Additions to the Foundation include
- enhanced MERGE and DIAGNOSTIC statements,
- the TRUNCATE TABLE statement,
- comma-separated WHEN clauses in a CASE expression,
- INSTEAD OF database triggers,
- partitioned JOIN tables,
- support for various XQuery regular expression/pattern-matching features, and
- enhancements to derived column names.[1]
Documentation
The SQL standards documentation is not freely available but may be purchased from the ISO as ISO/IEC 9075(1-4,9-11,13,14):2008.
Claims of conformance
The minimum level of conformance to SQL:2008 that a product can claim is called "Core SQL:2008" and is limited to definitions specified in two parts of the standard: the Foundation and the Information and Definition Schemas.[2]
