What's wrong with using the delete button on the tool bar?

From a table, or from a form? Did you re-query?

Why are you doing a manual delete?

If your block is based on 'mcl_sar_login' then use 'delete_record'.

When doing a manual operation in Oracle Forms use the manual commit called 'standard.commit'.

Sir,
Yes my block is mcl_sar_login. But by delete_record the record is not deleted from database. My code is :
begin
--v_user := :user_name;
delete from mcl_sar_login where user_name = :mcl_sar_login.user_name;
delete_record;
standard.commit;
clear_form;
go_item('user_name');

end;

Basically, what you do is wrong.

Remove that button (doing so, trigger will also be deleted) and use Forms' toolbar which contains a "delete record" button.

If you insist on your own code, then
