使用无状态会话时，IQuery的Enumerable上的NotSupportedException [英] NotSupportedException on IQuery's Enumerable when using statelesssession

问题描述

当尝试通过无状态会话在命名查询上使用Enumerable方法时，如以下示例所示:

when trying to use the Enumerable method on a named query, with a Stateless session, as shown in the example at:

http://www.nhforge.org/doc/nh/zh/#batch-statelesssession

我看到一个NotSupportedException.堆栈跟踪如下:

i am seeing a NotSupportedException. the stack trace is as below:

System.NotSupportedException: Specified method is not supported.
at NHibernate.Impl.StatelessSessionImpl.Enumerable(String query, QueryParameters parameters)
at NHibernate.Impl.QueryImpl.Enumerable()

下面是我的代码段:

IStatelessSession statelessSession = sessionFactory.OpenStatelessSession();
var fileLines = statelessSession.GetNamedQuery("GetLinesByFileId")
.SetInt32("FileIdInput", fileId).Enumerable<FileLineEntity>();

命名查询GetLinesByFileId在hbm中定义如下:

the named query, GetLinesByFileId is defined in the hbm as below:

<query name="GetLinesByFileId" cacheable="false" read-only="true">
    <![CDATA[
        from FileLineEntity lineItem where lineItem.FileId=:FileIdInput 
      ]]>
  </query>

关于我可能在这里缺少的任何建议吗?

any suggestions on what i maybe missing here?

推荐答案

文档错误.另外，通过查看它，您可以知道它是从Hibernate(Java)复制而来的.

The doc is wrong. Also, by looking at it you can tell it's copied from Hibernate (Java).

请改用List方法.
