oracle的监测TABLE数据更改情况
记录数据库登陆用户信息：
CREATE
oｒ
REPLACE
TRIGGER
LogonTrigger AFTER LOGON
ON
DATABASE
BEGIN
if
length(SYS_CONTEXT(
'
USERENV

inserｔ
INTO
AccountConnections (TERMINAL, UserName, SID, ISDBA, HOST, OS_USER, IP_ADDRESS, EventAction, EventDate)
VALUES

更改XX_TABLE表数据的用户信息：
CREATE
OR
REPLACE
TRIGGER

INSERT
OR
UPDATE
ON
XX_TABLE
FOR
EACH ROW
DECLARE
W_SYSTIMESTAMP
TIMESTAMP
