Скачать или смотреть Exploring Microsoft SQL Server Query Execution Plans - Drew Furgiuele

Okay, your SQL query is slow. But why? In this session, we'll cover the basics of Microsoft SQL Server query execution plans: What plans are, how to read them, and why you should care about them even though you're not a DBA. Along the way you'll also see plenty of examples of plan operations, how plans can go wrong, and how you can quickly fix them yourself. You might even see some neat query plan features coming in future editions of SQL Server that should get you excited, too!
