Left Join outperforming Inner Join?

Question

I\'ve been profiling some queries in an application I\'m working on, and I came across a query that was retrieving more rows than necessary, the result set being trimmed dow

Answer 1

imo you are falling into the pitfall known as premature optimization. Query optimizers are insanely fickle things. My suggestion, is to move on until you can identify for sure that the a particular join is problematic.
