This member will be removed in a future version of Microsoft SQL Server. Avoid using this member in new development work, and plan to modify applications that currently use this member. |
The run-time engine calls CanUpdate on new objects, passing in the GUID of the old object. If the new object can update the old object, the old object is passed to the new one through the Update method, where the XML is changed.
By default, all extensible objects implement CanUpdate to return false, and implement the Update method to do nothing on the XML it is given in its parameters.
