```ruby
      def setup
        @conn = ActiveRecord::Base.connection
        @conn.exec_query('drop table if exists ex')
        @conn.exec_query(<<-eosql)
          CREATE TABLE `ex` (
            `id` int(11) auto_increment PRIMARY KEY,
            `number` integer,
            `data` varchar(255))
        eosql
      end
```
The setup actually creates it. I think I would probably want to remove ```@conn.exec_query('drop table if exists ex')``` from setup as well.
