每张帐单的付款在不同的日期分期付款，如上所示。每次支付部分账单时如何查找剩余的账单金额？

我使用了以下查询：

SELECT siph.SupplyPaymentID,si.SupplyInvoiceID, 
       siph.DateOfPayment,si.TotalBill, siph.BillPaidAmount,
       si.TotalBill - SUM(siph.BillPaidAmount) over(order by siph.SupplyPaymentID asc) as RemainingBillAmount,
       siph.PaymentMode 
from SupplyInvoicePaymentHistory siph inner join 
     SupplyInvoice si 
     on siph.SupplyInvoiceID = si.SupplyInvoiceID

但是它仅适用于第一个SupplyInvoiceID的账单付款。输入第二个及以后的SupplyInvoiceID的帐单付款时，我得到以下错误结果：

 PaymentID  SupplyInvoiceID   Date     TotalBill   BillPaidAmount    Remaining Bill

    1           1              05-04-2018   2,10,000    20,000             1,90,000
    2           1              10-05-2018   2,10,000    60,000             1,30,000
    3           1              13-06-2018   2,10,000    1,30,000           0 
    4           2              10-05-2018   80,000      40,000             -1,70,000
    5           2              13-06-2018   80,000      20,000             -1,90,000  
    6           2              15-06-2018   80,000      20,000             -2,10,000

..请帮助找到上述问题第一段中列出的正确结果。

Answer 1

您需要在PARTITION BY中添加sum() over ()子句，以使其成为每个发票ID的累积金额。

将此添加到您的RemainingBillAmount列：

... - SUM(...) over (partition by si.SupplyInvoiceID ...)

整个查询：

SELECT siph.SupplyPaymentID,si.SupplyInvoiceID, 
       siph.DateOfPayment,si.TotalBill, siph.BillPaidAmount,
       si.TotalBill - SUM(siph.BillPaidAmount) over(partition by si.SupplyInvoiceID order by siph.SupplyPaymentID asc) as RemainingBillAmount,
       siph.PaymentMode 
from SupplyInvoicePaymentHistory siph inner join 
     SupplyInvoice si 
     on siph.SupplyInvoiceID = si.SupplyInvoiceID

查询以在SQL Server中查找“每次支付相应的账单后的余额”
