1，首先查找表的操作記錄

select * from v$sqlarea a where a.SQL_TEXT like '%TB_ACCT_SYSDATE%';

2，從上面的記錄中找到update語句對應的sql_id

select * from v$sqltext a,v$sqlarea b where a.SQL_ID=b.SQL_ID and b.SQL_ID in('cq53826tk4u3c','afftnrfhu5utk') order by b.LAST_ACTIVE_TIME desc;

3，從上面的記錄中找到最新的sql操作記錄，然后找到用戶名和主機

select * from sys.v_$session l,sys.v_$sql s where s.SQL_ID='cq53826tk4u3c' and l.USERNAME is not null;
