls apart. WHERE PostTypeId >= 1 AND PostTypeId = 1 AND PostTypeId = 1 AND PostTypeId <= 2.
