我有这样的 dql :
$qb = $this->em->createQueryBuilder();
$qb
->select('c.login, c.char_name,c.id,c.sex,c.pvpkills,c.pkkills,c.online,c.online_time,c.last_access,MAX(cs.level) as lvl,sub.name,sub.clan_id')
->from($this->target,'c')
->leftJoin('CharacterSubclass','cs','WITH','c.id = cs.char_id')
->leftJoin('clan','cln','WITH','c.clan_id = cln.id')
->leftJoin('ClanSub','sub','WITH','cln.id = sub.clan_id')
->where('c.clan_id = :id')
->setParameter('id',$id)
->groupBy('c.id')->orderBy('lvl','DESC');
$rs = $qb->getQuery()->getResult();
结果不是对象形式。
array(100)=>{[0]=>array(8){['id']=>'axb' [name]=>'fyz'} [1]=>array{....}}
我尝试过结果映射，但没有希望，浪费时间。 到底有没有办法做到这一点？？？ 我想要这样的结果：
array{[0]=> object(Character)=>{[id]=>'abc' [name]=> 'fyz'....} [1]=>object(Character){...}}
关于学说示例，如果是两个不同的实体：学说本机查询示例
<?php
// Equivalent DQL query: "select u from User u join u.address a WHERE u.name = ?1"
// User owns association to an Address and the Address is loaded in the query.
$rsm = new ResultSetMapping;
$rsm->addEntityResult('User', 'u');
$rsm->addFieldResult('u', 'id', 'id');
$rsm->addFieldResult('u', 'name', 'name');
$rsm->addJoinedEntityResult('Address' , 'a', 'u', 'address');
$rsm->addFieldResult('a', 'address_id', 'id');
$rsm->addFieldResult('a', 'street', 'street');
$rsm->addFieldResult('a', 'city', 'city');
$sql = 'SELECT u.id, u.name, a.id AS address_id, a.street, a.city FROM users u ' .
'INNER JOIN address a ON u.address_id = a.id WHERE u.name = ?';
$query = $this->_em->createNativeQuery($sql, $rsm);
$query->setParameter(1, 'romanb');
$users = $query->getResult();
如果您有这样的实体，您可以使用我正在使用的序列化器jms Serializer：

执行查询后，您可以将数组序列化为对象，如下所示。
$serializer = $this->get('jms_serializer');
$objects = $serializer->fromArray($data, 'array<NameSpace\YourBundle\Entity\Test>');
你将会有一个你想要的东西

class YourDTO
{
public function __construct(
private $login,
private $allYourFields,
...
) {}
}
$qb->select('NEW ' . YourDTO::class . '(c.login, c.char_name,c.id,c.sex,c.pvpkills,c.pkkills,c.online,c.online_time,c.last_access,MAX(cs.level) as lvl,sub.name,sub.clan_id)')
