Query optimizer is a magical piece of architecture inside SQL Server which instructs the engine how your query is going to be executed. It performs a great job …unless it doesn’t.

In this session we will have a deep look on cases where the query optimizer fails and explain why is it happening. Expect to see a real code written by real developers which will be tuned just in front of you to perform several times faster. If you want to (or possibly need to) take control of execution plan, this session is right for you!
