Java 由表名引起的SQLGrammarException错误

我有一个正在执行的hql查询，但收到一个错误，我并不真正了解其原因。我做了各种测试，错误似乎不是由我的离开表名引起的。我甚至不能做一个简单的“离开”查询，我会收到同样的错误。但是，如果我将workbench数据库中的表重命名为其他任何名称，甚至只是“离开”，那么查询执行时不会出错。我不明白这是为什么。是在mysql工作台中留下某种保留字还是什么

这是我的密码

public List<StaffRequest> getStaffLeaveRequest() {
    Session currentSession = entityManagerFactory.unwrap(SessionFactory.class).openSession();

    List<StaffRequest> results = currentSession.createQuery(
            "select from Leave").getResultList();

    return results;
}

这是堆栈跟踪
