Question

我想保留字段名：Country，Cal_Year和Cal_Month。但是，如果我尝试运行代码，则代码将无法运行，如下面的示例代码所示。错误状态：＆＃39;国家/地区＆＃39;不是有效的字段名称。

LOAD [Country Code], 
         [ISO code], 
         Currency,
         ApplyMap('Currency_Map',Currency, 'Currency Unmapped') as Country, 
         Quotation, 
         year as Cal_Year, 
         trim(mid(period, 3,4)) as Cal_Month, 
         Balance, 
         Activity,
         (Balance/Quotation) as FX_Rate,
         Country & Cal_Year & Cal_Month as Key1   <-supposedly an erroneous statement

Answer 1

你缺少逗号吗？

(Balance/Quotation) as FX_Rate,  <-- missing comma here
Country & Cal_Year & Cal_Month as Key1

Answer 2

另外，这样做只能引用原始数据表，而不是结果。所以你需要

Country & Cal_Year & Cal_Month as Key1

成为

ApplyMap('Currency_Map',Currency, 'Currency Unmapped')
& year
& trim(mid(period, 3,4)) as Key

在添加逗号后也能正常工作

是＆＃34;加载＆＃34; Qlikview中的声明不允许在一个字段上进行多个顺序操作？
