利用闪回查看Oracle表历史时刻数据

1.查看表历史时刻数据

select * from tab_test AS OF TIMESTAMP to_timestamp('20140917 10:00:00','yyyymmdd hh24:mi:ss');

2、利用flashback table恢复表到过去某一时刻

alter table tab_test enable row movement;

flashback table tab_test to timestamp ('20140917 10:00:00','yyyymmdd hh24:mi:ss');

alter table tab_test disable row movement;

3、查看过去某一段时间内对表的操作，，以确认需要恢复到的时间点

select SQL_TEXT,LAST_ACTIVE_TIME from v$sqlarea where LAST_ACTIVE_TIME >to_date('20140917 10:00:00','yyyymmdd hh24:mi:ss') and SQL_TEXT like '%tab_test%';

4、确认是否开启闪回

select log_mode,flashback_on from v$database;
