Answer 1

试试这个脚本给你预期的结果

;WITH cte(AcNO,Dates,CheaqueNo,CompanyId,Deposit,Withdraw,Balance)
AS
(
SELECT 2014002,2017-12-19,12500,1,1000.00,0.00,1000.00  Union all
SELECT 30520,2017-11-13,12500,7,0.00,500.00,500.00      Union all
SELECT 50021,2017-10-19,1210,45,2500.00,100.00,2900.00  Union all
SELECT 54201,2017-11-29,121100,22,6000.00,0.00,8900 
)
SELECT * ,(SUM(Deposit)OVER(PArtition by AcNO Order by AcNO)
           +SUM(Balance)OVER(PArtition by AcNO Order by AcNO)
           -SUM(Withdraw)OVER(PArtition by AcNO Order by AcNO)
           )  AS CurrentBalance
FROM cte

结果

AcNO    Dates   CheaqueNo   CompanyId   Deposit Withdraw    Balance CurrentBalance
