MS Access 中使用 sum、group by 和 order by 进行 SQL 查询左连接

Question

我正在尝试在 MS Access 中使用

left join

和

sum

、

group by

和

order by

子句执行 SQL 查询。

但结果不正确 - 也许我使用的 SQL 代码是错误的。

DATE        INVONO      TRANSACTION    TOTPRP   TOTPRS  PAYMENT
---------------------------------------------------------------
29-08-2024  SALES-1000  SALES           100000  150000  150000
30-08-2024  SALES-1001  SALES           300000  350000  350000
29-09-2024  SALES-1002  SALES           200000  250000  250000
29-09-2024  SALES-1003  SALES           200000  250000  250000
30-09-2024  SALES-1004  SALES           250000  300000  
30-09-2024  SALES-1005  SALES           250000  300000  

我的询问：

SELECT 
    Invoice.Date AS [DATE],
    SUM(Invoice.TotPRP) AS TOTPRP, 
    SUM(Invoice.TotPRS) AS TOTPRS, 
    SUM(Invoice.PAYMENT) AS PAYMENT, 
    SUM(Expense.Totexp) AS TOTEXP, 
    SUM(Invoice.TotPRS) - SUM(Invoice.TotPRP) AS TOTRESULT,
    SUM(Invoice.PAYMENT) - SUM(Invoice.TotPRS) AS TOTOUTSTANDING,
    SUM(Invoice.PAYMENT) - (SUM(Invoice.TotPRP) + SUM(Expense.TotEXP)) AS TOTPROFITNET
FROM 
    Invoice 
LEFT JOIN 
    Expense ON Invoice.Date = Expense.Date
GROUP BY 
    Invoice.Date, Invoice.INVONO
ORDER BY 
    Invoice.Date;

我的 SQL 查询结果：

日期	TOTPRP	TOTPRS	付款	TOTEXP	全部结果	非常出色	TOTPROFITNET
2024年8月29日	100000	150000	150000	25000	50000	0	25000
2024年9月29日	400000	500000	500000	60000	100000	0	40000
2024年9月29日	400000	500000	500000	60000	100000	0	40000
2024年9月29日	300000	350000	350000	25000	50000	0	25000
2024年9月29日	250000	300000			50000
2024年9月29日	250000	300000			50000

是否可以将字段

date

应用于

period

？

想要的结果

期间	TOTPRP	TOTPRS	付款	TOTEXP	全部结果	非常出色	TOTPROFITNET
8 月 24 日	400000	500000	500000	50000	100000	0	50000
9 月 24 日	900000	1100000	500000	60000	200000	-600000	-460000

WITH InvoiceSummary AS (
    SELECT 
        FORMAT(DATE, 'yy-MMM') AS Period,
        SUM(TotPRP) AS TOTPRP, 
        SUM(TotPRS) AS TOTPRS, 
        SUM(PAYMENT) AS PAYMENT
    FROM 
        Invoice 
    GROUP BY 
        FORMAT(DATE, 'yy-MMM')
),
ExpenseSummary AS (
    SELECT 
        FORMAT(DATE, 'yy-MMM') AS Period,
        SUM(TotEXP) AS TOTEXP
    FROM 
        Expense 
    GROUP BY 
        FORMAT(DATE, 'yy-MMM')
)

SELECT 
    ISNULL(i.Period, e.Period) AS Period,
    ISNULL(i.TOTPRP, 0) AS TOTPRP, 
    ISNULL(i.TOTPRS, 0) AS TOTPRS, 
    ISNULL(i.PAYMENT, 0) AS PAYMENT, 
    ISNULL(e.TOTEXP, 0) AS TOTEXP, 
    ISNULL(i.TOTPRS, 0) - ISNULL(i.TOTPRP, 0) AS TOTRESULT,
    ISNULL(i.PAYMENT, 0) - ISNULL(i.TOTPRS, 0) AS TOTOUTSTANDING,
    ISNULL(i.PAYMENT, 0) - (ISNULL(i.TOTPRP, 0) + ISNULL(e.TOTEXP, 0)) AS TOTPROFITNET
FROM 
    InvoiceSummary i
FULL OUTER JOIN 
    ExpenseSummary e ON i.Period = e.Period
ORDER BY 
    Period;

Result
| Period | TOTPRP  | TOTPRS  | PAYMENT  | TOTEXP  | TOTRESULT | TOTOUTSTANDING | TOTPROFITNET |
|--------|---------|---------|----------|---------|-----------|----------------|---------------|
