所以，我有以下查询，
WITH yearlist AS
(
SELECT (year(getdate())+3) AS years
UNION ALL
SELECT y.years - 1 AS years
FROM yearlist y
WHERE y.years - 1 >= (YEAR(GETDATE())-10)
)
SELECT
a.years as [year],
a.CountryName as country,
ISNULL(sum(b.sales), 0) as total
FROM(
SELECT
distinct years
,g.CountryName
FROM
yearlist AS A CROSS JOIN (SELECT
CountryName, salesYear, ISNULL(sum(sales), 0) as total
FROM tblSales where
salesYear BETWEEN (year(getdate())-12) AND (year(getdate()) + 3)
,sales
,salesYear) g
) a left outer join
(SELECT
CountryName, salesYear, ISNULL(sum(sales), 0) as total
FROM tblSales where
salesYear BETWEEN (year(getdate())-12) AND (year(getdate()) + 3)
group by CountryName
,salesYear, sales
) b ON a.CountryName=b.CountryName and a.years=b.salesYear
group by a.CountryName,years
order by years
我得到以下返回：
year country Total

随着时间的推移，我正在努力为每个国家/地区实现累计总数。但是我似乎无法理解。我已经尝试过了：
sum(sales) over (order by salesYear rows unbounded preceding) as total
但这只是用累积总数填充每一行。
我想要的输出如下：
year country Total

我似乎无法让他们单独积累。
答案 0 :(得分：3)
您很可能也需要使用by子句进行分区：
sum(sum(sales)) over (partition by country order by salesYear rows unbounded preceding)
