如何减去金额

Question

我尝试在sql server中查询但结果未生成

我的查询，表格和预期结果提及

USE [bank] 
GO 

/****** Object: StoredProcedure [dbo].[Pr_Rpt_BankPlaning] ******/ 
SET ANSI_NULLS ON 
GO 

SET QUOTED_IDENTIFIER ON 
GO 

ALTER PRODCEDURE [dbo].[Pr_Rpt_BankPlaning] AS 
BEGIN ;
  WITH cte AS
    ( 
      SELECT 
          TotalAmount, 
          BankAmount,
          (TotalAmount-BankAmount) AS minusamount, 
          rownum = ROW_NUMBER() OVER (order BY BankAmount) 
      FROM Bank AS bc 
    ) 

  SELECT
    CASE
        WHEN cte.TotalAmount = prev.TotalAmount THEN prev.minusamount 
        ELSE cte.TotalAmount 
    END AS TotalAmount1, 
    cte.BankAmount,
    CASE 
        WHEN cte.TotalAmount = prev.TotalAmount THEN prev.minusamount 
        ELSE cte.TotalAmount 
    END
    -cte.BankAmount AS Amount,
    cte.minusamount,
    cte.rownum 
    FROM CTE 
    LEFT JOIN CTE prev ON prev.rownum = CTE.rownum - 1 
    LEFT JOIN CTE nex ON nex.rownum = CTE.rownum + 1 
END

此查询提供此结果

但我希望这种类型的结果在下一个totalamount中结转减去金额

虽然您还没有按照其他人的要求提供任何样本数据，但我使用了第一个屏幕截图中显示的输出作为样本数据来为您提供所需的输出。您需要在查询中集成我的CTE才能获得输出。

以下查询为您提供所需的输出。

DECLARE @AMOUNT_DATA TABLE(TA INT, BA INT,AM INT,MAMT INT,ROWNUM INT )
INSERT INTO @AMOUNT_DATA VALUES
(458800,25000,433800,433800,1),
(433800,25000,408800,433800,2),
(433800,100000,333800,358800,3)

;WITH AMOUNT_DATA
AS
(
    SELECT ROWNUM,TA,BA,TA-BA RESULT FROM @AMOUNT_DATA WHERE ROWNUM=1
    UNION ALL
    SELECT T2.ROWNUM,T1.RESULT TA,T2.BA,T1.RESULT-T2.BA FROM AMOUNT_DATA T1 
    JOIN @AMOUNT_DATA T2 ON T1.ROWNUM=T2.ROWNUM-1
)
    SELECT * FROM AMOUNT_DATA

输出

------------------------------
--ROWNUM    TA  BA  RESULT
------------------------------
1   458800  25000   433800
2   433800  25000   408800
3   408800  100000  308800
------------------------------
