title: SELECT doesn't display column names
body: <p>When I don't use the SET command, I get results like:</p>
  
  <pre><code>SQL&gt; select * from &lt;tablename&gt;;
  
           NAME          PLACE        AGE         GENDER        DESTINATION
      -------------- -------------- ---------   ------------  ---------------
            Joy         Scotland      22           Male          California
  </code></pre>
  
  <p>When I use the SET variable :</p>
  
  <pre><code>SET LIN 32000 pagesize 0
  
  SQL&gt; select * from &lt;tablename&gt;;
  </code></pre>
  
  <p>I get the results in better format but not too good:</p>
  
  <pre><code> Joy Scotland                                     22 Male                                                                             California
  </code></pre>
  
  <ol>
  <li>How can I display the output in better way (e.g. columns are separated with a delimiter (space))</li>
  <li>When we use SET, why did the column headers disappear? How can I improve it?</li>
  </ol>
