Question

我有3个表用于计算客户的余额，我需要从发票销售金额+发票处理+税金+发票编号相同的表格运输金额总计算余额使用invoice_No然后从表收入中减去金额总和，其中他们具有相同的发票编号，然后+前一个余额，如果以前的发票（前一个发票可以在日期或甚至是Id中找到），则为余额。我希望结果看起来像平衡

InVoiNo Cust SaleAmount Handling Taxes Ship Income Last_Balance Balnce
 A1     A           500      300   200 1295   1000         0.00   1295
 A2     A            50       20    30 1860  15000         1295   1755
 B1     B          1000      100    10 1495    100            0   2505
 C1     C           600      277     0  576   1000         0.00    453
 C2     C           600      300   100  636    500          453   1589

这意味着我想查看并计算上一张发票中每位客户的先前余额这是我的表的架构

试试这个

SELECT
    P.id,
    P.`Date`,
    P.Customer,
    P.SaleAmount,
    P.Handling,
    P.Taxes,
    P.InVoice_No,
    @SHIP:=COALESCE(E.s, 0) AS Shipping,
    @INCOME:=COALESCE(S.s, 0) AS Income,
    @BOL:=P.SaleAmount+ P.Handling+P.Taxes+COALESCE(E.s,0) - COALESCE(S.s,0) AS Balance,
    @sum := if(@cat = P.Customer,@sum,0)+@BOL AS CatTotal,
    @cat := P.Customer

    FROM invoices AS P
    LEFT OUTER JOIN (SELECT
    shipping.Customer,
    shipping.Invoice_no,
    SUM(shipping.Ship_Amount) AS s
    FROM shipping
    GROUP BY shipping.Customer, shipping.Invoice_no
    ) AS E ON P.Customer = E.Customer AND P.InVoice_No = E.Invoice_no
    LEFT OUTER JOIN (SELECT
    income.Customer,
    income.Invoice_No,
    SUM(income.Amount) AS s
    FROM income
    GROUP BY income.Customer, income.Invoice_No
    ) AS S ON P.Customer = S.Customer AND P.InVoice_No = S.Invoice_No



    , (select
    @cat := '',
    @sum := 0
     ) AS InitVarsAlias



    GROUP BY P.InVoice_No, P.Customer, P.`Date`
    ORDER BY P.Customer, P.`Date`
