Error: Expected Doctrine\ORM\Query\Lexer::T_IDENTIFIER, got '*'

Question

我正在尝试从 symfony 中的嵌套树结构生成一个 JSON 文件。 它用于 jquery-fancytree。因此，我正在处理 sql 查询。

但是我的 RolesRepository 给出了
错误：应为 Doctrine\ORM\Query\Lexer::T_IDENTIFIER，得到“*”

SQL 手动查询有效

class RolesRepository extends \Doctrine\ORM\EntityRepository
{


    public function getNestedToJSON()
    {
        $em = $this->getEntityManager();
        $query = $em->createQuery(
            'SELECT n.* , round((n.Rght-n.Lft-1)/2,0) AS offspring,
              count(*)-1 + (n.Lft>1) AS level,
              ((min(p.Rght)-n.Rght-( n.Lft >1 ))/2) > 0 AS lower,
              (((n.Lft-max(p.Lft)>1))) AS upper 
              FROM md_roles n, md_roles p 
              WHERE n.Lft BETWEEN p.Lft AND p.Rght 
              AND (p.id != n.id OR n.Lft = 1) 
              GROUP BY n.id 
              ORDER BY n.Lft')
            ->getResult();


        return $query;


    }
}

有人知道为什么吗？

您尝试执行 SQL 但此函数需要一个 DQL 字符串。而是将 $em->createNativeQuery() 用于普通 SQL 语句或将您的 SQL 转换为等效的 DQL 表达式。
