资产负债表报告的动态 T-SQL 数据透视查询

如何解决资产负债表报告的动态 T-SQL 数据透视查询

我的任务是构建资产负债表报告，我已经构建了下面的数据透视查询，但我发现了一些挑战：

1 - 报告应基于可变日期运行，这意味着例如列 [2021-01-31] 应将所有历史数据带到 31/01/2021，以及以下列 [2021-02-28] ] 应该将所有历史数据带到 28/02/2021，目前我只能填充第二列

2 - 日期列应该是动态的，因此如果在 3 月份，列 [2021-03-31] 将自动添加

有什么方法可以实现我的要求吗？

热烈的问候， 丹尼尔

DECLARE 

@to_date DATETIME


SET @to_date = (select eomonth( getdate()))



select "Classification","Account Name",[2021-01-31],[2021-02-28]

from
(

        select
        'Assets' as "Group Mask",case when t0.FatherNum = 'A20' then 'AR' 
        when t0.FatherNum in ('A40','A50') then 'OCA' 
        when t0.FatherNum = 'A90' then 'FA'
        when t0.FatherNum = 'A10' then 'CASH'
        else 'Other' end as "Classification",@to_date as "Date",t0."AcctName" "Account Name",case when t1.RefDate <= @to_date then  SUM(t1."Debit") - sum(t1."Credit") end as Balance


        FROM OACT t0 -- G/L Accounts

        inner join JDT1 t1 ON T0."AcctCode" = T1."Account"

        where t0."GroupMask" = 1
        

        group by
        t0."AcctName",t0.FatherNum,t1.RefDate,t1."Account"


    ) as t

    pivot(
        sum(Balance)
        for "Date" in ([2021-01-31],[2021-02-28]))
    as pivot_table

解决方法

我又修改了我的答案。这将根据您的需要计算小于当月的每个日期的累计余额。请检查并告诉我。
