Structured Query Language

Structured Query Language (SQL) is a widely-used programming language for working with relational databases. The name of the language is generally pronounced as the three letters of its abbreviation About this sound '?s kju: '?l or, in some people's usage, as About this sound 'si:kw?l.

This Study Guide provides a short description of SQL, its origins, basic concepts and components, and a lot of examples. the guide follows the specifications of the SQL:2011 standard, which is developed by a common committee of ISO and IEC. Their publications are not freely available, but can be ordered online.[1] Or you may want to refer to a working draft, which you can download from Whitemarsh Information Systems Corporation.
