I have an SQL MERGE statement working perfectly in Oracle 11g (development environment), but it gives me the following error when I try to run it in Oracle 9i (Production environment): ORA-00905: missing keyword.

Is there any way to make this work in Oracle 9i? Here is statement:

MERGE INTO non_asset dst
   USING (SELECT tag, comments, computer_role
            FROM non_asset_backup
           WHERE sub_group = 'AALVOIP') src
   ON (dst.tag = src.tag)
   WHEN MATCHED THEN
      UPDATE
         SET dst.comments = src.comments,
             dst.computer_role = src.computer_role

    In 9i both the WHEN MATCHED and the WHEN NOT MATCHED branches were mandatory. In 10g and after one of them can be missing (but not both, obviously).
