Qlikview 中的 "Load" 语句是否不允许对一个字段进行多个顺序操作？

Question

我想保留字段名：国家/地区、Cal_Year 和 Cal_Month。但是，如果我尝试运行ning 它，代码不会运行，如以下示例代码中所写。错误状态：'Country' 不是有效的字段名。

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

您缺少逗号？

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

Answer 2

同样这样做只能参考原始数据table，不能参考结果。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

它在添加逗号后也能正常工作

Does the "Load" statement in Qlikview not permit multiple sequential operations on a field?
