title: Knex.js multiple orderBy() columns
body: <p>Is it possible to do multiple orderBy() columns?</p>
  
  <pre><code>knex
    .select()
    .table('products')
    .orderBy('id', 'asc')
  </code></pre>
  
  <p>The orderBy() chainable only takes a single column key and a sort value, but how can I order by multiple columns?</p>
