title: Laravel db migration - renameColumn error - Unknown database type enum requested
body: <p>I am using Laravel <code>4.2</code>. I have the following library loaded in my <code>composer.json</code></p>
  
  <pre><code>"doctrine/dbal": "2.4.*",
  </code></pre>
  
  <p>I created the following migration:</p>
  
  <pre><code>class RenameDeliveryNotesColumnOnOrderHeaderTable extends Migration {
  
      public function up()
      {
          Schema::table('order_header', function(Blueprint $table)
          {
              $table-&gt;renameColumn('delivery_notes', 'packing_notes');
          });
      }
  
  }
  </code></pre>
  
  <p>Where <code>delivery_notes</code> column type is <code>text</code>.</p>
  
  <p>When I run the migration, I get the following error:</p>
  
  <blockquote>
    <p>[Doctrine\DBAL\DBALException]   Unknown database type enum requested,
    Doctrine\DBAL\Platforms\MySqlPlatform may not support it.</p>
  </blockquote>
  
  <p>Any idea why I am getting this error? How should I go about fixing this? I need to rename a column in my table. Are there any alternative way to rename the column?</p>
