每个帐号的结余

Question

我需要每个帐号都有未清余额。

我尝试开发一个函数，但是总是得到错误的值。

请参见下面的示例数据以及我目前如何计算运行余额：

declare @tbl table (id int primary key identity, Sort varchar(100), MasterAccount varchar(50), SubAccount varchar(50), Amount float)
insert into @tbl (Sort,MasterAccount,SubAccount,Amount)
values
('1000_1','1000','aaOpening Balance',78137.58)

,('2000_3','2000','zzClosing Balance',208779.28)


select
*
,   round(case SubAccount when 'zzClosing Balance' then 0 else sum(Amount) over(order by [Sort] rows unbounded preceding) end,2) RunningBalance
from    @tbl

结果如下：

我面临的问题是第二个帐户的余额（在这种情况下，帐户编号为“ 2000”）的计算错误。

我需要运行余额以值128,023.65开头并以208,779.28结尾。

为了给您一个更好的主意，我的预期结果将如下所示：

我将如何获得预期的结果？

非常感谢您的协助！

Answer 1

我尝试对运行余额进行分区，但无法正确完成。

我一直努力，终于做到了。

我将运行平衡脚本更改为此，并且它起作用了：

select
*
,   round(case SubAccount when 'zzClosing Balance' then 0 else sum(Amount) over(partition by MasterAccount order by Sort rows unbounded preceding ) end,2) RunningBalance
from    @tbl

谢谢您的帮助。
