Я использую курсор в SQL Server 2005, правильно это или нет?

Question

На странице aspx у меня есть два раскрывающихся списка, который представляет собой раскрывающийся список фестиваля и раскрывающийся список года соответственно, когда пользователь выбирает одно значение в фестивале, например Рождество и раскрывающийся список года, предположим, что 2011 год, так что все детали фильма должны выглядеть в aspВот почему я использую курсор в SQL Server 2005, но с некоторым условием

1. пользователь может выбрать значение из выпадающего списка года. «Все» фестиваль должен быть индивидуальным.
2. год должен бытьИндивидуальный и случайный Индивидуальный
3. год должен быть Индивидуальным и случайный Индивидуальный

3-е состояние Я закончил, но 1-е и 2-е условия как я могу не получить ...?
