利用觸發器監控對某個表操作的使用者資訊

1、建立日誌表
create table SQL_MON
(
EXE_TIME DATE,
LOGON_TIME DATE,
SESSION_ID NUMBER,
IP_ADDRESS VARCHAR2(256),
MACHINE VARCHAR2(64),
OSUSER VARCHAR2(30),
PROGRAM VARCHAR2(64),
USERNAME VARCHAR2(30),
SQL_TEXT VARCHAR2(1000)
)

2、用sys使用者建立觸發器
CREATE OR REPLACE TRIGGER tri_test
AFTER update or delete ON kmuser.sd_item_com
FOR EACH ROW
BEGIN

insert into kmuser.sql_mon
select
sysdate exe_time
,s.logon_time
,userenv('sessionid') session_id
,sys_context('userenv','ip_address') ip_address
,s.machine
,s.osuser
,s.program
,s.username
,t.sql_text
from dual
left join v$session s on userenv('sessionid')=s.audsid
left join v$sqlarea t on s.sql_id=t.sql_id
;
END;
