    Hi qasimawan ,
    sorry, yes, the code has to be adjusted:
    if List.Contains(#"query1"[Concat], [Concat]) then "true" else "false"

Hi qasimawan ,

if my understanding is correct, you want to check if a certain value in each row of a table (query2) is contained anywhere in the whole column of table from query1.
If so, you'd add a column in query2 like so:

if List.Contains( Table.SelectColumns(#"query1","Concat"), [Concat]) then "true" else "false"
