选择最大订单的客户

Question

我有以下简单的表格：

CustomerID  CustomerName   NumOfOrders
1           Joe            15
2           Jane           20
7           Clara          1

我想找到订单数量最多的客户。看起来很琐碎，但我似乎无法找到解决方案。

Answer 1

试试这个：

SELECT
    *
FROM
    my_table
ORDER BY
    NumOfOrders DESC
LIMIT 1

Answer 2

这个怎么样？

SELECT CustomerID, CustomerName, MAX(NumOfOrders) FROM myTable

Demo

Answer 3

select customername, sum(numOfOrders) as cnoo
from myTable
group by customername 
order by cnoo 
limit 1

如果customerName是唯一的（即每个客户只有一行）：

select customername
from myTable
order by numOfOrders desc
limit 1

Answer 4

SELECT CustomerID, NumOfOrders FROM myTable
where  NumOfOrders  =(select MAX(NumOfOrders) FROM myTable)

Answer 5

试试这个......

select top 1 customerName from customer_Order order by numOfOrders desc

Answer 6

您可以使用ORDER BY NumOfOrders DESC LIMIT 1
