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

AcmeMspadminBundleEntityMspArticle: 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

AcmeMspadminBundleEntityMspChannel: type: entity table: msp_channel oneToMany: Articles: targetEntity: MspArticle mappedBy: Channel

AcmeMspadminBundleEntityMspUser: 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。
