oracle adapter and rails migrations

The Oracle adapter for active record has a bug that does not allow to create a dump of the schema using rake. The following code is from http://dev.rubyonrails.org/ticket/10415 and corrects this problem.

require 'active_record/connection_adapters/oracle_adapter'
module ActiveRecord
  module ConnectionAdapters
   class OracleAdapter
     # Returns an array of arrays containing the field values.
     # Order is the same as that returned by #columns.
     def select_rows(sql, name = nil)
       result = select(sql, name)
       result.map{ |v| v.values}
     end
   end
 end
end
