$session->sql("DROP DATABASE IF EXISTS addressbook")->execute();
$session->sql("CREATE DATABASE addressbook")->execute();
$schema = $session->getSchema("addressbook");
$create = $schema->createCollection("people");
$create
->add('{"name": "Alfred", "age": 18, "job": "Butler"}')
->execute();
$create
->add('{"name": "Reginald", "age": 42, "job": "Butler"}')
->execute();
// ...
$collection = $schema->getCollection("people");
$result = $collection
->find()
->sort('job desc', 'age asc')
->execute();
var_dump($result->fetchAll());
