Abstract

During the first step of query processing, the parser extracts the relevant data from an SQL statement. The next step, called planning, is to turn that data into a relational algebra query tree. This chapter examines the basic planning process. It examines what the planner needs to do to verify that an SQL statement is semantically meaningful and looks at two rudimentary plan-construction algorithms.
