如何按创建的列分组？

Question

$qb = $this->createQueryBuilder('o')
            ->select('u.id as user_id', 'u.username as username', 'u.companyName', 'month(o.checkedAt) as month', 'identity(l.productCategory) as product_category',
                'a.street', 'a.zip', 'a.apartmentNo', 'a.city', 'a.streetNo')
            ->join(User::class, 'u', Join::WITH, 'o.user = u')
            ->join(UserAddress::class, 'a', Join::WITH, 'u.id = a.user')
            ->join(OrderLens::class, 'l', Join::WITH, 'l.order = o.id')
            ->groupBy('o.user')
            ->addGroupBy('month');
[...]

我收到通知：未定义索引：月 如何按这两个变量对记录进行分组？ 没有 ->groupBy('month') 它可以 100% 正确工作

编辑：我没有看到您已经添加了month(o.checkedAt) as month，您可以删除我之前所说的内容，然后使用另一个别名编辑您的 addGroupBy。

更改您的 month(o.checkedAt) 使用的别名

$qb = $this->createQueryBuilder('o')
            ->select('u.id as user_id', 'u.username as username',
               'u.companyName', 'month(o.checkedAt) as cMonth', 
               'identity(l.productCategory) as product_category',
               'a.street', 'a.zip', 'a.apartmentNo', 'a.city', 'a.streetNo')
            ->join(User::class, 'u', Join::WITH, 'o.user = u')
            ->join(UserAddress::class, 'a', Join::WITH, 'u.id = a.user')
            ->join(OrderLens::class, 'l', Join::WITH, 'l.order = o.id')
            ->groupBy('o.user')
            ->addGroupBy('cMonth');
