title: knex js, select is working but not delete
body: <p>Trying out the query builder knex.js, <a href="http://knexjs.org/" rel="nofollow">http://knexjs.org/</a></p>
  
  <pre><code>exports.deleteProduct = function(inputs, callback) {
    //Working
    knex( "products" ).select().exec(function(err, resp) { console.log(resp) });
  
    //Not working
    knex( "products" ).del().where( "pr_id", 349).exec(function(err, resp) {          console.log(resp) });;    
  }
  </code></pre>
  
  <p>The select statement works just fine. But not delete, also tried update. The response is 0. The record has not been deleted, have checked the db. I don't get any error if I run console.log(err) either.</p>
  
  <p>Any ideas?</p>
