利用ORACLE闪回机制,将删除的表闪回回来
找到回收站里删掉的表
select * from user_recyclebin where DROPTIME >'2012-02-22 00:00:00';
在闪之前, 但删除的表,如果又重新创建了一样的表名,所以不能直接闪回,要先删除这些表, (如需删除冲突表,执行此以下查询结果内容中的sql语句)
select 'drop table '||ORIGINAL_NAME||' cascade constraint;' from user_recyclebin where DROPTIME >'2010-02-08 09:00:00' and type = 'TABLE';
( 生成闪回表的语句 )
select 'flashback table '||ORIGINAL_NAME||' to before drop;' from user_recyclebin where DROPTIME >'2012-02-22 17:00:00' and type = 'TABLE';
(索引恢复)
select 'ALTER INDEX "'||OBJECT_NAME||'" rename to '||ORIGINAL_NAME||';' from user_recyclebin where DROPTIME >'2012-02-22 17:00:00' and type = 'INDEX';
(触发器恢复)
select 'ALTER TRIGGER "'||OBJECT_NAME||'" rename to '||ORIGINAL_NAME||';' from user_recyclebin where DROPTIME >'2012-02-22 17:00:00' and type = 'TRIGGER';
