我在NHibernate中有一个映射,如下所示:

 <?xml version="1.0" encoding="utf-8"?>
    <hibernate-mapping namespace="News.BusinessEntity" assembly="News.BusinessEntity" xmlns="urn:nhibernate-mapping-2.2">

    <class name="News" table="News">
       <property name="NewsId" type="Int64" column="NewsId"   />
       <property name="NewsTitle" type="String" column="NewsTitle"  />
    </class>

    <sql-query name="Sp_News">
           <return class="News" />
           exec Sp_News
    </sql-query>

</hibernate-mapping>

当我打电话时,session.GetNamedQuery("Sp_News")我收到以下错误:

Named query not known: Sp_News.

任何帮助将非常感激.
