表名在数据库中的存储大写和小写略解

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

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;
<pre name="code" class="html">OWNER                          OBJECT_NAME
------------------------------ --------------------------------------------------------------------------------------------------------------------------------
LM                             DXMY   --大写

create table lm."dxmy"(id number);  --加引號之后。就存储想要的大写和小写


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
