body: <p>How do you join the results of 2 queries, ordering by date?</p>
  
  <pre><code>SELECT * FROM table1 WHERE tag='1'
  SELECT * FROM table2 WHERE tag='3'
  </code></pre>
  
  <p>table1,table2 have the same fields:
  <code>id|article|author|tag|date</code></p>
  
  <p>PS: BY THE WAY, tag IS <code>workid</code></p>
