Symfony2联合查询实现方法

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。
