需要来自criteriaQuery-->帮助的nhibernate NamedQuery

我试图将工作条件查询转换为命名查询，但语法不正确。hql版本显然需要指定类型和id参数

查询是在一个类上进行的，该类还映射了下面的任何

谁能帮我把语法弄好吗

干杯， 贝里尔

工作条件查询 任何有效的映射都可以！ 命名查询到目前为止不起作用 我认为这是hql语法，但错误消息说缺少参数

....
          select a 
          from Allocation a 
          where a.Resource = :resource 
            and a.TimeRange.StartTime between :periodStart and :periodEnd
          order by a.TimeRange.StartTime
....

        return _session.GetNamedQuery("FetchByResourceForDateRange")
            .SetEntity("resource", resource)
            .SetDateTime("periodStart", searchRange.Start)
            .SetDateTime("periodEnd", searchRange.End)
            .List<Allocation>();

使现代化 这个组合执行，但给出了错误的答案。还不知道它离我需要的东西是近还是远

          select a 
          from Allocation a 
          where a.Resource.class = :class and a.Resource.id = :id 
            and a.TimeRange.StartTime between :periodStart and :periodEnd
          order by a.TimeRange.StartTime

        return _session.GetNamedQuery("FetchByResourceForDateRange")
            .SetString("class", typeof(Resource).FullName)
            .SetInt32("id", resource.Id)
            .SetDateTime("periodStart", searchRange.Start)
            .SetDateTime("periodEnd", searchRange.End)
            .List<Allocation>();

好的，根据NHib开发负责人Fabio Maulo的说法：

您必须使用元数据值，而不是typeofentity.FullName

因此，在我的案例中，以下是我最后一次使用hql：

return _session.GetNamedQuery("FetchByResourceForDateRange")
        .SetString("class", "EMPLOYEE")
        .SetInt32("id", resource.Id)
        .SetDateTime("periodStart", searchRange.Start)
        .SetDateTime("periodEnd", searchRange.End)
        .List<Allocation>();

比我希望的要难看一点，但我会接受：-

嗯,， 贝里尔

          select a 
          from Allocation a 
          where a.Resource.class = :class and a.Resource.id = :id 
            and a.TimeRange.StartTime between :periodStart and :periodEnd
          order by a.TimeRange.StartTime

        return _session.GetNamedQuery("FetchByResourceForDateRange")
            .SetString("class", typeof(Resource).FullName)
            .SetInt32("id", resource.Id)
            .SetDateTime("periodStart", searchRange.Start)
            .SetDateTime("periodEnd", searchRange.End)
            .List<Allocation>();

return _session.GetNamedQuery("FetchByResourceForDateRange")
        .SetString("class", "EMPLOYEE")
        .SetInt32("id", resource.Id)
        .SetDateTime("periodStart", searchRange.Start)
        .SetDateTime("periodEnd", searchRange.End)
        .List<Allocation>();
