CREATE TABLE t
AS
   SELECT 1 id FROM DUAL;
CREATE OR REPLACE PROCEDURE my_procedure
AS
   v_id   t.id%TYPE;
BEGIN
   SELECT id INTO v_id FROM t;
END;
CREATE OR REPLACE PROCEDURE my_proc2
AS
BEGIN
   my_procedure;
END;
exec my_proc2;
DROP TABLE t;
ALTER PROCEDURE   dsamstrc.my_proc2
   COMPILE;
SELECT *
  FROM SYS.USER_ERRORS
WHERE NAME = 'MY_PROC2'
       OR NAME IN (SELECT REFERENCED_NAME
                     FROM dba_dependencies
                    WHERE NAME = 'MY_PROC2');

SELECT distinct *
  FROM SYS.USER_ERRORS
WHERE NAME in
       (SELECT name
        FROM dba_dependencies
connect by nocycle  name =  prior  referenced_name
start with NAME = 'MY_PROC2')
