Столбец с ошибкой запроса к базе данных не найден только в запланированном задании

У меня есть задача сохранять данные в базе данных каждые 10 секунд или около того.Я использую Spring Boot с архитектурой MVC.Когда я пытаюсь получить данные из базы данных, выдается сообщение об ошибке, в котором говорится, что столбец не найден, хотя столбец существует.Если я использую запрос, он работает как надо.Но когда я запускаю его из запланированной задачи, он выдает ошибку.

Как видите, столбец last_name создан и существует.Я не знаю, почему он выдает ошибку из запланированного задания.Нужна помощь.Заранее спасибо.

Ваш запрос не завершен.

Вы хотите вернуть объект Student, но вы просто выбираете student_id. Вы должны выбрать все столбцы.

Это должно работать: 

 @Query(value="SELECT student_table.* FROM student student_table WHERE NOT EXISTS (SELECT relationship_table.student_id FROM relationship_table relationship_table WHERE student_table.student_id = relationship_table.student_id)", nativeQuery=true)
 List<Student> getAllStudentsWithoutStudentAccount();
...
