I'm running NHibernate 1.2 and getting the following error when trying to use CreateSQL:

Here is my code:
ISQLQuery query = NHibernateSession.CreateSQLQuery("SELECT * FROM [Plan]").AddEntity(typeof(Plan));
IList<Plan> x = query.List<Plan>();

Here is my mapping file:
<?xml version="1.0" encoding="utf-8" ?>
<hibernate-mapping xmlns="urn:nhibernate-mapping-2.2" assembly="UHG.MAPS.Core" namespace="UHG.MAPS.Core.Domain">
<class name="Plan" table="[Plan]">
<id name="ID" column="PlanID">
<generator class="identity" />
</id>

<property name="PBPNumber" column="[PBPNumber]" type="System.String" not-null="false" length="3"/>
</class>
</hibernate-mapping>

Here is the error stack:

If I use HQL and it works fine, just not working for SQL Query.

Any suggestions?
