Thank goodness for that! But I wasn't able to find "drop column" and resorted to http://www.oracle.com/technology/pub/articles/kern-rails-migrations.html to find this list: 13 remove_column :albums, :year 14 rename_column :albums, :year_int, :year 15 change_column :albums, :year, :integer, :limit => 4, :null => false which gave me the answer I really wanted: #15 Bottom line: you're a great resource. You pointed me in the right directions and I got to Nirvana!
