Chapter 3. PostgreSQL SQL Syntax and Use

The first two chapters explored the basics of the SQL language and looked at the data types supported by PostgreSQL. This chapter covers a variety of topics that should round out your knowledge of PostgreSQL.

We'll start by looking at the rules that you have to follow when choosing names for tables, columns, indexes, and such. Next, you'll see how to create, destroy, and view PostgreSQL databases. In Chapter 1, "Introduction to PostgreSQL and SQL," you created a few simple tables; in this chapter, you'll learn all the details of the CREATE TABLE command. I'll also talk about indexes. I'll finish up by talking about transaction processing and locking. If you are familiar with Sybase, DB2, or Microsoft SQL Server, I think you'll find that the locking model used by PostgreSQL is a refreshing change.
