title: How can I find the values in a table that occur more than once?
body: <p>I have a table with some fields that have the same value in more than one record. I want to get these values that occur more than once.</p>
  
  <p>So far I tried to use the following code to write the field values to the infolog. But this implementation writes all values, not just the ones that occur more than once:</p>
  
  <pre><code>while select myTable
  {
      info(strFmt("%1" ,  myTable.getFieldValue("myFieldName") )) ;
  }
  </code></pre>
  
  <p>How could I change this implementation to only get the values that occur more than once?</p>
