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。
