Get row number with Google spreadsheet query language

Question

I\'d like to get the row number of the data I need with query language, i.g: select A,ROW_NUMBER() where (B=1).

But it seems the query language doesn\'t provide func

Answer 1

You can add a column with arrayformula(row(...)) to the queried range, and include it in results. Example:

=query({A2:B, arrayformula(row(A2:B))}, "select Col1, Col3 where Col2 = 1")

Here Col1 = A, Col2 = B, Col3 = added column with the row number. Since the array to be queried is constructed within the formula, its columns are referred to as Col1, Col2, and so on.
