Почему не проходит HQL запрос?

Подскажите, пожалуйста, что здесь не так? Хочу извлечь salary,subject, FirstName данные три поля, при том, что salary>500, но получаю Exception вида

Exception in thread "main" java.lang.IllegalArgumentException: org.hibernate.hql.internal.ast.QuerySyntaxException: unexpected token: by near line 1, column 76 [select e.salary,e.FirstName,m.subject 

Не могли бы вы объяснить что я делаю не так?

List list1;
Query query1 = session.createQuery("select e.salary,e.FirstName,m.subject from Employee e,Meeting m where e.salary>500");
list1 = query1.list();
log.info("=====");
list1.stream().forEach(emplSalary -> log.info(emplSalary.toString()));
