如何将总和值添加到每一行？

Question

下面是我的桌子：

id  order_number    order_date  order_details
---------------------------------------------
1      222          01-01-2020       44
2      222          02-01-2020       66
3      222          03-01-2020       20
4      223          03-01-2020       33
5      224          04-01-2020       55
6      225          02-01-2020       77

我想要 sum(order_details) where order_number = 222

喜欢这张桌子

order_date       sum_order_details
----------------------------------
01-01-2020       130
02-01-2020       130
03-01-2020       130

我尝试了以下方法，但它不起作用

select  order_number , order_date , sum(order_details) sum_orders from ex
group by order_number
having order_number = 222

Answer 1

它似乎就像你在这是一个窗口 SUM:

SELECT order_date,
       SUM(order_details) OVER () AS sum_orders
FROM YourTable
WHERE order_number = 222;
