Help! Error occurs while creating db schema for MySQL 5.0 using migration.

Hi all,

I'm creating the db schema for MySQL 5.0 using migration but run into error. My migration file is as follows:

class CreateCustomers < ActiveRecord::Migration   def self.up     create_table :customers do |t|       t.column :id, :integer, :null => false       t.column :name, :string     end   end

  def self.down     drop_table :customers   end end

And the error information is:

== CreateCustomers: migrating

class CreateCustomers < ActiveRecord::Migration   def self.up     create_table :customers do |t|       t.column :id, :integer, :null => false       t.column :name, :string     end   end

id column generates automatically :wink:
