在NHibernate中查询未映射的列

string sql = "SELECT column1, column2 FROM table_name";
ISQLQuery query = session.CreateSQLQuery(sql);
query.AddScalar("column1", NHibernateUtil.String);
query.AddScalar("column2", NHibernateUtil.Int32);
query.SetResultTransformer(Transformers.AliasToBean(typeof(TableName)));
IList<TableName> results = query.List<TableName>();

string hql = "SELECT column1 as {TableName.Column1}, column2 as {TableName.Column2} FROM table_name";
IQuery query = session.CreateQuery(hql);
query.SetResultTransformer(Transformers.AliasToBean(typeof(TableName)));
IList<TableName> results = query.List<TableName>();
