SQL:1999 is the fourth revision of the SQL database query language. The latest revision of the standard is SQL:2008.



The SQL:1999 standard, also known as SQL3, was published in 1999. Unlike previous editions, the standard's name used a colon instead of a hyphen for consistency with the names of other ISO standards. SQL:1999 has several parts:[1]

Boolean data types

The SQL:1999 standard clearly state in ISO/IEC 9075-2:1999 section 4.6 Boolean types, but many commercial SQL Servers (Microsoft SQL Server 2005, Oracle 9i, IBM DB2) do not support it as a table type, variable type or allow it in the results set. MySQL interprets "BOOLEAN" as a synonym for TINYINT (8-bit signed integer).[2]
