SQL-92, SQL-99 and SQL-2003
BNF Grammars in various formats
Last updated: Fri, 4-Jun-2012

SQL-92

Here is a heavily hyperlinked HTML version of the BNF grammar for SQL-92 (ISO/IEC 9075:1992 - Database Language - SQL). The plain text file from which it was automatically converted is more useful (read legible) for reading without a browser.

SQL-99

Here is a heavily hyperlinked HTML version of the BNF grammar for SQL-99 (ISO/IEC 9075-2:1999 - Database Languages - SQL - Part 2: Foundation (SQL/Foundation)). The plain text file from which it was automatically converted is more useful (read legible) for reading without a browser.

SQL-2003

Here is a heavily hyperlinked HTML version of the BNF grammar for SQL-2003 (ISO/IEC 9075-2:2003 - Database Languages - SQL - Part 2: Foundation (SQL/Foundation)). The plain text file from which it was automatically converted is more useful (read legible) for reading without a browser.

There is a separate file HTML for the information from ISO/IEC 9075-1:2003 - Database Languages - SQL - Part 1: Framework (SQL/Framework). It was automatically converted from the plain text file, which is more useful (read legible) for reading without a browser.

Also available:

  • SQL 2003 Core Features
  • SQL 2003 Non-Core Features

    • Informix OUTER Join Syntax

    Here is an HTML explanation of the Informix OUTER join syntax.

    Conversion tools

    The plain text was converted to HTML by a Perl script which you may use if you wish. Or, output to YACC with this Perl script. The program also uses WEBCODE version 1.07 which you can download as a gzipped tar file. Note: The previous version of this file was called webcode-1.3.tgz, which actually meant V 1.03. Lastly, there is a makefile here.

    Download

    You can download a gzipped tar file containing the raw grammars, the HTML versions of those grammars, and the conversion tools as the gzipped tar file sql-bnf.tgz .
