phalcon模型查询几种方法

$robots = Robots::query()
  ->where('type = :type:')
  ->andWhere('year < 2000')
  ->bind(['type' => 'mechanical'])
  ->limit(5, 10)
  ->orderBy('name')
  ->execute();

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();
