NH 1.2. beta1
SQL Server 2000

IQuery q = m_Session.GetNamedQuery(QueryName);
NHibernate.Type.IType[] nTypes = q.ReturnTypes;

Note that <q> instance returned is a SQLQueryImpl, the named query i'm asking for is a SQL Query with <return-alias> and so on

It's a bug or i'm missing something?

Oh i forgot to write that the ReturnTypes threw this exception:

{"query must begin with SELECT or FROM: exec [exec EGroupEventProcess_ByGroup :GroupId]"}

(note that exec EGroupEventProcess_ByGroup is a SP call)
