1、查询表创建时间
SELECT OBJECT_NAME, CREATED
FROM ALL_OBJECTS
WHERE OBJECT_TYPE = 'TABLE'
and object_name ='temp1'
ORDER BY CREATED DESC;
2、假如误操作
drop table temp1; commit;
3、查看回收站中表
select object_name,original_name,partition_name,type,ts_name,createtime,droptime from recyclebin;
object_name original_name
BIN$abcd$0 IND_TEMP1
BIN$hgcd$0 TEMP1
4、恢复表
flashback table test_drop to before drop;
flashback table "BIN$hgcd$0 " to before drop;
5、恢复索引
select INDEX_NAME from user_indexs where table_name='TEMP1'
INDEX_NAME
BIN$abcd$0
虽然看起来表已经恢复了,但是索引恢复的有点问题,恢复出来的索引名称不是IND_TEMP1,故我们还要手动完成索引名修改。
alter index "BIN$abcd$0" rename to IND_TEMP1;
6、清空回收站
purge recyclebin;
