流畅的NHibernate QueryOver没有返回预期的数据？ （Oracle）的

我有一个班级：

public class WorkOrderStatusTracking {
  private WorkOrderStatusTracking_ID _id = new WorkOrderStatusTracking_ID();
  public virtual WorkOrderStatusTracking_ID ID {
    get { return _id; }
    set { _id = value; }
  }
  public virtual String WORK_ORDER_NBR { get; set; }
  public virtual String WORK_ORDER_TASK { get; set; }
  public virtual Int32 GEN_ARG { get; set; }
  public virtual String HOLD_CODE { get; set; }
  public virtual String HOLD_RELEASE_DATE { get; set; }
}

复合ID：

public class WorkOrderStatusTracking_ID {
  public virtual String WORK_ORDER_NBR { get; set; }
  public virtual String WORK_ORDER_TASK { get; set; }
  public virtual Int32  GEN_ARG { get; set; }
  public override bool Equals(object obj) {
    if (obj == null) {
      return false;
    }
    var t = obj as WorkOrderStatusTracking_ID;
    if (t == null) {
      return false;
    }
    if (
      (WORK_ORDER_NBR == t.WORK_ORDER_NBR) &&
      (WORK_ORDER_TASK == t.WORK_ORDER_TASK) &&
      (GEN_ARG == t.GEN_ARG)
    ) {
      return true;
    }
    return false;
  }
  public override int GetHashCode() {
    return String.Format("{0}|{1}|{2}",
      WORK_ORDER_NBR,
      WORK_ORDER_TASK,
      GEN_ARG
    ).GetHashCode();
  }  
}

和班级地图：

public class WorkOrderStatusTracking_ORM : ClassMap<WorkOrderStatusTracking> {
  public WorkOrderStatusTracking_ORM() {
    Table("TIDWOSTR");
    CompositeId(x => x.ID)
      .KeyProperty(x => x.WORK_ORDER_NBR, x => x.Length(8))
      .KeyProperty(x => x.WORK_ORDER_TASK, x => x.Length(2))
      .KeyProperty(x => x.GEN_ARG);
    Map(x => x.WORK_ORDER_NBR).Length(8);
    Map(x => x.WORK_ORDER_TASK).Length(2);
    Map(x => x.GEN_ARG);
    Map(x => x.HOLD_CODE).Length(3);
    Map(x => x.HOLD_RELEASE_DATE).Length(8);
  }
}

然而，当我跑：

List<WorkOrderStatusTracking> WorkOrderStatusTrackings = session.QueryOver<WorkOrderStatusTracking>()
  .Where(x => x.WORK_ORDER_NBR == "00322384")
  .List<WorkOrderStatusTracking>().ToList();

foreach (WorkOrderStatusTracking w in WorkOrderStatusTrackings) {
  Console.WriteLine(...);
}

我得到零结果......

现在我知道这个where子句存在一个事实条目，如果我.ShowSql（）并将查询复制到SQL Developer（这是一个Oracle数据库）它肯定会返回行，此外如果我删除我的.Where（）并且放入.Take（10），我得到记录回来。有人有主意吗？尽管生成的查询在SQL Developer中工作，为什么.Where不起作用？

log4net结果：

我能够通过设置NHibernate来使用Oracle的.NET提供程序而不是默认的.NET提供程序。为了做到这一点，我必须做以下事情：

1. Download and unzip/install the appropriate Oracle Data Access Components, in my case the 32bit ODAC for Oracle 11g (ODAC112040Xcopy_32bit.zip).
2. Add a reference to the Oracle.DataAccess.dll found in the .\odp.net20\odp.net\bin\2.x directory.
3. Copy the OraOps11w.dll found in the .\odp.net20\bin directory directly to my projects bin directory.
4. Copy the following DLLs to my projects bin directory (not 100% sure which of these are necessary, I just copied them all)
    .\instantclient_11_2\oci.dll
    .\instantclient_11_2\ocijdbc11.dll
    .\instantclient_11_2\ociw32.dll
    .\instantclient_11_2\orannzsbb11.dll
    .\instantclient_11_2\oraocci11.dll
    .\instantclient_11_2\oraociei11
    .\instantclient_11_2\orasql11
5. Updated my fluent configuration of NHibernate to use the Oracle driver as such:
      Fluently.Configure()
       .Database(OracleClientConfiguration.Oracle10.ConnectionString(OraConStr).Driver<NHibernate.Driver.OracleDataClientDriver>())
       .Mappings(m => m.FluentMappings.AddFromAssemblyOf<Program>())
       .BuildSessionFactory();

一旦进行了这些更改，所有表访问都能正常工作，并且工作速度更快。因此，我要将此问题归结为提供商/驱动程序问题。我只能假设NHibernate默认使用内置的Microsoft System.Data.OracleClient提供程序，该提供程序已经折旧了一段时间。

虽然这并不能解释为什么当我直接在NHibernate之外使用微软的提供商时，我能够很好地访问该表。在我将项目推向客户的大门之后，我可能会对此进行进一步的研究，因为这是一个令人费解的困境，我无法解决一个好的难题。

也适用于.Net 4.0。
