Abstract

You may not be familiar with the term subquery factoring. Prior to the release of Oracle 11gR2, the official Oracle documentation barely mentions it, providing just a brief synopsis of its use, a couple of restrictions, and a single example. If I instead refer to the WITH clause of the SELECT statement, you will probably know immediately what I mean as this term is more recognizable. Both terms will be used in this chapter.
