sql to doctrine查询语言

Question

如何将此sql写入doctrine查询语言（DQL）？

SELECT * 
FROM service 
WHERE service.id NOT IN (SELECT id_service FROM reclamation)

感谢。

Answer 1

尝试使用不存在：

SELECT * 
FROM service 
WHERE NOT Exists (SELECT 1 FROM reclamation WHERE id_service = service.id)

Answer 2

尝试这样做，

$em = $this->getDoctrine()->getManager();

$query = $em->createQuery(
             'SELECT s 
              FROM YourBundle:Service s
              WHERE s.id NOT IN 
                 ( SELECT s.idService FROM YourBundle:Reclamation r )'
            )->getResult();

如果值得，你可以使用旧学校的方式！ native-sql-with-docrtine

Answer 3

请参阅链接http://doctrine.readthedocs.org/en/latest/en/manual/dql-doctrine-query-language.html#subqueries

$q = Doctrine_Query::create()
    ->select('s')
    ->from('Service s')
    ->where('s.id NOT IN (SELECT id_service FROM reclamation)
    ->getQuery()
    ->getResult();
