title: Compare values in two columns
body: <p>I need help in returning values in a query.  Consider my example below where the values in Column A are linked to Column B:</p>
  
  <pre><code>Column A             Column B
  ---------            ---------
  45008                AQZ45008D
  45008                ABC12345
  45007                45007AX
  45007                11652019
  45007                JMD45007
  </code></pre>
  
  <p>All I need is to return rows where values in Column A are found somewhere in Column B.  So in this example, rows 1, 3, and 5 would need to be returned.</p>
  
  <p>I hope this was a clear example.  Thanks for your help!</p>
