If you pass a name as the first parameter to Struct.new, those 
names have to be unique. You can solve your problem by passing 
nil as the first argument to Struct.new:

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

I suppose you don't refer to the name "SQLRow" anywhere else in 
your program, do you?
