Wie update cursor Datensätze mit WHERE CURRENT OF?

Ich bin immer "ORA-01410: Invalid ROWID" - Ausnahme beim ausführen in diesem block. Irgendwelche Ideen, warum?

DECLARE
  CURSOR c_orders IS
    SELECT * from orders FOR UPDATE OF no;
  v_order_record c_orders%ROWTYPE;
BEGIN
  OPEN c_orders; 
  LOOP
    FETCH c_orders INTO v_order_record;
    UPDATE orders SET no = 11 WHERE CURRENT OF c_orders;
    EXIT WHEN c_orders%NOTFOUND; 
  END LOOP;  
  CLOSE c_orders; 
END; 

Jedoch alles funktioniert, wenn die Verwendung FÜR die IN der syntax:

DECLARE
  CURSOR c_orders IS
    SELECT * from orders FOR UPDATE OF no;
BEGIN
  FOR rec IN c_orders
  LOOP
    UPDATE orders SET no = 11 WHERE CURRENT OF c_orders;
  END LOOP; 
END;
