首先需要将数据添加到数据模型中 添加后的Power Pivot窗口 退出Power Pivot窗口后,点击“新建度量值” 度量值名称:不重复省份数量 公式中输入 =DISTINCTCOUNT('订单表'[省份]) DISTINCT函数可以去除重复值 DISTINCTCOUNT函数是统计去除重复值后的数量 这些都是Power Pivot模型中的DAX函数。 建立好度量值后...
例如,可以使用Power Query或DAX函数先对数据进行筛选和聚合,然后再应用Distinctcount函数。 -对于性能要求较高的情况,可以考虑使用其他聚合函数替代Distinctcount函数,例如Count函数或Sum函数。 综上所述,Distinctcount函数在Power BI中是一个非常有用的工具,可用于计算给定列中的唯一值数量。无论是作为聚合函数还是计算...
