以scott用戶的emp表為示例
    ----增加策略
    begin
    dbms_fga.add_policy (
    object_schema => 'scott',
    object_name => 'emp',
    policy_name => 'mypolicy1',
    handler_schema => null,
    handler_module => null,
    enable => true,
    statement_types => 'insert, update,delete',
    audit_column_opts => dbms_fga.any_columns);
    end;
    ----啟用策略
    begin
    dbms_fga.enable_policy (
    object_schema => 'scott',
    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; --審計(jì)結(jié)果
    select text from dba_views where view_name=upper('dba_fga_audit_trail'); --查看記錄
    ----刪除策略
    begin
    dbms_fga.drop_policy (
    object_schema=>'scott',
    object_name=>'emp',
    policy_name=>'mypolicy1'
    );
    end;
