Migration - wrong SQL statement is created


I am doing my first steps with RoR and I have the following problem:

I execute my migration file with the following content on a MySQL-database via Rake:

<code> class CreateUsers < ActiveRecord::Migration def self.up create_table :users do |t| t.integer :id

You don't need the line for id, rails will add it automatically


Thank you very much for your quick answers!
