JiekerTime opened a new issue #9608:
URL: https://github.com/apache/shardingsphere/issues/9608


   ### Which version of ShardingSphere did you use?
   5.0.0-RC1-SNAPSHOT
   
   ### Expected behavior
   
![image](https://user-images.githubusercontent.com/76552510/110307620-185ae280-803a-11eb-8982-9ebdf2fcb322.png)
   logical column name should different from actual column name
   
   ### Actual behavior
   
![image](https://user-images.githubusercontent.com/76552510/110307843-5952f700-803a-11eb-94b1-3c89d8bb72c1.png)
   They are same.
   
   ### Reason analyze (If you can)
   The metadata of column is logical name.
   This problem does not occur when  joint query, because it is obtained 
MetaData  from queryResultSample.

   In order to review the problem, you can try to set the breakpoint at 
following：
   DatabaseCommunicationEngine.createQueryHeader：
