nhibernate named queries , name not found

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?

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.

Also, make sure that your mapping file Build Action is set as "Embedded Resource", or you'll get the same error even if the mapping file itself is correct.

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
