Eloquent 排序依据和分组依据

Question

我已经搜索了 2 个小时，了解如何使用 groupBy 和 orderBY 通过 eloquent 构建查询。

这是我的情况：我有一个 table 订单包含这些列：

idOfOrder, quantityOfProduct, userWhoBuy, productBuy, statusOfOrder

我想获得销量最高的 3 个产品。为此，我需要构建一个查询，该查询对来自 ProductBy 的所有数据进行分组，根据数量对主题求和，并按 desc 对主题进行排序。但这太难了。

这是我的实际查询：

    $buyObj->select('product',DB::raw('count(*) as total'))
->where('status','=','1')
->groupBy('product')
->orderBy('quantity','desc')
->take(3)
->get();

我收到这个错误：

SQLSTATE[42000]: Syntax error or access violation: 1055 Expression #1 of ORDER BY clause is not in GROUP BY clause and contains nonaggregated column 'web_projet_exia.buys.quantity' which is not functionally dependent on columns in GROUP BY clause; this is incompatible with sql_mode=only_full_group_by (SQL: select product, count(*) as total from buys where status = 1 group by product order by quantity desc limit 3) "

你知道怎么解决吗？

提前致谢！

解决办法就是只按总数订购，而不是按数量订购。感谢@JonasStaudenmeir
