Re: Where Clause Performance

MySQL SPs rarely improve query performance. If the app language is running on the same sever as the DB, the diff is miniscule at most. On a distant server, mebbe it cvould become significant, but if that's so, it may be time to move one of them.

Most query execution time goes to scanning tables & indexes and assembling the result, and there the SP rarely improves performance.

A rule of thumb: do it where it's most convenient and where you'll just have to write it once.
