title: Deprecation Warning Python mysql connector
body: <p>I am using the python mysql connector with sqlalchemy.
  I try to use this code to truncate a table:</p>
  <pre><code> session = db.Session()
  
   session.execute('''TRUNCATE TABLE Orders''')
   session.commit()
  </code></pre>
  <p>But I receive this warning.</p>
  <p>python3.8/site-packages/mysql/connector/connection_cext.py:506: DeprecationWarning: PY_SSIZE_T_CLEAN will be required for '#' formats

  <p>I receive this issue also for other queries. The provided example is just for being an example.</p>
