title: Get SELECT results ordered by "row id" in mySQL
body: <p>How can I get <code>SELECT</code> results ordered by <strong>row id</strong> if table does not have auto-increment column/key?</p>
  
  <p>Additionally, how can I for example get last 100 of them, using <code>LIMIT</code>, if I cannot use <code>ORDER BY</code> clause, as no auto-increment row is present?</p>
