[Solved] Is Oracle MERGE NOT MATCHED THEN UPDATE possible?

Matthew Walk Asks: Is Oracle MERGE NOT MATCHED THEN UPDATE possible?
We’d like to set the IS_DEL bit = 1 when a record exists in a Target table that doesn’t exist in the Source table.

Is it possible to use a MERGE statement using the WHEN NOT MATCHED clause, but make it perform an UPDATE?

When attempting to do so, I’m getting a “ORA-00905: missing keyword” message.

Code:
MERGE
INTO    AMEPSA.ENTERPRISE_LOCATION trg
USING   (
        SELECT C.LOCATION_KEY as LOCATION_KEY
        FROM AMEPSA.ENTERPRISE_LOCATION C
            INNER JOIN AMESTAGE.VW_LOCATION L ON C.REC_SRC_KEY_CD = L.LOCATION_ID    
        WHERE C.CURR_REC_IND = 'Y'
        ) src
ON      (trg.LOCATION_KEY = src.LOCATION_KEY)
WHEN NOT MATCHED THEN UPDATE
    SET trg.IS_DEL = 1

Does the “WHEN NOT MATCH” clause only support “THEN INSERT”?
