This article is about SQL:2003, a revision of the SQL standard. For more information about SQL, see the main SQL article.

SQL:2003 is the fifth revision of the SQL database query language. The latest revision of the standard is SQL:2008.

Summary

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:

• 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 TABLE statement, to allow "CREATE TABLE AS" and "CREATE TABLE LIKE"
• removal of the poorly-implemented "BIT" and "BIT VARYING" data types
