Hi Sridharan if you accept a suggestion, as I understand it is so

1. put the return at the end, not conditional, is better to have only one return
2. I think you forgot the loop

CREATE OR REPLACE FUNCTION Recursive_function (p_parent IN NUMBER)

   RETURN NUMBER
IS

   v_parent NUMBER (5);
   v_val NUMBER(5);
BEGIN while true loop

   SELECT PARENT_ID=20

     INTO v_parent
     FROM DSCR_CONTENT

    WHERE DSCR_CONTENT_ID = p_parent;

   IF v_parent IS NULL THEN

      exit;
   ELSE
      p_parent :=3D Recursive_function (p_parent);    END IF;
end loop;

 RETURN (p_parent);
END Recursive_function;
