This chapter provides an overview of how to useSQL to perform simple operations. This tutorial is only intended to give you an introduction and is in no way a complete tutorial onSQL. Numerous books have been written onSQL, including[melt93] and[date97]. You should be aware that somePostgres Pro language features are extensions to the standard.

In the examples that follow, we assume that you have created a database namedmydb, as described in the previous chapter, and have been able to startpsql.
