title: Cannot find ROW_NUMBER() function in mysql 8.0.17?
body: <p>I setup my web service by using package AppServ : Apache + PHP + MySQL, which is download from
  <a href="https://www.appserv.org/en/" rel="nofollow noreferrer">https://www.appserv.org/en/</a></p>
  <p>Mysql version is 8.0.17, and phpMyAdmin is 4.9.1</p>
  <p>When I tried to use ROW_NUMBER() function inside phpMyAdmin, it always told me some errors.
  Eventurally, I feel my Mysql might not include this function.</p>
  <p>Is it possible? and how to verify it (mysql hasn't row_number()) and how to solve it?</p>
