Question

我在Doctrine2中找不到任何有关命名查询的文档。请帮忙。 Doctrine2是否具有命名查询功能？

Answer 1

您可以使用

NamedQuery - DQL。实施例

use Doctrine\ORM\Mapping\NamedQuery;
use Doctrine\ORM\Mapping\NamedQueries;

/**
* @Entity
* @Table(name="cms_users")
* @NamedQueries({
*     @NamedQuery(name="activated", query="SELECT u FROM __CLASS__ u WHERE u.status = 1")
* })
*/
class CmsUser
{}

并称之为

$this->getDoctrine()->getRepository('MyBundle:CmsUser')
    ->createNamedQuery('activated')
    ->getResult();

NamedNativeQuery - SQL。更多信息请访问：http://docs.doctrine-project.org/en/latest/reference/native-sql.html#named-native-query

在EntityRepository中收集查询，例如：

namespace Acme\StoreBundle\Repository;

use Doctrine\ORM\EntityRepository;

class ProductRepository extends EntityRepository
{
    public function findAllOrderedByName()
    {
        return $this->getEntityManager()
            ->createQuery('SELECT p FROM AcmeStoreBundle:Product p ORDER BY p.name ASC')
            ->getResult();
    }
}

Answer 2

也许您会对EntityRepositories感兴趣，您可以在其中创建和存储复杂的Doctrine查询，并在项目中调用您想要的主题：

http://symfony.com/doc/current/book/doctrine.html#custom-repository-classes

Answer 3

如果您不想搞乱实体定义，可以在存储库的构造函数中调用注释表示法内部使用的函数：

namespace MyBundle\Repository;

use Doctrine\ORM\EntityRepository;

class CmsUserRepository extends EntityRepository
{
    public function __construct($em, \Doctrine\ORM\Mapping\ClassMetadata $class)
    {
        $this->getClassMetadata()->addNamedQuery(array(
            'name'  => 'activated',
            'query' => 'SELECT u FROM __CLASS__ u WHERE u.status = 1'
        ));
    }
}

您还可以使用实体的命名空间和类替换语句的__CLASS__部分，例如MyBundle\Entity\CmsUser

我发现这个问题正在寻找Native Named Query示例，上面的答案帮助了我，所以我想我会以同样的方式分享如何进行原生命名查询。

将其添加到实体存储库的构造函数

public function __construct($em, \Doctrine\ORM\Mapping\ClassMetadata $class)
{
    parent::__construct($em, $class);
    $this->getClassMetadata()->addNamedNativeQuery(
        array('name' => 'published', 
              'query' => 'SELECT 
                  t0.id AS id, 
                  t0.tracking_uri AS tracking_uri, 
                  t0.name AS name, 
                  t0.description AS description, 
                  t0.url_name AS url_name,
                  t0.status_type_id as status_type_id
                FROM 
                  store.store t0 
                WHERE 
                  t0.status_type_id = 2', 
               'resultClass' => '__CLASS__',
               'resultSetMapping' => array('entities' => array('entityClass' => '__CLASS__',
                                                               'fields'      => array('id'           => 'id',
                                                                                      'tracking_url' => 'tracking_url',
                                                                                      'name'         => 'name',
                                                                                      'description'  => 'description',
                                                                                      'url_name'     => 'url_name',
                                                                                      'status_type'  => 'status_type_id')))));
}

这是我对此

的测试的剪辑

public function testNamedNativeQueryPublished()
{
    $results = $this->em->getRepository('MyBundle:Store')->createNativeNamedQuery('published')->execute();

    foreach ($results as $store)
    {
        $this->assertEquals(2, $store->getStatusType());
    }
}
