	because the SourceTable name is not present in BuildSchema

2003-02-24  Aleksey Demakov <avd@openlinksw.com>

	* DbDataAdapter.cs: The original code might pass a null DataTableMapping
	value which is then used to create a RowUpdatingEventArgs
	instance. So RowUpdatingEvent handler (for instance
	CommandBuilder) could get null DataTableMapping which
	might be unexpected. The patch makes sure that a non-null
	DataTableMapping is passed.

2003-01-26  Gonzalo Paniagua Javier <gonzalo@ximian.com>

	* DbEnumerator.cs: why does the runtime throw an invalid cast here? The
