- find方法：
- findFirst方法，将返回
Phalcon\Mvc\Model\Criteria对象 - Criteria方法 模型的
query()将返回Phalcon\Mvc\Model\Criteria对象
$robots = Robots::query()
->where('type = :type:')
->andWhere('year < 2000')
->bind(['type' => 'mechanical'])
->limit(5, 10)
->orderBy('name')
->execute();

Buider 是PHQL中的子功能
use Phalcon\Mvc\Model\Manager as ModelsManager;
$builder = $this->modelsManager->createBuilder()
->columns('id, name')
->from('Robots')
->orderBy('name');
// Getting a whole set
$robots = $this->modelsManager->createBuilder()
->from("Robots")
->join("RobotsParts")
->orderBy("Robots.name")
->getQuery()
->execute();
// Getting the first row
$robots = $this->modelsManager->createBuilder()
->from("Robots")
->join("RobotsParts")
->orderBy("Robots.name")
->getQuery()
->getSingleResult();
