[英]How do I add a proper Doctrine Query builder and Join a table
I am trying to build this SQL query into query builder but when adding a join, it breaks. 我正在尝试将此SQL查询构建到查询生成器中,但是在添加联接时会中断。 If I take out join it works but there are the item's in Join that id like to have access to.
如果我退出加入,则可以使用它,但是在加入中有该项目的ID可以访问。
I have tried different methods of using query builder, I have read the documentation and follow its instructions but its not working. 我尝试了使用查询生成器的其他方法,已经阅读了文档并按照其说明进行操作,但不起作用。
Here is my SQL query 这是我的SQL查询
SELECT * FROM invoice i
JOIN item it
WHERE i.created_at >= '2019-03-26 08:00:00' and
i.created_at <= '2019-03-26 08:05:00' and i.status=2;
Here is my Query builder inside Symfony. 这是我在Symfony中的查询生成器。
/** @var \Doctrine\ORM\EntityManager $em *
$em = $container->get('doctrine')->getManager();
$em->getConnection()->getConfiguration()->setSQLLogger(null);
/** @var EntityRepository $repository */
$repository = $em->getRepository('GivingBundle:Invoice');
/** @var QueryBuilder $qb */
$qb = $repository->createQueryBuilder('i');
$qb->join('i.item', 'it')
->Where($qb->expr()->between('i.created_at', ':starts_at', ':ends_at'))->andWhere('i.status = 1')
->setParameter('starts_at',$startsAt,\Doctrine\DBAL\Types\Type::DATETIME)
->setParameter('ends_at', $endsAt,\Doctrine\DBAL\Types\Type::DATETIME)
;
$query = $qb->getQuery();
$results = $query->getResult();
However, I am getting an error (below) 但是,我收到一个错误(如下)
Doctrine\ORM\Query\QueryException]
[Semantical Error] line 0, col 66 near 'it WHERE (i.created_at':
Error: Class KCM\GivingBundle\Entity\Invoice has no association
named item
What id like to do is select the Invoice table base along with the Item table so I can access both of its properties. id要做的是选择“发票”表库和“项目”表,以便我可以访问其两个属性。 I am trying to create a Symfony command that runs an SQL query, report results for items in status 2 and eventually adds it as a cronjob.
我正在尝试创建一个运行SQL查询的Symfony命令,报告状态2中项目的结果,并最终将其添加为cronjob。
Can you show code for associations in your entity? 您可以显示实体中关联的代码吗? From your question it looks like, it should be something like
从您的问题来看,它应该像
/** @Entity */
class Invoice
{
// ...
/**
* This is the inverse side.
* @OneToMany(targetEntity="Items", mappedBy="invoice")
*/
private $items;
// ...
public function __construct() {
$this->items= new ArrayCollection();
}
}
/** @Entity */
class Items
{
// ...
/**
* This is the owning side.
* @ManyToOne(targetEntity="Invoice", inversedBy="items")
* @JoinColumn(name="invoice_id", referencedColumnName="id")
*/
private $invoice;
// ...
}

I did not see a join in your QueryBuilder code, did you just forget it here or is that the error? 我在您的QueryBuilder代码中没有看到联接,您只是在这里忘记了联接还是那是错误? I wrote a function below how it would work in my case, but something along these line should help you.
我在下面的情况下编写了一个函数,但是遵循这些原则可以为您提供帮助。 I did not see a join condition in your plain sql so I assumed the column names are the same.
我在您的普通sql中没有看到连接条件,因此我假设列名相同。 If the Query is working but the error consists then take a look at the annotations in your entity, you probably need something like
如果查询正常但错误仍然存在,请查看您实体中的注释,您可能需要类似
in your entities. 在您的实体中。 (Like already said by @Azhar Khattak)
(就像@Azhar Khattak已经说过的那样)
public function findInvoice($dateFrom, $dateTo)
{
$qb = $this->em->createQueryBuilder();
$qb->select('i')
->from(Invoice::class, 'i')
->join(Item::class, 'it', Join::WITH, 'i.created_at = it.created_at')
->where($queryBuilder->expr()->between('r.created_at', ':datefrom', ':dateto'))
->andWhere($qb->expr()->eq('i.status', 1))
->setParameters(['datefrom' => $dateFrom, 'dateto' => $dateTo])
return $qb->getQuery()->getResult();
}
