Question

Hi
To audit what rows inserted , deleted and updated in a particular table i am using the below code . However is there a way i can just get the count of rows inserted , updated and deleted based on date or user . Also please tell me how can i get the terminal and machine name of the USER.
PACKAGE:
CREATE OR REPLACE package audit_pkg
as
procedure check_val( l_tname in varchar2,
l_cname in varchar2,
l_new in varchar2,
l_old in varchar2 , action in varchar2);
procedure check_val( l_tname in varchar2,
l_cname in varchar2,
l_new in date,
l_old in date , action in varchar2);
procedure check_val( l_tname in varchar2,
l_cname in varchar2,
l_new in number,
l_old in number , action in varchar2 );
end;
PACKAGE BODY
CREATE OR REPLACE package audit_pkg
as
procedure check_val( l_tname in varchar2,
l_cname in varchar2,
l_new in varchar2,
l_old in varchar2 , action in varchar2);
procedure check_val( l_tname in varchar2,
l_cname in varchar2,
l_new in date,
l_old in date , action in varchar2);
procedure check_val( l_tname in varchar2,
l_cname in varchar2,
l_new in number,
l_old in number , action in varchar2 );
end;

Hi
I'm not sure but i don't see that you are "auditing" time of the change and user to. You should expand your audit table ( and package )
with time and user atribut .
User , terminal , machine and much other things you can retrieve with sys_context function. For time you can use systimestamp function for example ..
http://www.psoug.org/reference/sys_context.html ( quite good reference )
For auditing things like machine you should be careful , if you are accesing your app through some http server you wil get the machine on which the server runs
and not the "client machine" from which the client has access the application throug that server .
