title: Get entries in order they were inserted without a primary key?
body: <p>I am wondering if it is possible to query any database entries in order they were inserted without a primary key?</p>
  
  <p>Is there a specification in the SQL which order the entries have on a query like this:</p>
  
  <pre><code>SELECT *
  FROM tbl
  LIMIT 5
  </code></pre>
