You can grab a db connection directly from ActiveRecord::Base, but it's not as useful as extending AR::Base, because helpful methods like sanitize_sql are protected.

class ComplexQueries < ActiveRecord::Base
  def self.my_query
    # Notice how you can, and should, still sanitize params here. 
    self.connection.execute(sanitize_sql(["select * from foo limit ?", 10]))
  end
end

results = ComplexQueries.my_query
results.each_hash{|h| puts h.inspect}
