Exception handling in calling procedure

Question

Hi,
i have a package where currently am making calls to private procedures from public procedure.
and the senario is:-
create package body p_tst
is
ex_failed exception;
-- this is private proc
procedure p_private
is
begin
raise ex_failed;
exception
when ex_failed
then
raise;
end p_private;
procedure p_public
is
begin
-- nomaking call to private
-- procedure
p_private;
-- here i need to catch
-- the raised exception
-- passed from the called
-- procedure
when ex_failed
end p_public;
end;
basically i want to catch the exception being passed from called procedure to calling procedure, and raise the same exception in calling procdure.
is it possible to catch the same exception in the calling procedure?

Answer 1

Yes, you can catch the same exception in the calling procedure, exceptions are propagated to the caller if they are not handled in the called procedure.
Is this what you are trying to do?
CREATE OR REPLACE PACKAGE p_tst
AS
   PROCEDURE p_public;
   ex_failed   EXCEPTION;
END;
CREATE OR REPLACE PACKAGE BODY p_tst
IS
   PROCEDURE p_private
   IS
   BEGIN
      RAISE ex_failed;
   END p_private;
   PROCEDURE p_public
   IS
   BEGIN
      p_private;
   EXCEPTION
      WHEN ex_failed
      THEN
         DBMS_OUTPUT.put_line ('error');
   END p_public;
END;
SQL> set serveroutput on;
SQL> exec p_tst.p_public;
error
