--第一步 在v$sqlarea 这视图里面找到你操作那条SQL的时间
select r.FIRST_LOAD_TIME,r.* from v$sqlarea r order by r.FIRST_LOAD_TIME desc ;

--第二步：把当前操作时间点的所有数据，导到一张新的恢复表中
create table customer_reject_log_recove 
as 
select * from customer_reject_log 
as of timestamp to_timestamp('2014-08-29 10:13:13','yyyy-mm-dd hh24:mi:ss');

--第三步，同步数据到原表中
--备份原表数据
insert into customer_reject_log_back select * from customer_reject_log;
--删除原表
delete from customer_reject_log;
--把恢复表的数据迁移到原表中
insert into customer_reject_log select * from customer_reject_log_recove;
