Summary
This chapter covered different ways to break queries into smaller functional parts and the advantages and disadvantages of each approach. It covered the potential pitfalls of one often-used optimization toolâtemporary tablesâand showed how common table expressions can be used as an alternative that doesnât stymie the query optimizer. It also discussed views and materialized views and their impact on performance. Finally, it briefly addressed partitioning and parallel execution.
