title: Table-less UNION query in MS Access (Jet/ACE)
body: <p>This works as expected:</p>
  
  <pre><code>SELECT "Mike" AS FName
  </code></pre>
  
  <p>This fails with the error "Query input must contain at least one table or query":</p>
  
  <pre><code>SELECT "Mike" AS FName
  UNION ALL
  SELECT "John" AS FName
  </code></pre>
  
  <p>Is this just a quirk/limitation of the Jet/ACE database engine or am I missing something?</p>
