升级到 Nhibernate 3 后出现奇怪的问题

Question

你好 我有一个映射为采用日期字段的查询。 升级到 NHibernate 3 后出现以下错误：

could not execute query
[ select a.agency_num, cd.comp_name, sd.sib_number, sd.sib_type_label,
ad.add_line1, ad.add_line2, ad.add_line3, ad.add_line4, ad.post_code,
ad.country_label
from
agency a, company_details cd, sib_dets sd, address ad
where
a.contact_ser = cd.contact_ser
and a.contact_ser = sd.contact_ser
and a.contact_ser = ad.contact_ser
and a.current_ser = 10
and a.start_date <= ?
and (a.end_date is null or a.end_date >= ?)
and cd.current_ser = 10
and cd.start_date <= ?
and (cd.end_date is null or cd.end_date >= ?)
and sd.current_ser = 10
and sd.start_date <= ?
and (sd.end_date is null or sd.end_date >= ?)
and ad.current_ser = 10
and ad.start_date <= ?
and (ad.end_date is null or ad.end_date >= ?) ]
  Name:dateValid - Value:18/02/2011 00:00:00
[SQL: select a.agency_num, cd.comp_name, sd.sib_number,
sd.sib_type_label,
ad.add_line1, ad.add_line2, ad.add_line3, ad.add_line4, ad.post_code,
ad.country_label
from
agency a, company_details cd, sib_dets sd, address ad
where
a.contact_ser = cd.contact_ser
and a.contact_ser = sd.contact_ser
and a.contact_ser = ad.contact_ser
and a.current_ser = 10
and a.start_date <= ?
and (a.end_date is null or a.end_date >= ?)
and cd.current_ser = 10
and cd.start_date <= ?
and (cd.end_date is null or cd.end_date >= ?)
and sd.current_ser = 10
and sd.start_date <= ?
and (sd.end_date is null or sd.end_date >= ?)
and ad.current_ser = 10
and ad.start_date <= ?
and (ad.end_date is null or ad.end_date >= ?)]

内部异常是： {“参数名称为‘p0’的 IfxParameter 已包含在 this IfxParameterCollection."}

有人知道这是为什么吗？它在以前的版本下工作正常 NHibernate

这是我的 NHibernate 代码：

using (ISession session = NHibernateHelper.OpenSession(FACTORY_NAME))
    {
    IQuery query = session.GetNamedQuery("GetAllAgents");
    query.SetDateTime("dateValid", dateValid.Date);
    agents = query.List<AgencySearchData>();
    }

这是我的映射文件：

    <hibernate-mapping xmlns="urn:nhibernate-mapping-2.2"
               assembly="SeiDomain"

      <class name="AgencySearchData">
        <id name="AgencyNumber" column="agency_num"/>
        <property name="Name" column="comp_name" />
        <property name="SibNumber" column="sib_number" />

    ad.country_label
    from
    agency a, company_details cd, sib_dets sd, address ad

    a.contact_ser = cd.contact_ser

我相信这可能与 NH-2529 有关。

看看该修复是否适合您，然后投票。
