However, nested transactions are not supported, even though parallel transactions on different tables are. The current release does not support stored procedures4 or native XML data type either. It uses a subset of T SQL3 for querying and due to lack of XML support, XQuery is not supported either. Queries are processed by an optimizing query processor.
