title: Query ORDER with UNION
body: <p>I have to do punt an &quot;*&quot; in a list of dates, like this:</p>
  <pre><code>*
  1/1/2021
  2/1/2021
  3/1/2021
  ...
  </code></pre>
  <p>So, with my low knowledge, I created something like this code:</p>
  <pre><code>SELECT Disciplines_Date.Date_Modification
  FROM Disciplines_Date
  ORDER BY Date_Modification DESC;
  UNION 
  SELECT UnionTable.ABC 
  FROM UnionTable;
  </code></pre>
  <p>where &quot;*&quot; is present in the table Union.
  But, the command ORDER doesn't work and I've a sort system just by number, like the follow:</p>
  <pre><code>*
  9/01/2021
  3/01/2021
  12/01/2021
  21/01/2021
  </code></pre>
  <p>How can avoid this? Thanks for the help</p>
