Question

我正在使用两个表来显示此数据，其中一个表名为Purchcase_Table，第二个表为Credit_Book。

我想要以下结果：

ID      Date         Descripion    Total  Paid  Balance  Running Balance
------------------------------------------------------------------------
1       28-Jan-17    Purchase      1000   6000  4000     4000
1       29-Jan-17    Purchase      5000   4000  1000     5000
1       30-Jan-17    P.Voucher     5000   2000  3000     3000
1       01-Feb-17    Purchase      9000   4000  5000     8000  
1       02-Feb-17    Purchase      1500   1000  500      8500

请注意P.Voucher条目已经在我们发出信用卡付款凭证时计算总运行余额，因此在运行余额中我们看到“3000”作为运行余额，您可以看到其总数，即上一个条目的总运行余额

到目前为止我尝试的是这个，但没有运气

CREATE PROCEDURE [dbo].[usp_Ledger]
    (@VenId Int)
AS
BEGIN
    DECLARE @Ledger TABLE (ID INT,
                           [DATE] DATETIME,
                           [DESCRIPTION] NVARCHAR(350),
                           TRANSACTION_TYPE NVARCHAR(50),
                           TOTAL DECIMAL(18,2),
                           PAID DECIMAL(18,2),
                           BALANCE DECIMAL(18,2),
                           RUNNING_BALANCE DECIMAL(18,2)
                          )

    INSERT INTO @Ledger
        SELECT 
            [Ven_Id], [Pur_Date], '(PURCHASE)', 'P', 
            [Grand_Total], [Paid], [Balance], 0 
        FROM 
            [dbo].[Purchase_Table] pc
        INNER JOIN 
            [dbo].[Vendor] av ON av.ID = pc.Ven_Id
         /* P REFERS TO PURCHASE TRANSACTION AND CPV REFERS TO CREDIT PURCHASE VOUCHER */

        UNION

        SELECT 
            [VenId], [TransactionDate], '(VENDOR PAYMENT VOUCHER)', 'CPV', 
            [OriginalAmount], [PaidAmount], [RunningBalance], 0 
        FROM 
            [dbo].[Credit_Book] vcb
        INNER JOIN 
            [dbo].[Vendor] av ON av.ID = vcb.VendorId

    SELECT 
        ID, [DATE], [DESCRIPTION],
        TOTAL_AMOUNT, PAID_AMOUNT,
        BALANCE_AMOUNT,

        CASE TRANSACTION_TYPE
           WHEN 'P' 
              THEN LAG([BALANCE_AMOUNT], 1, 0) OVER (ORDER BY [DATE]) + [BALANCE_AMOUNT] 

           WHEN 'CPV' 
              THEN [BALANCE_AMOUNT]
        END AS RUNNING_BALANCE
    WHERE 
        ID = @VendorId 
    ORDER BY 
        [DATE]
END

我得到的结果就是这个

ID      Date         Descripion    Total  Paid  Balance  Running Balance
------------------------------------------------------------------------
1       28-Jan-17    Purchase      1000   6000  4000     4000
1       29-Jan-17    Purchase      5000   4000  1000     5000
1       30-Jan-17    P.Voucher     5000   2000  3000     3000
1       01-Feb-17    Purchase      9000   4000  5000     8000  
1       02-Feb-17    Purchase      1500   1000  500      5500

您可以在最后一个条目中查看其添加的最后余额金额与当前余额金额并显示错误结果。它应该是8500。

我知道我的问题太长了，也可能会让人感到困惑，但以防万一有人为此提供了解决方案。

使用SQL Server存储过程中的两个表计算运行余额
