title: How to transform query?
body: <p>i have an sql query that has one unnamed column as a list of strings.</p>
  
  <p>my hbm is declared as follows:</p>
  
  <pre><code>&lt;hibernate-mapping xmlns="urn:nhibernate-mapping-2.2" assembly="Services.Data"  namespace="Services.Data" &gt;
    &lt;sql-query name="GetDiagramSubscriptions"&gt;
      exec Diagram_Subscriptions:contactId
    &lt;/sql-query&gt;
  &lt;/hibernate-mapping&gt;
  </code></pre>
  
  <p>my repository method:</p>
  
  <pre><code>IQuery query = Session.GetNamedQuery("GetDiagramSubscriptions")
              .SetInt32("contactId", contactId)
              .SetResultTransformer(Transformers.AliasToBean&lt;string&gt;());
  
  return query.List&lt;string&gt;();
  </code></pre>
  
  <p>this doesn't work because type string doesn't have a setter.</p>
  
  <p>i don't want to declare a mapping class just for this one column.  is there a way to transform this to a Tuple or something?</p>
