Power Query / Power BI - 用另一列中的值替换空值

Posted 2023-04-14

【中文标题】Power Query / Power BI - 用另一列中的值替换空值

【英文标题】：Power Query / Power BI - replacing null values with value from another column

【发布时间】：2020-04-06 09:36:14

【问题描述】：

尽管“未检测到语法错误”，但我遇到了以下错误，我遇到了一个错误：

Expression.Error：无法识别名称“each_”。确保拼写正确。

这里是代码行，包括最后一行，由于某种原因显然是问题所在。 （我正在尝试将“日期”列中的空值替换为“PS 源文件名 - Copy.1”列中的值）

非常感谢您的帮助。

#"Split Column by Delimiter1" = Table.SplitColumn(#"Reordered Columns", "APS Source File Name - Copy", Splitter.SplitTextByEachDelimiter(" ", QuoteStyle.Csv, false), "APS Source File Name - Copy.1", "APS Source File Name - Copy.2"),
#"Changed Type3" = Table.TransformColumnTypes(#"Split Column by Delimiter1","APS Source File Name - Copy.1", type date, "APS Source File Name - Copy.2", type text),
#"Reordered Columns1" = Table.ReorderColumns(#"Changed Type3","APS Source File Name", "APS Source File Name - Copy.2", "APS Source File Name - Copy.1", "Date"),
#"Replaced Value" = Table.ReplaceValue(#"Reordered Columns1",null,each_("APS Source File Name - Copy.1",Replacer.ReplaceValue,"Date"))

in
    #"Replaced Value"

【参考方案1】：

试试#"Replaced Value" = Table.ReplaceValue(#"Reordered Columns1",null, each [#"APS Source File Name - Copy.1"],Replacer.ReplaceValue,"Date")
