Topic: SQL Server Statistics: The Secret Sauce

Learning how to write a query is a basic SQL skill. Eventually, a curious developer wants to know how SQL actually returns the data. Statistics are the “secret sauce” that SQL uses to create a query plan to get your data. In this session, the basics of how SQL creates and maintains statistics will be discussed, and the impact that the this has on query plans. Other topics covered will be what happens when statistics are wrong (and how that can happen), as well as when to take statistics maintenance into your own hands.
