try(Session session = sessionFactory.openSession()) {
        session.beginTransaction();
        String hql = "update EmployeeTask set employee = 1 where employee is null";
        session.createQuery(hql, EmployeeTask.class).executeUpdate();
        session.getTransaction().commit();
    }

抛出以下内容
原因：org.hibernate.query.IllegalQueryOperationException：为非SELECT查询指定的结果类型[update EmployeeTask set employee = 1，其中employee为null]
我希望“employee”列中当前为空的所有值都将具有值1
