title: MySQL 5.7 error: Cannot get geometry object from data you send to the GEOMETRY field
body: <p>I have a column that is giving me a headache on MySQL Server 5.7.11.</p>
  
  <p>It was of type <code>POINT</code> and I was able to change it to type <code>GEOMETRY</code> with no issues.</p>
  
  <p>When I now try and change it from <code>GEOMETRY</code> to <code>POINT</code> I get the following error:</p>
  
  <p><code>Error 1416: Cannot get geometry object from data you send to the GEOMETRY field SQL Statement: ALTER TABLE</code>table<code>
  CHANGE COLUMN</code>column_name<code></code>column_name<code>POINT NOT NULL;</code></p>
  
  <p>I doesn't make sense to me why I could change it one way and not the other.</p>
  
  <p>I have been having trouble with the <code>POINT</code> datatype, especially when I try and do select statements, it sometimes comes with the same error.</p>
