C# NHibernate OleDB:使用会话时程序绑定无效。get<；T>；（id）

我第一次使用NHibernate。我已经将其设置为使用OleDB连接到SQLBase数据库。我已经设置了一些类，现在尝试第一个简短的测试，看看它是否有效

这是我的测试：

[TestClass]
public class Hibernate
{
    private ISessionFactory _sessionFactory;
    private Configuration _config;

    [TestInitialize]
    public void InitTest()
    {
        _config = new Configuration();
        _config.Configure();
        _config.AddAssembly(typeof(Coil).Assembly);
        _sessionFactory = _config.BuildSessionFactory();
    }


    [TestMethod]
    public void TestMethod1()
    {
        using (var session = _sessionFactory.OpenSession())
        {
            Int32 coilid = 12189;
            Coil coil = session.Get<Coil>(coilid);
            Assert.AreEqual(coil.CoilNumber, "6FEB13");
        }
    }
}

线圈表的创建表语法如下所示：

CREATE TABLE COIL (
  COILID INTEGER NOT NULL, 
  COILNR VARCHAR(50), 
);

Edit5：查询所有条目都有效，但只要我想从表中获得一个特定条目，我就会得到？再次出错：(

但是SQLbase需要准备好的字符串，比如

WHERE coil0_.COILID = :0
\
12189
/

---

要改变nhibernate将绑定变量转换为SQL的方式，我必须做些什么？

我可以通过为SQLBase编写自己的驱动程序和方言（分别来自OleDbDriver和GenericDialogue）来解决这个问题。如果其他人需要将SQLBase与NHibernate一起使用，我可以发布代码。

您可以发布stacktrace的其余部分吗？可能是类型不匹配。db中的整数是有符号的还是无符号的？我将在周一回到办公室后发布整个stacktrace。我在测试中编辑了stacktrace。它看起来像个bug。如果您想调试它，请您可以实现自己的批处理程序继承nobatching批处理程序，并截取

ExecuteReader（）

查看命令，如果有参数设置作为解决方法，请将

batcher.ExecuteReader（）

中的占位符替换为适当的占位符
