收支计算

Question

我需要显示每天的收入和支出

收支表不同

例如，我需要以以下格式显示：

17/08/2019日期表中有两个收入

我需要计算当日的收入总和，并在当日费用中显示在结果上。

我已经尝试了一些查询，但是没有用。

Date |  Income | Expense | Profit 

Select SUM(d.amount)
     , SUM(e.amount)
     , d.date
     , e.date 
  FROM due d 
  JOIN expenses e
    ON d.date = e.date

费用表-table-name：费用

id | date      |  details  |  amount
1   13-08-2019     daily      50
2   17-08-2019     cleaning   50
3   17-08-2019     cleaning   50
4   18-08-2019     Tea        150 
5   18-08-2019     other      50 

收入表-table-name：到期

id | date         |  amount
4   12-08-2019        150
5   13-08-2019        100 
6   18-08-2019        450
7   18-08-2019        50 

结果将是：

id | date       | Income | Expense | Profit
1    12-08-2019   150       NULL      150
2    13-08-2019   100       50        50
3    17-08-2019   NULL      100       -100
4    18-08-2019   500       200       300

将来，我建议使用SHOW CREATE TABLE table_name发布一些表格详细信息，这将使我们能够为您提供更好的帮助。

您应该能够使用并集和一些分组来获得所需的信息：

SELECT
    Date,
    SUM(Income) as Income,
    SUM(Expense) as Expense,
    SUM(Income) - SUM(Expense) as Profit
FROM (
    SELECT
        due.date as Date,
        due.amount as Income,
        0 as Expense
    FROM due
    UNION ALL
    SELECT
        expenses.date as Date
        0 as Income,
        expenses.amount as Expense
    FROM expenses
)
GROUP BY Date
