SQL累加查询与sum

Question

我在SQL中有这个查询：

select cast(faturas.datatotal as date) as Dia, faturas.sumF, credito.sumC, isnull(sumF,0)-isnull(sumC,0) as Total
from
(SELECT       SUM([Line Amount]) as sumF, [Posting Date] as datatotal
                               FROM            [CMW$Sales Invoice Line] 
                               where [CMW$Sales Invoice Line].[Posting Date] >= '2017-01-01' 
                               group by [CMW$Sales Invoice Line].[Posting Date]) faturas                   
full outer join
(SELECT        SUM(Amount) as sumC, [Posting Date]
                               FROM            [CMW$Sales Cr_Memo Line] 
                               where [CMW$Sales Cr_Memo Line].[Posting Date] >= '2017-01-01' 
                               group by [CMW$Sales Cr_Memo Line].[Posting Date]) credito                           
on faturas.datatotal=credito.[Posting Date] 

我需要计算累计＆＃34;总计＆＃34;在同一个查询中。我怎么能得到这个？

Answer 1

我用这个解决了我的问题：

sum(isnull(sumF,0)-isnull(sumC,0)) over(order by faturas.datatotal rows unbounded preceding) as Acumulado
