Stored procedure for disabling all foreign key constraints ?

Question

hi all,
I need a stored procedure for disabling / enable all constraints in that database schema.
Create or replace procedure enable_disable_proc(status varchar2(3),schema_name varchar2(20))
---> where 'status' parameter condition should be ( YES for enable) (NO for disable)
---> 'schema_name' is a parameter where ,only this schema should be affected with this procedure..
Thanks in Advance..

Hi,
Try this code
/* Formatted on 2009/07/16 08:15 (Formatter Plus v4.8.8) */
CREATE PROCEDURE enab_disab_proc (
   enforce          IN   VARCHAR2,
   current_schema   IN   VARCHAR2
IS
   v_alter_table_sql   VARCHAR2 (2000);
BEGIN
   FOR rec_con IN (SELECT table_name, constraint_name
                     FROM user_constraints
                    WHERE owner = current_schema)
   LOOP
      IF (enforce = 'NO')
      THEN
         v_alter_table_sql :=
               ' alter table '
            || current_schema
            || '.'
            || rec_con.table_name
            || ' disable constraint '
            || rec_con.constraint_name;
      ELSE
         v_alter_table_sql :=
               ' alter table '
            || current_schema
            || '.'
            || rec_con.table_name
            || ' enable constraint '
            || rec_con.constraint_name;
      END IF;
      EXECUTE IMMEDIATE v_alter_table_sql;
   END LOOP;
END;Edited by: Salim Chelabi on 2009-07-16 05:15
