title: cursor.fetchone() returns None even though a value exists
body: <p>I am trying to figure out how to fetch a single value from a UserID and print it in the console. My current piece of code keeps returning "None" even though there is a value for Currency for the UserID I am searching.</p>
  
  <pre><code>cursor.execute("SELECT Currency FROM ServerUsers WHERE USERID = %s" % (userid))
      if cursor.fetchone():
          a = cursor.fetchone()
          print(a)
  </code></pre>
