Wikibooks SQL Tutorial - SQL Query Reference and Programming Examples SQL (Structured Query Language) is a computer language aimed to store, manipulate, and query data stored in relational databases. The first incarnation of SQL appeared in 1974, when a group in IBM developed the first prototype of a relational database. The first commercial relational database was released by Relational Software (later becoming Oracle). Standards for SQL exist. This SQL programming help site lists commonly-used SQL statements, and is divided into the following sections: SQL Commands: Basic SQL statements for storing, retrieving, and manipulating data in a relational database.Advanced SQL: Discusses SQL commands and calculations that are more advanced.SQL Functions: Commonly-used math functions in SQL. For each command, the SQL syntax will first be presented and explained, followed by an example. Although it is a good idea to go through this tutorial in the above order, it is not required.
