title: Selecting rows where there are at least X rows with some values in a column via sqlite3?
body: <p>Say I have the following data:</p>
  
  <pre><code>|bookID|data|
  |1|a|
  |1|b|
  |1|c|
  |2|x|
  |2|y|
  |3|t|
  </code></pre>
  
  <p>I want to select all the books that have at least X rows.  So if X=3 then I'd only get all the rows with bookID=1.  If X=2 then I'd only get all the rows with bookID=1 or bookID=2, etc.</p>
  
  <p>Can I do this with SQLite3?</p>
