If you usesomthing like the follwoing you're OK:



DECLARE

  v_rowid ROWID;

BEGIN

  SELECT rowid

  INTO   v_rowid

  FROM   emp

  WHERE  empno = 1234

  FOR UPDATE;



  -- Do something



  UPDATE emp

  SET    sal = 2000

  WHERE  rowid = v_rowid;

  COMMIT;

END;

/




If you actually store the rowids in a table, or generate them manually your screwed. You can use the DBMS_ROWID package to convert them but I wouldn't bother.



You should really consider re-engineering your system to avaios the use of stored rowids if possible. As well as this upgrade issue you are prevented from using export/import.
