oracle回滚误删并且commit的表

insert into qual_temp_detail select * from qual_temp_detail 
as of timestamp to_date(‘2014-12-29 08:30:22‘, ‘yyyy-mm-dd hh24:mi:ss‘) 

--闪回到15分钟前 
select *  from orders  as of timestamp (systimestamp - interval ‘‘15‘‘ minute)  where ...... 
这里可以使用DAY、SECOND、MONTH替换minute，例如： 
SELECT * FROM orders AS OF TIMESTAMP(SYSTIMESTAMP - INTERVAL ‘‘2‘‘ DAY) 

--闪回到两天前 
select * from orders  as of timestamp (sysdate - 2) where......... 

/*2.FLASHBACK DROP*/ 

  1.flashback table orders to before drop; 
  
  2.如果源表已经重建，可以使用rename to子句： 
  flashback table order to before drop  rename to order_old_version; 
  
/*3.FLASHBACK TABLE*/ 

  1.首先要启用行迁移： 
  alter table order enable row movement; 
  2.闪回表到15分钟前： 
  flashback table order  to timestamp systimestamp - interval ‘‘15‘‘ minute; 
    闪回到某个时间点： 
  FLASHBACK TABLE order TO TIMESTAMP    TO_TIMESTAMP(‘2007-09-12 01:15:25 PM‘,‘YYYY-MM-DD HH:MI:SS AM‘)
