在 Advance 编辑器中如何处理 power BI 中丢失的列/未找到 column1 错误?

In Advance editor how to handling missing columns / column1 not found error in power BI?

在 Power Bi 中,如果当前没有数据库查询数据,大多数时候我会收到错误 column1 not found。

如何处理请教我

为此我是这样处理的,提前编辑修改结果行

使用数据源

results = if List.IsEmpty(Record. Field(List.First (Source[results]),"data")) 
               then Record. Field (List.First (Source[results]),"alterData") 
          else Record. Field((List.First (Source [results]), "data")

用户电源双静态

let
    Source = Json.Document (Web.Contents ("https://xxxxxxxxxxxxx",
                   [Headers=[zzzzz="xxxxxx"]])),
                   body = Source [body],
                   content = body[content],
                   #"Converted to Table" = Table.FromList (content, Splitter.SplitByNothing(),
                     null,null, ExtraValues.Error}),
                  Tablel=Table. FromRecords ({
                                 [Columnl = ""]
                            }),
          result= if List.IsEmpty(content) then Tablel else #"Converted to Table"
in
    result
