我的symfony项目中有两个实体:房屋和软件。
许多家庭可以具有许多软件,许多软件可以属于许多家庭
我正在尝试仅获取具有以下特征的房屋:假设软件n°1 +软件n°2。
实际上,我已经设法检索了拥有软件n°1的房屋和拥有软件n°2的房屋,但并非同时拥有软件1 + soft2的房屋
如果我没记错,应该是内部联接联接,对吧?
这是我的实体和存储库的方法:
class Software {
/**
* @ORM\ManyToMany(targetEntity="App\Entity\Home", mappedBy="softwares")
*/
private $homes;
public function __constuct() {
$this->homes = new ArrayCollection();
}
// ...
public function getHomes(){ ... }
public function addHome(Home $home){ ... }
// ...
}
class Home {
/**
* @ORM\ManyToMany(targetEntity="App\Entity\Software", inversedBy="homes")
*/
private $softwares;
public function __constuct() {
$this->softwares = new ArrayCollection();
}
//...
public function getSoftwares(){ ... }
public function addSoftware(Software $software){ ... }
//...
}
主存储库
class HomeRepository extends ServiceEntityRepository {
public function innerJoinSoftware($softIds)
{
$qb = $this->createQueryBuilder('c')
->innerJoin('c.softwares', 's')
->andWhere('s.id IN(:softIds)')
->setParameter('softIds', $softIds)
;
return $qb->getQuery()->getResult();
}
}
为了说明我的观点:
Home1具有soft1,soft2
Home2具有soft1,soft3
Home3具有soft2,soft3
我想做的是
dump(homeRepo->innerJoinSoftware([1, 2]));
//should output Home1 but actually I have
//it outputs Home1, Home2, Home3
这是我发布的SQL版本,但是我仍然无法使用Doctrine完成
SELECT home.id, home.name FROM Home as home
INNER JOIN (
SELECT home_id as home_id, COUNT(home_id) as count_home
FROM home_software
WHERE software_id IN (1, 2)
GROUP BY home_id
HAVING count_home = 2) as soft # count_home should be dynamic
ON home.id = soft.home_id
ORDER BY home.name
答案 0 :(得分:0)
这是我解决此问题的方法(在我发布的原始SQL的帮助下)
public function findBySoftwaresIn($softIds)
{
//retrieve nbr of soft per home
$nbrSoftToFind = count($softIds);
$qb = $this->createQueryBuilder('h');
$qb->innerJoin('h.softwares', 's')
->andWhere('h.id IN (:softIds)')
->setParameter('softIds', $softIds)
//looking for home coming back by nbrSoft
->andHaving($qb->expr()->eq($qb->expr()->count('h.id'), $nbrSoftToFind))
->groupBy('h.id')//dont forget to group by ID
->addOrderBy('h.name')
;
return $qb->getQuery()->getResult();
}
