Symfony原则DQL如何将SELECT添加到主SELECT的总和中

实际上，我想用这个常规SQL查询重现：

SELECT SUM(b.nb_places * (SELECT pricing FROM param p WHERE t.date BETWEEN p.from_date AND p.to_date)) as gains from booking b INNER JOIN tour t ON b.tour_id = t.id;

根据两个日期之间的价格计算总收益

我在存储库中编写了这个DQL：

    public function allBooking() {
        $query = $this->manager->createQuery(
            'SELECT 
                 SUM(b.nbPlaces * SELECT p.pricing FROM \App\Entity\Param p WHERE t.date BETWEEN p.fromDate AND p.toDate)
        FROM App\Entity\Booking b JOIN b.tour t'
    );
    return $query->getResult();
}

但运行此查询时，我得到：

[Syntax Error] line 0, col 24: Error: Expected Literal, got 'SELECT' (500 Internal Server Error)

如何使用DQL或QueryBuilder实现此查询

Thx请求帮助

您忘记了放置

SELECT p.pricing FROM \App\Entity\Param p WHERE t.date BETWEEN p.fromDate AND p.toDate

添加到其他括号中

应该是这样的：

$query = $this->manager->createQuery(
    'SELECT SUM(b.nbPlaces * (SELECT p.pricing FROM \App\Entity\Param p WHERE t.date BETWEEN p.fromDate AND p.toDate))
    FROM App\Entity\Booking b JOIN b.tour t'
);

我很震惊，这不起作用。。。即使有了这次更新，我也犯了同样的错误。根据其他一些调查，似乎这种查询在理论上是不可能的，必须回到原始查询来实现
