我在带有 Oracle 8i 客户端的旧数据库上使用 NHibernate。我可以对数据库表执行 Get 和 Delete，但不能保存或更新条目。例外情况如下， sqlString 由问号组成，我不知道为什么。
Nhibernate.Exceptions.GenericADOException:
{"could not update: [MIAP.Domain.Entities.MITFORG#3][SQL: UPDATE MITFORG SET TREELEVEL = ?, PARTENTID = ?, FORGNAME = ?, FORGINFO = ?, ACTIVE = ?, MUTATOR = ?, INPDATETIME = ?, UPDDATETIME = ? WHERE FORGID = ?]"}
这是我的实体类和映射：
public class MITFORG {
private long fORGID;
private long? tREELEVEL;
private long? pARTENTID;
private string fORGNAME;
private string fORGINFO;
private string aCTIVE;
private long? mUTATOR;
private DateTime? iNPDATETIME;
private DateTime? uPDDATETIME;
public MITFORG() { }
public virtual long FORGID {
get {
return this.fORGID;
}
set {
this.fORGID = value;
}
}
public virtual long? TREELEVEL
{
get {
return this.tREELEVEL;
}
set {
this.tREELEVEL = value;
}
}
public virtual long? PARTENTID
{
get {
return this.pARTENTID;
}
set {
this.pARTENTID = value;
}
}
public virtual string FORGNAME {
get {
return this.fORGNAME;
}
set {
this.fORGNAME = value;
}
}
public virtual string FORGINFO {
get {
return this.fORGINFO;
}
set {
this.fORGINFO = value;
}
}
public virtual string ACTIVE {
get {
return this.aCTIVE;
}
set {
this.aCTIVE = value;
}
}
public virtual long? MUTATOR
{
get {
return this.mUTATOR;
}
set {
this.mUTATOR = value;
}
}
public virtual DateTime? INPDATETIME
{
get {
return this.iNPDATETIME;
}
set {
this.iNPDATETIME = value;
}
}
public virtual DateTime? UPDDATETIME
{
get {
return this.uPDDATETIME;
}
set {
this.uPDDATETIME = value;
}
}
}

我检查了属性名称和表列名称。由于 FORGID 是由应用程序分配的，因此我将生成器类更改为“已分配”。它也不适用于“身份”。有人可以指点我调试这个的方向吗？
已编辑：保存条目的代码
Dim mitforgRepository As New MITFORGRepository
Dim mitforg As MITFORG = mitforgRepository.GetById(3)
mitforg.FORGINFO = "T"
mitforg.ACTIVE = "Y"
mitforg.FORGINFO = "T"
mitforg.INPDATETIME = Now
mitforg.MUTATOR = 324
mitforg.PARTENTID = 335
mitforg.TREELEVEL = 1
mitforg.UPDDATETIME = Now
mitforgRepository .Save(mitforg)
这是存储库类：
using System;
using System.Collections.Generic;
using System.Text;
using NHibernate;
using MIAP.Domain.Entities;
namespace MIAP.Domain.Repositories
{
public class MITFORGRepository : IRepository<MITFORG, Int64?>
{
private static ISession GetSession()
{
return SessionProvider.SessionFactory.OpenSession();
}
public MITFORG GetById(Int64? id)
{
using (ISession session = GetSession())
{
return session.Get<MITFORG>(id);
}
}
public void Save(MITFORG saveObj)
{
using (ISession session = GetSession())
{
using (ITransaction trans = session.BeginTransaction())
{
session.SaveOrUpdate(saveObj);
trans.Commit();
}
}
}
public void Delete(MITFORG delObj)
{
using (ISession session = GetSession())
{
using (ITransaction trans = session.BeginTransaction())
{
session.Delete(delObj);
trans.Commit();
}
}
}
}
}
InnerException 是 System.Data.OracleClient.OracleException，ORA-12571
