I barely understood what you mean. There's no RowNumber() function in mysql, and partitioning has nothing to do with your request.

It's:

SELECT 
  t.*, 
  @cur:= IF(id=@id, @cur+1, 1) AS RowNumber, 
  @id := id 
FROM 
  t CROSS JOIN 
    (SELECT @id:=(SELECT MIN(id) FROM t), @cur:=0) AS init 
ORDER BY 
  t.id
