title: phpmyadmin won't change MySQL TINYINT(1) to BOOLEAN data type
body: <p>I'm running MySQL 5.5.47 and have a number of database tables that have columns with a data type of <code>TINYINT(1)</code>. I'm attempting to change these to <code>BOOLEAN</code> but it won't change them.</p>
  
  <p>Using phpmyadmin 4.6.0 then going to Structure I'm using the dropdown to set the columns to <code>BOOLEAN</code>. This executes the following query:</p>
  
  <pre><code>ALTER TABLE `feedback` CHANGE `tick_receive_updates` `tick_receive_updates` BOOLEAN NOT NULL;
  </code></pre>
  
  <p>The query runs successfully.</p>
  
  <p>When I view the Structure it does not update: the columns are still marked as being <code>TINYINT(1)</code></p>
  
  <p>At first I thought this was a phpmyadmin bug so I ran</p>
  
  <pre><code>DESCRIBE feedback;
  </code></pre>
  
  <p>Unfortunately the problem remains - columns have not changed from <code>TINYINT(1)</code></p>
  
  <p>Why is this?</p>
