list of all the names and display names of all fields in an entity.

Hi Experts, 

I'm Trying to get the list of all the names and display names of all fields in an entity. 

but the following query gives me more duplicate data. 

Select  * from  [MetadataSchema].[Attribute] a  inner join [MetadataSchema].[Entity] e on  e.EntityId=a.EntityId where e.Name='entity name'

on  e.EntityId=a.EntityId
