The result of the SQL query has a method 'names()' that contains 
the column names.  N.B. This is a method of the result, not a 
method of the individual rows, so you cannot normally get at it 
directly while iterating over the result.

Try:

<dtml-let query="sqlListTable(table_name='personnel')"
       names="query.names()"> 
  <dtml-in query>
      <dtml-in names>
        <dtml-let column=sequence-item>
           <dtml-var column> is <dtml-var "_[column]"><br>
        </dtml-let>
      </dtml-in>
  </dtml-in>
</dtml-let>
