求解:nhibernate2.0操作oralce提交事务时报错

代码如下:

  Configuration config = new Configuration();
                config.AddAssembly("TestCleanSnow");
               
               
                ISessionFactory factory = config.BuildSessionFactory();
                ISession session = factory.OpenSession();

              

                TestNhibernate tn = new TestNhibernate();
                tn.Id = Decimal.Parse("2");
                tn.Name = "terry wang";
               ITransaction trans = session.BeginTransaction();
           try
           {             

               session.Save(tn);
               trans.Commit();
              
               Console.WriteLine("Insert Success!");
           }
           catch (Exception ex)
           {
               trans.Rollback();
               Console.WriteLine(ex.Message);
           }

 

执行到trans.Commit()时出错,

出错信息如下:

NHibernate.HibernateException :"could not insert: [TestCleanSnow.TestNhibernate][SQL: INSERT INTO TEST_NHIBERNATE ([NAME], ID) VALUES (?, ?)]"}

InnerText:ORA-00928: 缺少 SELECT 关键字

我在控制台调试看到输出NHibernate的语句是: INSERT INTO TEST_NHIBERNATE ([NAME], ID) VALUES (:p0, :p1); :p0 = 'terryerry wang', :p1 = '2'

请问是哪里出错?
