title: Select all rows that have column value larger than some value
body: <p>I have a SQL table thus:</p>
  
  <pre><code>username  |  rank 
  a         |  0
  b         |  2
  c         |  5
  d         |  4
  e         |  5
  f         |  7
  g         |  1
  h         |  12
  </code></pre>
  
  <p>I want to use a single select statement that returns all rows that have rank greater than the value of user e's rank.</p>
  
  <p>Is this possible with a single statement?</p>
