title: What's the difference between knex.raw() and knex.schema.raw()?
body: <p><code>knex.raw(sql, bindings)</code> and <code>knex.schema.raw(statement)</code>.</p>
  
  <p>It seems that these two functions have different signature.</p>
  
  <p>If they are equivalent, how can I use <code>knex.schema.raw(statement)</code> and pass <code>bindings</code> to it?</p>
