Return Value

Type: Usual
TRUE if successful; otherwise, FALSE.
Remarks
Sends a NotifyRecordChange message, if successful. This command discards all changes to the current row. It is useful as a way of implementing Undo in an application. However, it cannot roll back changes that have been committed with the SQLSelect:Commit(). Also, note that it applies only to the current row; the data server and the drivers do not buffer changes made to multiple rows.
