基于Flashback Query例子：
select  *  from gfmis_all.r_receipt_order_detail as of timestamp to_date('2012-04-12 20:00:00', 'yyyy-mm-dd hh24:mi:ss') a
minus
select * from gfmis_all.r_receipt_order_detail r;

select text from dba_source as of timestamp to_timestamp('2011-04-07 21:02:09','yyyy-mm-dd hh24:mi:ss') where name='GETDATE' order by line;

基于timestamp恢复的语句：
SELECT text
    FROM dba_source
         AS OF TIMESTAMP TO_TIMESTAMP ('XXXXX', 'YYYY-MM-DD HH24:MI:SS')
   WHERE owner = 'XXXX' AND name = '你删除的对象名'
ORDER BY line;
