Chapter 14: Query Processor

This chapter describes the new features of the Microsoft SQL Server query processor. The query processor is that portion of SQL Server that accepts, parses, and executes SQL syntax. This chapter includes these topics:

• Query processor goals
• Query execution
• Query optimization
• Distributed queries
• Working with queries

The query processor is closely related to the storage engine, another part of SQL Server. For more information, see "Storage Engine" later in this volume.
