SQL:2003
SQL:2003 is the fifth revision of the SQL database query language. The standard consists of 9 parts which are described in detail in SQL. It was updated by SQL:2006.
New features
The SQL:2003 standard makes minor modifications to all parts of SQL:1999 (also known as SQL3), and officially introduces a few new features such as:[1]
- XML-related features (SQL/XML)
- Window functions
- the sequence generator, which allows standardized sequences
- two new column types: auto-generated values and identity-columns
- the new MERGE statement
- extensions to the CREATE TABLEstatement, to allow "CREATE TABLE AS" and "CREATE TABLE LIKE"
- removal of the poorly implemented "BIT" and "BIT VARYING" data types
Documentation availability
The SQL standard is not freely available but may be purchased from ISO or ANSI. A late draft is available as a zip archive from Whitemarsh Information Systems Corporation. The zip archive contains a number of
PDF
files that define the parts of the SQL:2003 specification.
