Introduction to Structured Query Language
Version 3.53

jhoffman@one.net.Introduction
This is a tutorial of the Structured Query Language (also known as SQL) and is a
pioneering effort on the World Wide Web, as this is the first comprehensive SQL
tutorial available on the Internet. SQL allows users to access data in relational
database management systems, such as Oracle, Sybase, Informix, Microsoft SQL
Server, Access, and others, by allowing users to describe the data the user wishes to
see. SQL also allows users to define the data in a database, and manipulate that data.
This document will describe how to use SQL, and give examples. The SQL used in this
document is “ANSI”, or standard SQL, and no SQL features of specific database
management systems will be discussed until the “Nonstandard SQL” section.
