title: Mule - Record cannot be mapped as it contains multiple columns with the same label
body: <p>I need to do join query to MS SQL Server 2014 DB based on a column name value. The same query runs when doing query directly to DB, but when doing query through Mule I'm getting error. The query looks something like this :</p>
  
  <pre><code>  SELECT *  FROM sch.emple JOIN  sch.dept on sch.emple.empid = sch.dept.empid;
  </code></pre>
  
  <p>The above query work fine while doing query directly to MS SQL Server DB, but gives the following error through mulesoft.</p>
