# Oracle Flashback Technology ###### tags: `Database` `Oracle` `SQL` 不小心把資料庫異動錯,幸好有使用此feature將資料就回來, 所以將此feature介紹如下: http://docs.oracle.com/cd/B28359_01/appdev.111/b28424/adfns_flashback.htm#BJFDJCJD 這次用到其中 ## Flashback Query 以下有講如何config,如何使用 http://oracle-base.com/articles/9i/flashback-query.php 需要有 ## Automatic Undo Management 才能使用Flashback Query 以下講如何 config Automatic Undo Management http://oracle-base.com/articles/9i/automatic-undo-management.php 其中使用SQL: ```SQL SELECT oea01,oeaud02 FROM oea_file AS OF TIMESTAMP TO_TIMESTAMP('2015-05-07 12:00:00', 'YYYY-MM-DD HH:MI:SS') where oea01 like 'ASO7-1504%'; ``` 呼叫出當時未異動前的資料
