Escape column name in query (to avoid conflict with reserved words)

Question

I have a Google Sheets and want to query in a column called BY. This is failing:

=query(Data!A:GC, \"select BY where BG = \'completed\'\")
         


        

Answer 1

so to use the column BY as an identifier you must use backquotes around it...

`BY`
