Remarks

You should first read and understand the documentation for IRowsetChange, because everything described there also applies here. You should also read chapter 6 of the OLEDBProgrammer'sReference on setting data.

IRowsetUpdateImpl implements the OLE DB IRowsetUpdate interface, which enables consumers to delay the transmission of changes made with IRowsetChange to the data source and undo changes before transmission.
