Are all the accessors created automatically in non-Rails application

I wonder if all the accessors are created automatically in non-Rails
application? By requiring ''active_record'' and
''rubygems'' didn''t solve
my problem. I just created a Ruby file with 2 classes inside:
@@@
require ''rubygems''
require ''active_record''

ActiveRecord::Base.establish_connection(
  :adapter => ''oracle_enhanced'',
  :database => ''db_bname,
  :username => ''username,
  :password => ''pwd''
)

class Supplier < ActiveRecord::Base
  set_table_name :lcssupplier
  set_primary_key :ida2a2
end

class RunUpdate
  def initialize(env = "dev")
   @env = env
    case @env
    when ''dev''
      @name = ''att1''
    else
      raise "Unknown environment: #{env}"
    end
    update_dpp_suplliers
  end

private
  def update_dpp_suplliers
    dpp_supplier = Supplier.where(:num2=>56180).first
    puts "Reading supplier name before update:
#{dpp_supplier.read_attribute(@name)}"
    dpp_supplier.send("#{@name}=", "TOTO")
    dpp_supplier.save!
    puts "DPP supplier name AFTER update:
#{dpp_supplier.read_attribute(@name)}"
  end
end

RunUpdate.new(''dev'')
@@@

It works without problem on another database (MySQL) but raises an
error on Oracle DB. The only difference is that when running on MySQL
DB, I didn''t have to use ''set_table_name'' and
''set_primary_key''
because the table was created according the RoR convention. It''s not
the case for Oracle table.
Here is the error I get:

I don''t the behaviour of a rails app is significantly different
compared to a standalone ruby script that happens to use active record.
By the looks of it rails is barfing because it''s trying to define a
method called blob$entrysetadhocacl? which isn''t a legal method name.
Do you have a column of that name?
