Заменил везде в тексте SQL на Sql и ошибок с этим больше нет, но на другом застрял.
Решил все переделать на работу с Access.

Выдает ошибку после нажатия на кнопку (процедура
public void AddAuthor_Click(Object sender, EventArgs E))
"ОШИБКА: Невозможно добавить запись,пожалуйста, убедитесь, что поля правильно заполнены";
Подскажите в чем моя ошибка.
