Doctrine DQL Date作为参数问题

Question

嗨,我有一个可行的DQL(我从一开始就得到了所有的事件):

DoctrineHelper::getEntityManager()->createQueryBuilder()
    ->select("u.surname, count(u.surname) as total")
    ->from("User", "u")
    ->from("AbstractEvent", "e")
    ->from("Attendance", "a")
    ->where("u = a.attendee")
    ->andWhere("e = a.event")
    ->andWhere("a.status=1")
    ->andWhere("e.date<CURRENT_TIMESTAMP()")
    ->groupBy("u.email")
    ->orderBy("total","desc");

但这个没有(我只想这个月的活动):

DoctrineHelper::getEntityManager()->createQueryBuilder()
    ->select("u.surname, count(u.surname) as total")
    ->from("User", "u")
    ->from("AbstractEvent", "e")
    ->from("Attendance", "a")
    ->where("u = a.attendee")
    ->andWhere("e = a.event")
    ->andWhere("a.status=1")
    ->andWhere("e.date<CURRENT_TIMESTAMP()")
    ->andWhere("e.date>?", date('Y-m-d 00:00:00', strtotime('-'.(date('j')-1).' day')) )
    ->groupBy("u.email")
    ->orderBy("total","desc");

我的error.log有这一行:

 #0 /var/www/Doctrine/ORM/Query/AST/InputParameter.php(46): Doctrine\\ORM\\Query\\QueryException::invalidParameterFormat('?')

这个日期的print_r给了我:2011-08-01 00:00:00这是正确的.

这是日期的映射:

/**
     * Date of the event.
     * @Column(type="datetime")
     */
    private $date;

任何帮助表示感谢!

使用查询参数,然后将DateTime对象设置为参数的值.然后,Doctrine将自动处理转换.

这是我自己项目中的示例代码

    $builder = $this->getEntityManager()->createQueryBuilder();
    $builder->select('a')
        ->from('MaggotsLeadGeneratorBundle:JobApplication', 'a')
    ;

    $and = $builder->expr()->andX();
    if ($dateFrom) {
        $and->add($builder->expr()->gt('a.ctime', ':dateFrom'));
        $builder->setParameter('dateFrom', $dateFrom);
    }

    if ($dateTo) {
        $and->add($builder->expr()->lt('a.ctime', ':dateTo'));
        $builder->setParameter('dateTo', $dateTo);
    }

    $builder->where($and);
    $query = $builder->getQuery();

    $result = $query->getResult();

无法让它与参数一起使用,所以这就是我最终的结果:

$now = new DateTime;
$now->modify( '-'.(date('j')-1).' day' );

$qb = DoctrineHelper::getEntityManager()->createQueryBuilder()
                        ->select("u.surname, count(u.surname) as total")
                        ->from("User", "u")
                        ->from("AbstractEvent", "e")
                        ->from("Attendance", "a")
                        ->where("u = a.attendee")
                        ->andWhere("e = a.event")
                        ->andWhere("a.status=1")
                        ->andWhere("e.date<CURRENT_TIMESTAMP()")
                        ->andWhere("e.date > '".$now->format("Y-m-d H:i:s")."'")
                        ->groupBy("u.email")
                        ->orderBy("total","desc");
