Question
How to trap user ?
We would like to capture the user, whenever there is change to table in Update,delete.
In our organization all user are using single Oracle user. We used trigger on table using USERENV(TERMINAL) but this does not solve our problem because it only give the terminal name and it is not designated for sigle user. In actual we want to capture the user id which he uses to log on to application.
I thank in advance for all your valueable comments and suggestion.

if you create a user_name column or a user_id column and a modified_dt column on the table then you can collect history for free by setting the default values (when null is inserted) as follows:
user_name = USER
user_id = UID
modification_dt = SYSDATE
these should populate the columns for free each time a row is inserted.
when updating and/or deleting, you need a trigger to insert the data into a history archive table or manage the rows directly using the same reserved words.

Hi everybody,
Thanks for the prompt comments,
The comments provided to question all are correct but it cannot be applied here to trap a user who is updating or deleting record, since we are using single oracle user and common WIN 2000 logon for user.
Only thru the forms or Application Menu each user have unique id to logon, these are table values. this is the user id, which we want to capture thru the table trigger.
Thanks once again.
ok, so from the Forms/Application Menu you know the user ... then set it as a package variable there!
use the following package:
create or replace package xxx as
function getuser return varchar2;
procedure setUser(usr in varchar2);
end;
/
create or replace package body xxx as
varuser varchar2(30);
function getuser return varchar2 is
begin
return varuser;
end;
procedure setUser(usr in varchar2) is
begin
varuser := usr;
end;
end;
/
Then in your Forms/Menu Application where you logon use the SetUser procedure to set the user, and in your trgger use the GetUser function!
Cheers,
Stefan
