[英]Doctrine where clause with an array
I have an entity called "invoice" with many "subscription" such that "invoice" and "subscription" are in a many to many relationship. 我有一个名为“发票”的实体,其中包含许多“订阅”,因此“发票”和“订阅”之间存在多对多关系。
class Invoice
{
/**
* @ORM\Column(type="integer")
*/
protected $a;
/**
* @ORM\Column(type="integer")
*/
protected $b;
/**
* @ORM\ManyToMany(targetEntity="Subscription", inversedBy="invoices")
*/
protected $subscriptions;
public function __construct()
{
$this->subscriptions = new ArrayCollection();
}
//typical setters and getters
}
Using the querybuilder, how do I get a set of matching entities using the where clause on subcription? 使用querybuilder,如何使用子预订的where子句获取一组匹配的实体?
$subscription = ;//something pulled from the db and is a "subscription" object
$em->createQueryBuilder()
->select('p')
->from('Invoice', 'p')
->where('p.a = :a')
->andWhere('p.b = :b')
->andWhere('p.subscriptions has :subscription') //this line here I need help
->setParameter('a', 1)
->setParameter('b', 2)
->setParameter('subscription', $subscription)
->getQuery()
->getResult();
Doctrine have special statement MEMBER OF
for this aim. 学说有特别声明MEMBER OF
为这一目标。 Another solution is to make subquery. 另一个解决方案是进行子查询。
->andWhere(':subscription MEMBER OF p.subscriptions')
Examples you can find in official doctrine documentation . 您可以在官方学说文档中找到示例。
I'm not entirely sure, but perhaps you should join subscriptions. 我不确定,但是也许您应该加入订阅。
$subscription = ;//something pulled from the db and is a "subscription" object
$em->createQueryBuilder()
->select('p')
->from('Invoice', 'p')
->join('p.subscriptions', 'subscription');
->where('p.a = :a')
->andWhere('p.b = :b')
->andWhere('subscription = :subscription') //this line here I need help
->setParameter('a', 1)
->setParameter('b', 2)
->setParameter('subscription', $subscription)
->getQuery()
->getResult();
Alternatively, if subscription has an id, you can use that instead of the object. 或者,如果预订具有ID,则可以使用该ID代替该对象。
