title: vb.net "the schema returned by query is differ from base query" in winforms
body: <p>I am working on vb.net windows application. When I Tried to add query by "Query Builder" after selecting data adapter and data set from datagrid view I receive this error:</p>
  
  <pre><code>the schema returned by query is differ from base query
  </code></pre>
  
  <p>MY QUERY IS LIKE THIS:</p>
  
  <pre><code>SELECT        
      CompanyMaster_tbl.CompanyName, 
      DepartmentMaster_tbl.dtName, 
      DepartmentMaster_tbl.dtPhone, 
      DepartmentMaster_tbl.dtEmail
  FROM            
      CompanyMaster_tbl 
      INNER JOIN DepartmentMaster_tbl ON CompanyMaster_tbl.Cid = DepartmentMaster_tbl.cId
  </code></pre>
  
  <p>First I added the company name to datagrid view choosing the data source and particular table name but while clicking Ok button am getting the error.</p>
