Cursor..::.MovePrevUnique Method (LockingInfo)
Cursor Class See Also Send Feedback

If the cursor is not yet initialized, MovePrevUnique is identical to MoveLast(LockingInfo). Otherwise, move the cursor to the previous non-duplicate key in the database, and store that key and associated datum in Current. MovePrevUnique returns false if no non-duplicate key/data pairs exist after the cursor position in the database.
