title: How can I get sets of 2 entries where each set starts with a different letter and no letter is repeated from a sqlite database?
body: <p>Like this:</p>
  
  <pre><code>apple
  aardvark
  banana
  bet
  cow
  car
  ...
  zipper
  zoo
  </code></pre>
  
  <p>Assuming the database has more than just two different entries that start with any of the letters. I was thinking of doing something with TOP and wildcards, but I don't really know enough about SQL to pull this off. What can I do?</p>
