I've managed to created an audit table in Oracle that audits records when they have been updated, deleted or inserted on the employees table. I have also made it so it only audits records when changes are made out of office hours (9am - 5pm).

IF you want to see the code for this please let me know, but i just wondered would it be possible to only audit records based on job role aswell. In the employee table there is a job role column such as this.

 Job_role
 Director
Security Guard II
Administration Manager
Warehouse Assistant I

I would only want it to audit changes made by for example a security guard or a warehouse assistant as these jobs roles should not really be interacting with the employee database.

Any help appreciated.

Thank you

What you need to do is store the user's job description in a session variable.

To do this you declare a namespace using the CREATE CONTEXT command. Docs here.

Then you have an AFTER-LOGON database trigger which queries the USERS table and stores the Job Description in the namespace using DBMS_SESSION.set_context(). Docs here.

Finally, when it comes to the auditing command you read the stored value with SYS_CONTEXT() and make the appropriate decision:

if sys_context('AUDIT_INFO', 'JOB_DESCR') = 'Warehouse Assistant I'   
then
    call_your_audit_proc(.....);
end if;
