内存中的SqLite数据库和NHibernate

我让nhibernate处理oracle数据库，我正在尝试使用sqlite内存数据库来测试我们的查询逻辑。我相信我已经阅读、理解并确认了网络上关于这个问题的每一个答案，其中一些答案已经过几次：）

我得到的SQLite错误没有这样的表： 我在SchemaExport调用中也没有看到任何ddl命令

这里是我的设置，我觉得是相关的位。 这段代码都来自同一个方法

cfg = new Configuration()
.SetProperty(Environment.ReleaseConnections, "on_close")
.SetProperty(Environment.Dialect, typeof(SQLiteDialect).AssemblyQualifiedName)
.SetProperty(Environment.ConnectionDriver, typeof(SQLite20Driver).AssemblyQualifiedName)
.SetProperty(Environment.ConnectionString, "Data Source=:memory:;Version=3;New=True")
.SetProperty(Environment.ProxyFactoryFactoryClass, typeof(ProxyFactoryFactory).AssemblyQualifiedName)
.SetProperty(Environment.ShowSql, "true")
.SetProperty(Environment.ConnectionProvider, typeof(NHibernate.Connection.DriverConnectionProvider).AssemblyQualifiedName);
cfg.AddAssembly("MyAssembly");
_sessionFactory = cfg.BuildSessionFactory();
_session = _sessionFactory.OpenSession();
new SchemaExport(cfg).Execute(true, true, false, _session.Connection, Console.Out); <--don't see any ddl commands here
var q = from c in _session.Query<ComponentGroup>()
where !c.IsDiscontinued
select c;
var z = q.ToList(); //<--get error here

内部异常

  InnerException: System.Data.SQLite.SQLiteException

我使用的是NHibernate版本3.1.0.4，System.Date.SQLite版本2.0.50727，因此修复程序将替换 newschemaexport（cfg）.Execute（true，true，false，_session.Connection，Console.Out）； 具有 newschemaexport（cfg）.Execute（true，true，false，_session.Connection，null）

我真的不知道为什么，但我添加了代码，将行插入到导出的表中，正如预期的那样

然后我将控制台.Out parm放回，得到一个“无法写入已关闭的TextWriter”错误。

您能检查一下您的hbm.xml映射是否真的设置为embedded resource吗？事实上，同一个hbm可用于oracle会话

public class ComponentGroup
{
    public virtual int Id { get; set; }
    public virtual int AssemblyFacilityId { get; set; }
    public virtual string Name { get; set; }
    public virtual bool IsDiscontinued { get; set; }
}
