Question

我在Qlik Sense中有以下格式的数据：

Date       Customer Flag
2016-10-01   A       1
2016-10-01   B       0
2016-10-02   A       1
2016-10-02   C       1
2016-10-03   A       1
2016-10-03   B       1
2016-10-03   C       1
2016-10-05   C       1
2016-10-10   A       0
2016-10-10   B       1
2016-10-11   C       0

我想以下列格式在Qlik Sense的表格中显示这些数据：

#Week     Count Distinct Customer Where Flag is 1
39           2
40           3
41           3

背后的逻辑：我需要周计数的DISTINCT客户，其中该周的Flag = 1，包括前一周。因此，此处第40周将显示第39周和第40周的不同计数。同样，第41周将显示第40周和第41周的不同计数。依此类推。

如果有人能为上述建议使用Qlik Sense表达式，我将不胜感激？

Answer 1

在我看来，这应该在脚本级别解决，而不是试图使表达式/ GUI复杂化（如果可能的话）

下面的脚本会创建另外的表Dates，其中包含Date - ＆gt; Week链接。 Week可以用作正常维度。

RawData:
Load * Inline [
    Date      , Customer, Flag
    2016-10-01, A       , 1
    2016-10-01, B       , 0
    2016-10-02, A       , 1
    2016-10-02, C       , 1
    2016-10-03, A       , 1
    2016-10-03, B       , 1
    2016-10-03, C       , 1
    2016-10-05, C       , 1
    2016-10-10, A       , 0
    2016-10-10, B       , 1
    2016-10-11, C       , 0
];

// Generate week number from the existing dates
Dates_Temp:
Load 
    Date, 
    Week(Date)  as Week
Resident
    RawData
;   

Concatenate

// Generate previous week number from the existing dates
Load 
    Date, 
    Week(Date + 7)  as Week // Generate the previous week number
Resident
    RawData
;   

// The following code will remove week 42
// If week 38 need to be visible just ignore/delete 
// the script below --->

// Find the max week from the generated weeks
MaxWeek:
Load
    max(Week) as maxWeek
Resident
    Dates_Temp
;   

// Load the min week in vMaxnWeek variable
let vMaxWeek = peek('maxWeek');

// This table is not needed anymore
Drop Table MaxWeek;

NoConcatenate

// The new Dates table will contain all weeks apart from week 42
Dates:
Load
    *
Resident
    Dates_Temp
Where
    Week <> $(vMaxWeek)
;

Drop Table Dates_Temp;

let vMaxWeek = null();

执行脚本后，数据结构如下所示：

Dates表将包含以下数据：

正如您所看到的那样，每个日期都有两周的数字。（只有第39周是单一记录，因为从数据中删除了第38周。不确定是否需要）

所以在此之后表达非常简单：

= count( {< Flag = {1} >} distinct Customer)

结果是：

P.S。屏幕截图来自QlikView，但同样的加载代码和表达式也可以在QS中使用

作为Stefan回答的替代方案，Qlik Sense在日期方面有一些很棒的功能。以下内容可以插入到您的脚本中，并在选择器屏幕上生成可以使用的其他字段。

DERIVE FIELDS FROM FIELDS [CurrencyDate]
USING [Calendar] ;

这将使用与Stefan相同的表达式。

= count( {< Flag = {1} >} distinct Customer)

这样做的好处

字段隐藏在下拉列表中，因此不要混乱字段选择
可以在同一堆栈中处理多个日期，只需使用derive from fields
