【问题描述】：

我想让一定比例的白人分开，而其余种族将是目前正在从事的项目中的有色人种。请帮助我如何使用 CASE 或 IF 语句编写 DAX。

我使用了 SWITCH，它给出了错误

Race_Ethnicity = 
SWITCH(TRUE(),
    'Contact'[race_and_ethnicity] = "White or European", "White or European",
    'Contact'[race_and_ethnicity] = "Black or African", "Black or African",
    'Contact'[race_and_ethnicity] = "Hispanic or Latinx", "Hispanic or Latinx",
    'Contact'[race_and_ethnicity] = "Prefer not to answer", "Prefer not to answer",
    'Contact'[race_and_ethnicity] = "South Asian", "South Asian",
    'Contact'[race_and_ethnicity] = "East Asian", "East Asian",
    'Contact'[race_and_ethnicity] = "Middle Eastern", "Middle Eastern",
    'Contact'[race_and_ethnicity] = "Southeast Asian", "Southeast Asian",
    'Contact'[race_and_ethnicity] = "Pacific Islander", "Pacific Islander",
    'Contact'[race_and_ethnicity] = "Indigenous","Indigenous",
    'Contact'[race_and_ethnicity] = "Other, please specify:", "Other, please specify:",
    'Contact'[race_and_ethnicity] = ".*(;).*", "Mixed Race or Ethnicity",
)

我希望有白人或欧洲人的百分比以及有色人种的百分比

【解决方案1】：

这里有两个措施。一个是白人/欧洲人的百分比：

WOE % = 
VAR _count = 
    CALCULATE ( 
        COUNTROWS ( 'Contact' ) , 
        'Contact'[race_and_ethnicity] = "White or European"
    )
RETURN
    DIVIDE ( 
        _count , 
        COUNTROWS ( 'Contact' )
    )

一个相反：

POC % = 
VAR _count = 
    CALCULATE ( 
        COUNTROWS ( 'Contact' ) , 
        'Contact'[race_and_ethnicity] <> "White or European"
    )
RETURN
    DIVIDE ( 
        _count , 
        COUNTROWS ( 'Contact' )
    )
