按天和月分组

Question

我想按生日那样列出我的用户,所以月和日但不是年份.

我有这个问题

SELECT * 
FROM user 
WHERE birthDate IS NOT NULL 
GROUP BY MONTH(birthDate), DAY(birthDate)

但我不知道如何将它与Symfony和Doctrine一起使用.我试过了

$result = $em->getRepository("AcmeApplicationBundle:SecurityServiceUser")
            ->createQueryBuilder('user')
            ->where('user.birthDate IS NOT NULL')
            ->groupBy('MONTH(user.birthDate), DAY(user.birthDate)')
            ->getQuery()
            ->getResult(); 

和

$result = $em->getRepository("AcmeApplicationBundle:SecurityServiceUser")
            ->createQueryBuilder('user')
            ->where('user.birthDate IS NOT NULL')
            ->groupBy('MONTH(user.birthDate)')
            ->groupBy('DAY(user.birthDate)')
            ->getQuery()
            ->getResult(); 

但在这两种情况下我都有错误

[语义错误]第0行,第165行附近'MONTH(birthDate),':错误:无法按未定义的标识或结果变量进行分组.

您尚未为值设置别名.这是一个更新版本:

   $result = $em->getRepository("AcmeApplicationBundle:SecurityServiceUser")
        ->createQueryBuilder('user')
        ->select(' user.username, MONTH(user.birthDate) AS gBmonth, DAY(user.birthDate) AS gBday')
        ->where('user.birthDate IS NOT NULL')
        ->groupBy('gBmonth')
        ->addGroupBy('gBday')
        ->getQuery()
        ->getResult(); 

这应该工作正常.
