powerbi - 如何在 power bi 高级编辑器中将今天的日期作为动态输入日期传递？

Question

我正在尝试在高级查询编辑器中传递截至今天日期的日期值

let 
    Source = GoogleBigQuery.Database(null),
    #"apple-5a221" = Source{[Name="apple-5a221"]}[Data],
    analytics_187358390_Schema = #"apple-5a221"{[Name="analytics_187358390",Kind="Schema"]}[Data],
    events_intraday_20200129_Table = analytics_187358390_Schema{[Name="events_intraday_20200129",Kind="Table"]}[Data]
in
    events_intraday_20200129_Table

Answer 1

要通过今天的动态日期：

花了一个小时后，我找到了解决方案[Name="events_intraday_"&datetime&"“并宣布datetime = DateTime.ToText(DateTime.LocalNow(), "yyyyMMdd")

let 
    datetime = DateTime.ToText(DateTime.LocalNow(), "yyyyMMdd"),
    Source = GoogleBigQuery.Database(null),
    #"apple-5a221" = Source{[Name="apple-5a221"]}[Data],
    analytics_187358390_Schema = #"apple-5a221"{[Name="analytics_187358390",Kind="Schema"]}[Data],
    events_intraday_20200129_Table = analytics_187358390_Schema{[Name="events_intraday_"&datetime&"",Kind="Table"]}[Data]
in
    events_intraday_20200129_Table

要通过昨天的动态日期：

datetime = Date.ToText(Date.AddDays(Date.From(DateTime.FixedLocalNow()),-1), "yyyyMMdd")

let
    datetime =  Date.ToText(Date.AddDays(Date.From(DateTime.FixedLocalNow()),-1), "yyyyMMdd"),
    Source = GoogleBigQuery.Database(null),
    #"prutopia-5a221" = Source{[Name="apple-5a221"]}[Data],
    analytics_187358390_Schema = #"apple-5a221"{[Name="analytics_187358390",Kind="Schema"]}[Data],
    events_datetime_Table = analytics_187358390_Schema{[Name="events_"&datetime&"",Kind="Table"]}[Data]
in
    events_datetime_Table
