Answer 1

Вы не можете назвать таблицу order, так как это зарезервированное слово в синтаксисе SQL: http://dev.mysql.com/doc/refman/5.5/en/reserved-words.html. Однако вы можете изменить свое имя таблицы на заказы с использованием сопоставлений:

class Order { 
    static mapping = { 
     table "orders" 
    } 
}
