ORACLE 误删除视图恢复

1、使用 dba_views

回退到特定时间段，查看定义

 select view_name,text from (select * From dba_views  AS OF TIMESTAMP(SYSTIMESTAMP - INTERVAL '5' hour-INTERVAL '35'
 minute) ) where view_name='VP_TASKCLASS_INFO';

　　注意，这里必须要有DBA的权限

2、TEXT 是Long 类型，在SQLPLUS 里边要先设置下

SQL> set line 100;
SQL> set long 20000000;
SQL> set longchunksize 255;
SQL> spool c:\test.txt
SQL> select * from aaa
SQL>spool off
