nhibernate命名查询，找不到名称

Question

I'm coming from a Java side of using Hibernate and I just haven't found the proper place to put the named query in NHibernate .

Using Visual Studio 2008 , C# 2008

I have a query

<query name="SchwabAccountList">
  from DB_Accounts a
  where a.AdminOffCode = 'SWB'
</query>

and I want to put it in the .hbm.xml for the Account table ( DB_Accounts )

I put it at the end of the file but within the <class> tag

    <query name="AccountList">
      from DB_Accounts a
      where a.AdminOffCode = 'SWB'
    </query>
  </class>
</hibernate-mapping> 

The code I am using, I have tried several different ways but get

Named query not known: AccountList

or whatever other name I tried to use ( assembly.dir.dir.class.queryname ) that sort of thing.

The access code looks like.

              ISessionFactory factory = cfg.BuildSessionFactory();
              ISession session = factory.OpenSession();

              IList<DB_Accounts> accountList = 
                  (IList<DB_Accounts>)(session.GetNamedQuery("AccountList").List());

              foreach (BDM_Controller.Source.ORM.DB_Accounts acctRec in accountList)
              {
                         ...

What am I missing?

Answer 1

I moved the query outside the tag and got it to recognize the query. I had it at the top of the mapping file earlier and it complained about the following tag. It might have been a problem with the single quote. I added the CDATA wrapper to protect against those issues. So a combination of the two change probably solved the problem.

I now have:

  </class>
  <query name="AccountList" cacheable="true" read-only="true">
    <![CDATA[
      from DB_Accounts a
      where a.AdminOffCode = 'SWB'
      ]]>
  </query>
</hibernate-mapping> 

and this works

另外，请确保将映射文件的“构建操作”设置为“嵌入资源”，否则即使映射文件本身正确，也会出现相同的错误。

Also make sure that the hbm file is added with extension .hbm.xml rather than just .xml. This also will result in the same error.
