Question

    return $this->entityManager
        ->createQueryBuilder()
        ->select('cac.fkClient', 'cac.fkIndividualConsultation', 'cac.dateAdded', 'cac.fkWorker')
        ->from(ClientActivityIndividualConsultationHistory::class, 'cac')
        ->where('cac.dateAdded BETWEEN :startDate AND :endDate')
        ->andWhere('cac . fkWorker = :workerId')
        ->setParameters([
            'startDate' => $dateStart,
            'dateEnd' => $dateEnd,
            'workerId' => $workerId
        ])
        ->getQuery()
        ->getArrayResult();

错误讯息：

[语义错误]第0行，第11行靠近fkClient， cac.fkIndividualConsultation，＆＃39;：错误：无效的PathExpression。一定是一个StateFieldPathExpression。

    </entity>

我尝试了所有东西（stackoverflow，谷歌，自己的expierences），但我真的不知道哪里可能有问题。有人可以解释我这个错误或导航我的正确方法吗？谢谢。

我不想使用IDENTITY函数，因为我需要所有与外键相关的数据。（Doctrine自动选择这些对象，我认为这会产生错误，但为什么呢？）

使用：Symfony FW，Doctrine 2 ORM，MySQL

我的提示：

错误的ORM生成文件
QueryBuilder错误

Answer 1

你应该加入 fkClient，fkIndividualConsultation和fkWorker关系，以便选择它们。

所以改为：

<div class="modal" id="Gallerie">
    <div class="modal-dialog modal-dialog-centered" role="document">
        <div class="modal-content">
            <div id="carouselExampleControls" class="carousel slide" data-ride="carousel">
                <div class="carousel-inner">
                    <div class="carousel-item active">
                        <img class="d-block w-100" src="http://placehold.it/400x300" alt="First slide">
                    </div>
                    <div class="carousel-item">
                        <img class="d-block w-100" src="http://placehold.it/400x300" alt="Second slide">
                    </div>
                    <div class="carousel-item">
                        <img class="d-block w-100" src="http://placehold.it/400x300" alt="Third slide">
                    </div>
                </div>
                <a class="carousel-control-prev" href="#carouselExampleControls" role="button" data-slide="prev">
                    <span class="carousel-control-prev-icon" aria-hidden="true"></span>
                    <span class="sr-only">Previous</span>
                </a>
                <a class="carousel-control-next" href="#carouselExampleControls" role="button" data-slide="next">
                    <span class="carousel-control-next-icon" aria-hidden="true"></span>
                    <span class="sr-only">Next</span>

</div>

Answer 2

   return $this->entityManager
                ->createQueryBuilder()
                ->select('cac')
                ->distinct('cac.fkClient')
                ->from(ClientActivityIndividualConsultationHistory::class, 'cac')
                ->where('cac.dateAdded BETWEEN :startDate AND :endDate')
                ->andWhere('cac . fkWorker = :workerId')
                ->setParameters([
                    'startDate' => $dateStart,
                    'endDate' => $dateEnd,
                    'workerId' => $workerId
                ])
                ->getQuery()
                ->getResult();

固定。

使用 getResult（）函数代替getArrayResult（）;

谢谢大家。

Answer 3

您可以按以下方式选择语句：

SELECT IDENTITY(c.parent) ...

它将返回ID，然后您可以按照以下方法在getResult（）方法中将其与对象混合：

->getResult(AbstractQuery::HYDRATE_OBJECT);

错误：无效的PathExpression。通过Doctrine选择查询后必须是StateFieldPathExpression
