audit_column_opts => DBMS_FGA.ANY_COLUMNS);
end;

----启用策略
begin
DBMS_FGA.ENABLE_POLICY (

object_name => 'EMP',
policy_name => 'mypolicy1',
enable => TRUE);
end;

select * from dba_fga_audit_trail;
select * from dba_audit_policies;

select db_user,timestamp,sql_text,sql_bind from dba_fga_audit_trail; --审计结果

SELECT text FROM dba_Views where view_name=upper('DBA_FGA_AUDIT_TRAIL'); --查看记录
