Auditing statements

Statement auditing along with session audits is another important tracing method for capturing suspicious operations performed by a user. Statement audits apply both for DML and DDL statements.

In this recipe we will implement statement audit and we will create a new table named HR_EMP_DETAILS_AUD from EMP_DETAILS_VIEW.

Getting ready

    SQL> conn HR
    Enter password:
    SQL> create table hr_emp_details_aud as select * from emp_details_view;
    Table created.
  2. Grant all privileges to SMAVRIS and DRAPHEAL on the HR_EMP_DETAILS_AUD table as follows:

    SQL> grant alter on hr.hr_emp_details_aud to smavris,drapheal;
    Grant succeeded.
    Audit succeeded.
