What I am trying to do is take a return I find in a db table and use that name as a class name so that I can use activerecord.  I admit my understanding of ActiveRecord is extremely immature so perhaps I am using it wrong.

If you're getting the class name at run-time how would you write code 
that uses class after you've created it? I mean, you can't type the 
class name into your program now, you don't know what it is?

I suspect that what you really want to do is simply create a class and 
assign the result to a variable. Check out Class.new.

my_class = Class.new(ActiveRecord::Base)
my_inst = my_class.new
