Check some column have some values
Hello kongyuancn
check out this dynamic solution. Use variable ColStartWith to identify all columns that start with that word. Use variable ContentSearchFor to define a list of words to check for
let Source = Table.FromRows(Json.Document(Binary.Decompress(Binary.FromText("i45WSlTSUUoC4mQ4jtWBiIIwjAKJJUH4yVCxRLBgMkQwCSqYpBQbCwA=", BinaryEncoding.Base64), Compression.Deflate)), let _t = ((type nullable text) meta [Serialized.Text = true]) in type table [No_1 = _t, Yes_1 = _t, Yes_2 = _t, No_3 = _t, Yes_4 = _t]), #"Changed Type" = Table.TransformColumnTypes(Source,{{"No_1", type text}, {"Yes_1", type text}, {"Yes_2", type text}, {"No_3", type text}, {"Yes_4", type text}}), ColStartWIth = "Yes", ContentSearchFor = {"b", "c"}, GetYesColumns = List.Select(Table.ColumnNames(#"Changed Type"), each Text.StartsWith(_, ColStartWIth)), CheckIfColHasContent = Table.AddColumn ( #"Changed Type", "CheckYesColumnsForContent", (row)=> let GetTable = Record.ToTable(row), FilterForColumns = Table.SelectRows(GetTable, (rowsel)=> List.Contains(GetYesColumns, rowsel[Name])), FilterForContent = Table.SelectRows(FilterForColumns, (rowsel)=> List.Contains(ContentSearchFor, rowsel[Value])) in if Table.IsEmpty(FilterForContent) then false else true ) in CheckIfColHasContentCopy paste this code to the advanced editor in a new blank query to see how the solution works.

Hi kongyuancn
Try this code. You can also download this PBIX file with the same example code
let
Source = Table.FromRows(Json.Document(Binary.Decompress(Binary.FromText("i45WSlTSUUoC4mQ4jtWBiIIwjAKJJUH4yVCxRLBgMkQwCSqYpBQbCwA=", BinaryEncoding.Base64), Compression.Deflate)), let _t = ((type nullable text) meta [Serialized.Text = true]) in type table [No_1 = _t, Yes_1 = _t, Yes_2 = _t, No_3 = _t, Yes_4 = _t]),
#"Changed Type" = Table.TransformColumnTypes(Source,{{"No_1", type text}, {"Yes_1", type text}, {"Yes_2", type text}, {"No_3", type text}, {"Yes_4", type text}}),
#"Added Custom" = Table.AddColumn(#"Changed Type", "Yes_Col_Have_B_or_C", each if ([Yes_1] ="b" or [Yes_2] = "b" or [Yes_4] = "b") or ([Yes_1] ="c" or [Yes_2] = "c" or [Yes_4] = "c") then true else false)
in
#"Added Custom"

Thank you Phil for your answer. But I still have a question:
There maybe a lot of "Yes" columns, how can I use a function (Ex: List.FindText(Table.ColumnNames(#"Table"), "Yes")) instead of specifying those columns one by one?
Further more, I have a matching list (not only "b" and "c"). Is it possible that using the list in the formular instead of specifying them one by one?
Hi kongyuancn
You can use this code - here's the PBIX file
It searches for any column names containing "Yes"and then just uses those to create the True/False column
let Source = Table.FromRows(Json.Document(Binary.Decompress(Binary.FromText("i45WSlTSUUoC4mQ4jtWBiIIwjAKJJUH4yVCxRLBgMkQwCSqYpBQbCwA=", BinaryEncoding.Base64), Compression.Deflate)), let _t = ((type nullable text) meta [Serialized.Text = true]) in type table [No_1 = _t, Yes_1 = _t, Yes_2 = _t, No_3 = _t, Yes_4 = _t]), Tab = Table.SelectColumns(Source, List.FindText(Table.ColumnNames(Source),"Yes")), TF = List.Transform(Table.ToList(Tab), each Text.Contains(_,"b") or Text.Contains(_,"c")), Columns = List.Combine({Table.ToColumns(Source),{TF}}), #"Converted to Table" = Table.FromColumns(Columns,List.Combine({Table.ColumnNames(Source),{"Yes_Col_Have_B_or_C"}})) in #"Converted to Table"Phil
