title: Why can't I use the alias? using raw LARAVEL
body: <p>The problem is, that the alias <code>fechas</code> doesn't take any value... I can't use it</p>
  
  <pre><code>&gt;    $tabla_c2 = DB::table('horarios')
  &gt;     -&gt;select('id_voluntario',DB::raw("DATE_FORMAT(fecha,'%y-%m-%d')as fechas"))
  &gt;     -&gt;where('id_voluntario','=', $temp)
  &gt;     -&gt;where('fechas','=', $datee)
  &gt;     -&gt;get();
  </code></pre>
