title: DataTable.Compute not working
body: <p>Am using <code>DataTable.Compute()</code> method , but getting </p>
  
  <blockquote>
    <p>" Syntax error in aggregate argument: Expecting a single column
    argument with possible 'Child' qualifier. "</p>
  </blockquote>
  
  <p>My Code : </p>
  
  <pre><code>  int x = Convert.ToInt32(DataSet1.Tables[0].
         Compute("SUM(Convert([qty],'System.Int32'))","[code] = 'ABC'"));
  </code></pre>
  
  <p>Here code is column of datatable and am reading the sum of qty. But I think the error might be because of qty is of type <code>string</code> and not able to convert into int type, but not sure.</p>
  
  <p>Looking forward for answer and thanks in advance.</p>
