对于下表,我想得到一个显示每个商店中最畅销产品的表格同一产品可能在超过 1 个商店中销量最高。

这是我试过的查询:

SELECT StoreID, ProductID, MAX(Quantity), TotalPrice FROM MyTable GROUP BY StoreID LIMIT 0, 99999;

我得到的答案是:

|StoreID|ProductID|MAX(Quantity)|TotalPrice
'1', '1', '566', '288.0000'
'2', '1', '782', '648.0000'
'3', '1', '473', '172.8000'

问题:我已经检查过,最大数量是正确的
但出于某种原因,即使它不是任何商店中销量最高的产品,它也会为每个产品显示 ID“1”。

对于此表(称为“MyTable”):

|StoreID|TotalPrice|ProductID|Quantity
'1', '288.0000', '1', '167'

( SELECT storeID, MAX(Quantity)
FROM MyTable
GROUP BY storeID
)
