title: With join what must be the fields in order to take all the values?
body: <pre><code> $query = db_select('watchdog', 'wa');
   $query-&gt;leftJoin('malgona', 'm', 'm.wid = wa.wid')
         -&gt;fields('m');
  </code></pre>
  
  <p>If I put in fields <code>m</code> I only take the values of <code>m</code> and if I put <code>wa</code> I only take the values of <code>wa</code>. What must be the fields value in order to take the join (with values from both tables)?</p>
