title: Execute INSERT if table is empty?
body: <p>Is there a way to do an insert under a count condition, something like:</p>
  
  <pre><code>INSERT INTO my_table (colname) VALUES('foo') IF COUNT(my_table) &lt; 1
  </code></pre>
  
  <p>Basically I want to insert a single default record if the table is currently empty. I'm using mysql.</p>
