确认数据字典

botang

数据字典视图都有两个特征：1. DBA/USER/ALL_跟上复数     2. 底表归SYS所有：

1.   select  text from dba_views where view_name like 'DBA%SNAP%';
   
2.   
   
3.   select text from dba_views where view_name ='INT$DBA_HIST_SNAPSHOT';
   
4.   
   
5.   select * from dba_tables where table_name='WRM$_SNAPSHOT';
