本文实例讲述了Symfony2联合查询实现方法。分享给大家供大家参考，具体如下：

1.yml文件

Acme\MspadminBundle\Entity\MspArticle:
 type: entity
 table: msp_article
 manyToOne:
 Channel:
 targetEntity: MspChannel
 inversedBy: Articles
 joinColumn:
 name: channel_id
 referencedColumnName: channel_id
 User:
 targetEntity: MspUser
 inversedBy: Userone
 joinColumn:
 name: user_id
 referencedColumnName: user_id

Acme\MspadminBundle\Entity\MspChannel:
 type: entity
 table: msp_channel
 oneToMany:
 Articles:
 targetEntity: MspArticle
 mappedBy: Channel

Acme\MspadminBundle\Entity\MspUser:
 type: entity
 table: msp_user
 oneToMany:
 Userone:
 targetEntity: MspArticle
 mappedBy: User

2.查询代码：

$sql="SELECT a.id,a.checkStatus,a.title,a.releaseSysDate,
 a.visitTotal,u.userName ,n.name FROM AcmeMspadminBundle:MspArticle a
 JOIN a.User u JOIN a.Channel n";
$query = $emt->createQuery($sql." Where a.checkStatus = 0 ");
$mspArtile = $query->getResult();

希望本文所述对大家基于Symfony框架的PHP程序设计有所帮助。
