hi friends, In getting auditing info from sys.aud$,
user_audit_trail etc.. views I am able to view session,
statement no, action number etc.. columns only
how can i view the statment also.
for e.g
sql>audit alter on emp;
sql>alter table emp modify ename varchar2(30);

in audit info. i want to see the above statement also.

rememeber this is not in sys user.

use dbms_fga

something like
AUDIT ALTER TABLE ON user.tabname
by access
whenever successful;
