存储过程中的账本报告逻辑

我有一个名为“患者分类帐报告”的存储过程，我需要在其中显示患者的日常交易详细信息和余额金额。我正在为您提供以下代码中的一个采样数据，这些数据是如何插入到我的临时表中的sp。

create table #Patient_ledger (PATIENT_NAME varchar(250),PATIENT_NBR bigint,BILLNO varchar(250),BILLAMOUNT bigint,
PAID_AMOUNT bigint)

Insert into #Patient_ledger (Patient_name ,Patient_nbr ,billno ,billamount ,
paid_amount )

select 'ABC',1,'DUE_BILL_ABC_1',100,50
union all
select 'ABC',1,'DUE_BILL_ABC_2',160,90
UNION ALL
select 'ABC',1,'DEPOSIT_BILL_ABC',0,60
UNION ALL
select 'XYZ',2,'DEPOSIT_BILL_XYZ',0,70
UNION ALL
select 'XYZ',2,'DUE_BILL_XYZ_1',100,30

SELECT * FROM #Patient_ledger

Drop table #Patient_ledger

我想如何在报告中显示数据。

 PATIENT_NUMBER   BILLNO         BILLAMOUNT  PAID_AMOUNT  BALANCE

    1          DUE_BILL_ABC_1      100         50            50  --(100-50)     
    1          DUE_BILL_ABC_2      160         90            120  --(160-90 +50(Here 50 is prev balance amount of same patient))
    1          DEPOSIT_BILL_ABC     0          40            80 ---( 120-40=80)
    2          DEPOSIT_BILL_XYZ     0          70            0        
    2          DUE_BILL_XYZ_1      100         30            0  --Here Balance is zero because  patient has deposited some      
                                                                 --amount before bill (70-100+30=0)      

Note: Balance amount should deduct when deposits are paid by that particual patient.

我已经尝试过如下可能对你有帮助

SELECT Patient_nbr,
       billno,
       billamount,
       PAID_AMOUNT,
       CASE
         WHEN RNO > 1 THEN Sum(billamount - PAID_AMOUNT)
                             OVER(
                               PARTITION BY Patient_nbr
                               ORDER BY RNO)
         ELSE Iif(( billamount - PAID_AMOUNT ) < 0, 0, billamount - PAID_AMOUNT)
       END
FROM   (SELECT *,
               Row_number()
                 OVER(
                   PARTITION BY Patient_nbr
                   ORDER BY Patient_nbr) AS RNO
        FROM   #Patient_ledger) A
