Question

我使用Symfony 2.4.2我有两个Doctrine实体。名称：城市和城镇。

关系结构：

城市 - ＆gt; Town = OneToMany 镇 - ＆gt; City = ManyToOne

实体/ City.php

/**
 * @ORM\OneToMany(targetEntity="Town", mappedBy="city")
 */
private $towns;

实体/ Town.php

/**
 * @ORM\ManyToOne(targetEntity="City", inversedBy="towns")
 * @ORM\JoinColumn(name="city_id", referencedColumnName="id")
 */
private $city;

其中In Query未在第二和第三项中运行。

1-）Town =＆gt; City Query（Working）Profiler SS：http://prntscr.com/34lx9q

$query = $this->_entityManager->createQuery('SELECT town FROM PersonalSiteBundle:Town town');
$query->setFetchMode(
    'Personal\SiteBundle\Entity\Town',
    "city",
    \Doctrine\ORM\Mapping\ClassMetadata::FETCH_EAGER
);
$query->execute();

2-）Town =＆gt;城市查询（不工作）Profiler SS：http://prntscr.com/34ly4h

$query = $this->_entityManager->createQuery('SELECT town FROM PersonalSiteBundle:Town town');
$query->setFetchMode(
    'Personal\SiteBundle\Entity\Town',
    "city",
    \Doctrine\ORM\Mapping\ClassMetadata::FETCH_EAGER
);
$query->execute(array(),Query::HYDRATE_ARRAY);

3-）City =＆gt; Town Query（Not Working）Profiler SS：http://prntscr.com/34ly4h

$query = $this->_entityManager->createQuery('SELECT city FROM PersonalSiteBundle:City city');
$query->setFetchMode(
    'Personal\SiteBundle\Entity\City',
    "towns",
    \Doctrine\ORM\Mapping\ClassMetadata::FETCH_EAGER
);
$query->execute(array(),Query::HYDRATE_ARRAY);

Answer 1

如果要在存储库中执行此操作，可以执行JOIN并将资源添加到所选对象。

这是QueryBuilder版本：

ALTER TABLE car_table MODIFY price decimal(10,3) AFTER color;

Symfony2 Doctrine Eager在查询中加载
