The components (clauses) for the SQL data-change statements (INSERT,
|
|
UPDATE, DELETE) are built upon the general query/statement components
|
|
defined in xml_query.xsd.

DataChangeStatementTablesType is the type for the <tables>
|
|
element in the data-change statements. This type only allows one named
|
|
table as content, which is subject to the INSERT, UPDATE or DELETE.
|
|
|
|
Most SQL implementations do allow multi-table UPDATE and DELETE
|
|
statements and the XML Query language can express multi-table UPDATEs.
|
|
|
|
Also adds the priority attribute to SqlStatementType, used by the
|
|
data-change statements.
