Answer 1

hi
thanks Abdetu and Andreas Weiden. thanks to both of u for ur kind help. the following code did my job but by now another problem has risen.
my project calls different forms from the main_form. when i change the password via the following code, the password is not refreshed into the session information, due to which i can not move between different modules. the form simply collapses.
can u people please suggest something to fix it up....?
hoping for help,
regards...
Forms_DDL ('ALTER USER '||:MAIN_ITEMS.CURR_USER||' IDENTIFIED BY ' || :CHANGE_PASS.NEW_PASS);
               IF Form_Success THEN
                    a := SHOW_ALERT ('SUCCESS');
                    :CHANGE_PASS.OLD_PASS := NULL;
                    :CHANGE_PASS.NEW_PASS := NULL;
               :CHANGE_PASS.CONFIRM_NEW_PASS := NULL;
               END IF;
