title: How to add value to a subquery?
body: <p>I have this simple query:</p>
  
  <pre><code>SELECT DISTINCT images.id
  FROM `images`
  WHERE `images`.`user_id` IN
      (SELECT following_id
       FROM `follows`
       WHERE `follows`.`follower_id` = 5717
         AND `follows`.`accepted` = 1)
  ORDER BY id DESC LIMIT 1000
  OFFSET 0
  </code></pre>
  
  <p>I want to append a value to the list of values returned by the subquery. So if the subquery returns:</p>
  
  <pre><code>23
  59
  14
  77
  </code></pre>
  
  <p>I want it to be:</p>
  
  <pre><code>23
  59
  14
  77
  86
  </code></pre>
  
  <p>(note the extra 86 at the bottom).</p>
