请帮助!!!

如何按期间计算PayedManualAmount，期间介于支付之间。所以在第二次付款（325）中，我必须获得5 在第三次支付（500）我必须获得7等等..

if(OBJECT_ID('tempdb..#Amount') IS NOT NULL)
    drop table #Amount

create table #Amount
(
    Date                smalldatetime,
    Disbursement        decimal(18,2),
    PayedManualAmount   decimal(18,2),
    ForPayAmount        decimal(18,2)
)


INSERT INTO #AmountForPay(Date,Disbursement,PayedManualAmount,ForPayAmount) 
VALUES
('20121226',    675.00  ,NULL   ,8.37),
('20121226',    NULL    ,5.00   ,0.00),
('20121227',    NULL    ,NULL   ,0.00),
('20121228',    NULL    ,NULL   ,0.00),
('20130323',    NULL    ,NULL   ,0.00),
('20130324',    NULL    ,NULL   ,0.00),
('20130325',    NULL    ,NULL   ,0.00),
('20130326',    NULL    ,NULL   ,0.00),
('20130327',    325.00  ,NULL   ,4.03),--ForPayAmount = SUM(PayedManualAmount) between 2012-12-26 and 2013-03-26 = 5
('20130328',    NULL    ,4      ,0.00),
('20130329',    NULL    ,NULL   ,0.00),
('20140228',    NULL    ,3      ,0.00),
('20140301',    NULL    ,NULL   ,0.00),
('20140302',    500.00  ,NULL   ,6.20), --ForPayAmount = SUM(PayedManualAmount) between 2013-03-27 and 2014-03-01 = 7

这未经过测试（我甚至不知道它是否在语法上正确，因为我是用SSMS编写的），但这样的事情应该有效：

DECLARE @LastProcessedID INT
SELECT @LastProcessedID = 0

WHILE 1 = 1 BEGIN
    SELECT TOP 1 @CurrentID = ID
    FROM #Amount
    WHERE ID > @CurrentID
    AND Disbursement IS NOT NULL
    ORDER BY ID

    IF @@RowCount = 0 BREAK;

    UPDATE #Amount
    SET ForPayAmount = (SELECT SUM(PayedManualAmount)
                        FROM #Amount
                        WHERE ID < @CurrentID
                        AND ID > @LastProcessedID)
    WHERE ID = @CurrentID

    SELECT @LastProcessedID = @CurrentID
END

请注意，您需要在临时表中添加ID列。您也许可以使用日期列，但我个人只需添加一个标识列。

计算期间之间的金额
