Keeping track of anyone who made a deletion from a table

Question

Dear all;
I thought this was going to be easy but I am yet to think of a solution to this problem. I have the following table created
create table test_tbl
   test_id varchar2(10) not null,
   test_modifiedby varchar2(30),
   test_result number(10),
   primary key(test_id)
);with the following insert
insert into test_tbl
  (test_id, test_modifiedby, test_result)
values
  ('122', 'John', 4);
insert into test_tbl
  (test_id, test_modifiedby, test_result)
values
  ('123', 'Jamie', 6);
insert into test_tbl
  (test_id, test_modifiedby, test_result)
values
  ('124', 'Katy', 8);
insert into test_tbl
  (test_id, test_modifiedby, test_result)
values
  ('125', 'Eric', 10);I am trying to write a simple procedure which is used for deletion and also I would like to be able to keep track on and the save the user who made the deletion and that is where I am having problems. I need to keep track on who made the deletion because I have a trigger which is used to save all deleted test_id made. See trigger below
CREATE OR REPLACE TRIGGER test_tbl_before_delete
BEFORE DELETE ON test_tbl
for each row
begin
insert into audit_test_tbl_table
    (test_id, test_modifiedby, test_result)
values
   (:old.test_id,
    :old.test_modifiedby,
    :old.test_result
end;Please how do I solve this problem. All help will be appreciated. Thank you.

Unfortunately Rob, I wouldnt be able to do that because I am using a web development tool called Asp.net which is linked to our oracle database and from the web development tool, users are able to login into the application I am designing and based on their login creditials, they are able to carryout tasks like deletions, insertions, etc. Now I am able to get the user name and info directly from the web development and able to pass it into my deletion procedure. See procedure below
procedure deletefromtest_tbl(delete_testid in varchar2, delete_modifieruser in varchar2)
  AS
temp_cnt number;
BEGIN
select count(*) into temp_cnt from test_tbl td
where td.test_id = delete_testid
if(temp_cnt != 0) then
    delete test_tbl pk
    where pk.test_id = delete_testid
  commit;
    end if;
end deletefromtest_tbl;From the procedure, I really don't know how to apply the delete_modifieruser (which contains the information of the user that perform the delete) so that information gets saved in the audit_test_tbl_table.
