获取 QuerySyntaxException：意外标记

Question

是的，我知道有几个帖子出现了这个错误，但是 none 个帖子帮助了我。我的 hql 查询出现此错误：

@SuppressWarnings("unchecked")
@Override
public List<StaffRequest> getStaffLeaveRequest(String userID, Date startDate, Date endDate) 
{
    Session currentSession = sessionFactory.getCurrentSession();        

    List<StaffRequest> results = 
    currentSession.createQuery("select new com.timesheet_Webservice.CustomEnity.StaffRequest(lr.leave_ID, lr.leave_Employee, concat(s.staff_First_Name, ' ', s.staff_Last_Name), "
            + "(lr.leave_Days*8.5), lr.leave_Comments, '1805', concat(pro.project_Pastel_Prefix, ' - ', pro.project_Description), lr.leave_Start, lr.leave_End, lr.leave_IsApproved, "
            + "(select lt.leaveType_Description from LeaveType lt where lt.leaveType_ID = lr.leave_Type)) "
            + "from Staff s, Leave lr, Project pro "
            + "where lr.leave_Employee, = s.staff_Code and pro.project_Code = 1805 and lr.leave_Approved = :userID, and lr.leave_IsApproved = 0 and s.staff_IsEmployee <> 0 "
            + "and lr.leave_Start between :startDate and :endDate "
            + "order by concat(s.staff_First_Name, ' ', s.staff_Last_Name)")
                                .setParameter("userID",userID).setParameter("startDate", startDate).setParameter("endDate", endDate).getResultList();   

    return results;
}

我不知道是什么问题。我尝试仔细地重新输入查询，我尝试遵循一些有效的类似查询的格式，但仍然一无所获。请帮助

更正后完整错误如下

Answer 1

"where lr.leave_Employee, = s.staff_Code",去掉逗号

where lr.leave_Employee = s.staff_Code

你在 "lr.leave_Approved = :userID,"

中有第二个逗号错误

lr.leave_Approved = :userID

请注意，在您的错误消息中有 unexpected token: , near line 1, column 665 因此，如果您将错误消息中打印的查询粘贴到文本编辑器中并删除换行符和多余的空格，您将在列（或位置，如果你喜欢的话）665.

题外话，但我可以建议您学习如何在查询中使用 JOIN，它会大大提高可读性
