带AND和OR的查询构建器

Question

我在Symfony 3.4 flex中工作，我需要做一个像这样的查询构建器：

在True AND媒体上“已发布”的所有媒体都是TYPE OF：带有symfony doctrine查询构建器的type AND ((condition 1) OR (condition 2) OR (condition 3))。这两个条件已经成立（已发布，实例为：instance）：

 $queryBuilder = $this->createQueryBuilder('m')
        ->chere('m.published = :published')
        ->andWhere('m INSTANCE OF :instance');

/* 
WHERE m.published = true AND m INSTANCE OF :instance

AND (
    //    ('m.startDate <= :today AND m.endDate >= :today')
    // OR ('m.startDate IS NULL AND m.endDate >= :today')
    // OR ('m.startDate IS NULL AND m.endDate IS NULL')
    // OR ('m.startDate <= :today AND m.endDate IS NULL')
*/

当我尝试这样的事情：

$queryBuilder->andWhere($queryBuilder->expr()->andX(
            $queryBuilder->expr()->lte('m.startDate', ':today'),
            $queryBuilder->expr()->gte('m.endDate', ':today'))
   );

但它不起作用它返回如下：

WHERE (
    (m.published = 1 AND m.type IN (:type)) // I already needed this in all cond
    AND m.start_date <= :today AND m.end_date >= :today // cond 1
)

    OR (m.start_date IS NULL :today AND m.end_date IS NULL) // cond 2
    OR ... // cond 3

所以我在((m.published = 1 AND m.type IN (:type)))的条件不仅需要在所有条件下

你有什么主意吗 ？

谢谢。

你可以这样做：

 $queryBuilder = $this->createQueryBuilder('m')
        ->where("((m.published = true AND m INSTANCE OF :instance) AND
                      (
                          (m.startDate <= :today AND m.endDate >= :today) OR
                          (m.startDate IS NULL AND m.endDate >= :today) OR
                          (m.startDate IS NULL AND m.endDate IS NULL) OR
                          (m.startDate <= :today AND m.endDate IS NULL)
                      )
                 )"
               );

为了您自己的知识，使用DQL，它将是这样的：

//Important to have it initialized alone so you can use it for expressions
$qb=$this->createQueryBuilder('m');

$qb->andWhere($qb->expr()->andX(
    "m.published=1",
    "m INSTANCE OF :instance",
    $qb->expr()->orX(
        $qb->expr()->andX("m.startDate <= :today", "m.endDate >= :today"),
        $qb->expr()->andX("m.startDate IS NULL", "m.endDate >= :today"),
        $qb->expr()->andX("m.startDate IS NULL", "m.endDate IS NULL"),
        $qb->expr()->andX("m.startDate <= :today", "m.endDate IS NULL")
    )
))
->setParameters(array(
    'instance'=>$instance,
    'today'=>$today,
))
->getQuery()
->execute();

它将为您提供以下DQL查询：

SELECT m
FROM AppBundle\Entity\Media m
WHERE m.published=1
    AND m INSTANCE OF :instance
    AND ((m.startDate <= :today AND m.endDate >= :today)
        OR (m.startDate IS NULL AND m.endDate >= :today)
        OR (m.startDate IS NULL AND m.endDate IS NULL)
        OR (m.startDate <= :today AND m.endDate IS NULL))

一些技巧：

永远不要使用where()或orWhere，它有一天会给你带来麻烦 你可以阅读更多关于它here

始终为查询使用双引号。 Doctrine只接受查询中字符串的单引号
