查询单个日期，按条件计算值

Question

我想要一个只显示单个日期的查询（因此不会出现单个日期 twice/multiple），计算给定日期的记录数，并进一步计算另一个字段满足其他条件的记录数：

Date    | total amount | Field2 = "Aaa" | Field2 = "Bbb" | Filed2 = ....
10.7.18 | 32           | 2              | 3              | ...
11.7.18 | 20           | 5              | 2              | ...

我的方法是将其属性设置为 "unique values" 到 "yes" 的查询，然后我两次添加日期字段，首先将其功能设置为 "group by"，第二个函数设置为"count"；这只给我个人日期和设定日期的记录数。到目前为止一切顺利。

现在我添加"Field2"，将其函数设置为"count"，并将条件添加到“=Value("Aaa")”。这将显示一个空的记录列表。

试试这个：

Select
    [Date],
    Sum(Amount) As TotalAmount,
    Sum(Abs(Field2 = "Aaa")) As CountA,
    Sum(Abs(Field2 = "Bbb")) As CountB,
    Sum(Abs(Field2 = "Ccc")) As CountC
From
    YourTable
Group By
    [Date]

如果您只需要总计 count，请使用：

Select
    [Date],
    Count(*) As TotalCount,
    Sum(Abs(Field2 = "Aaa")) As CountA,
    Sum(Abs(Field2 = "Bbb")) As CountB,
    Sum(Abs(Field2 = "Ccc")) As CountC
From
    YourTable
Group By
    [Date]
