 Well, in this case you can use anonymous struct

   row_class = Struct.new(nil, *res.names)

 ruby will create a new class for each call, or if you want named struct,
 something like this (not tested)

   @structname = 'SQLRow00'

   def find_struct(*names)
      ObjectSpace.each_object(Class) do |x|
         if x < Struct && /SQLRow\d\d\Z/ =~ x.to_s && x.members == names
            return x
         end
      end
      Struct.new(@structname.succ!, *names)
   end

   def create_struct(res)
      row_class = find_struct(*res.names)
      # ...
   end
