Lesson 4: Optimize a Query Using the Sybase IQ Query Plan
In this chapter, you will learn how Sybase IQ executes queries, and how to interpret the Sybase IQ query plan. The focus will be on query optimization on a single IQ server, not distributed query processing in a Multiplex. That is addressed in another lesson, “Scaling Out with Multiplex and Distributed Query Processing”. In this lesson, you will execute a SQL query, and perform some analysis to optimize the query.
