想要在SQL Server中按原始和列累計總和

Question

以下是我的實際數據。

select Year,fall_unit,summer_unit,spring_unit 
from (
select 2010 as Year,4 fall_unit,5 summer_unit,6 spring_unit 
union 
select 2011 as Year,7 fall_unit,23 summer_unit,90 spring_unit 
union 
select 2012 as Year,3 fall_unit,2 summer_unit,5 spring_unit) M 

想通過原始&欄也做累計總和。

要求按照以下輸出。

2010 4  9 15 
2011 22 45 135 
2012 138 140 145 

下面是計算的更多解釋。

2010 : 9 = (4+5) 
2010 : 15 = (9+6) 
2011 : 22 = (15+7) 
2011 : 45 = (22+23) 
2011 : 135= (45+90) 
2012 : 138= (135+3) 
2012 : 140= (138+2) 
2012 : 145= (140+5)

嘗試更新後的查詢（最後一個查詢）。我理解的輸出邏輯是：
年| C1：Fall + previous_year_total | C2：秋季+夏季+以前的計數| C3：合計

create table #test(Year int, fall_unit int, summer_unit int, spring_unit int) 

insert #test (Year, fall_unit, summer_unit, spring_unit) 
select 2010 as Year,4 fall_unit,5 summer_unit,6 spring_unit 
union 
select 2011 as Year,7 fall_unit,23 summer_unit,90 spring_unit 
union 
select 2012 as Year,3 fall_unit,2 summer_unit,5 spring_unit 

-- select * from #test 

select t2.Year, 
    case when t1.fall_unit IS NULL then t2.fall_unit 
     else SUM(t1.rowTotal) OVER (ORDER BY t1.YEAR) + t2.fall_unit 
    end as C1, 
    case when t1.summer_unit IS NULL then t2.summer_unit + coalesce(t1.rowTotal, 0) + t2.fall_unit 
     else SUM(t1.rowTotal) OVER (ORDER BY t1.YEAR) + t2.fall_unit + t2.summer_unit 
    end as C2, 
    SUM(t2.rowTotal) OVER (ORDER BY t1.YEAR) as C3 
from (select t.*, t.fall_unit + t.summer_unit + t.spring_unit as rowTotal from #test t) t1 
right join (select t.*, t.fall_unit + t.summer_unit + t.spring_unit as rowTotal from #test t) t2 
on t1.YEAR+1 = t2.YEAR 
order by t2.Year
