今天同事表示对于自己创建的表名是小写,在expdp的parfile中,include=view:"('view_name')",这个view_name用小写为什么提示:

ORA-39168: Object path VIEW was not found.
ORA-31655: no data or metadata objects selected for job

我表示建立视图的时候是小写,但是它存在数据字典中的时候,自动会变成大写。这是Oracle的存储方式。
create table lm.dxmy(id number);   --小写

select d.owner,d.object_name from dba_objects d where owner='LM' order by d.object_name;
OWNER OBJECT_NAME ------------------------------ -------------------------------------------------------------------------------------------------------------------------------- LM DXMY --大写


如果:
create table lm."dxmy"(id number);  --加引号之后,就存储想要的大小写


SQL> select d.owner,d.object_name from dba_objects d where owner='LM' order by d.object_name desc; 

OWNER                          OBJECT_NAME
------------------------------ --------------------------------------------------------------------------------------------------------------------------------
LM                             dxmy   --定义的小写
