我是NHibernate的新手,所以我不确定我做错了什么。我目前收到此消息:
无法插入: [NhibernateTest.Domain.Order#5ed0d146-644b-44ff-A080-f8cf3048158e] [SQL: INSERT INTO Order(OrderName,ShippingAddress,ShippingDate,OrderID) 价值观(?,?,?,?)]
我正在尝试对我的数据库进行基本插入,该数据库只有一个表。
我的域名:
public class Order
{
public virtual Guid OrderID { get; set; }
public virtual string Name { get; set; }
public virtual string ShipAddress { get; set; }
public virtual string ShipDate { get; set; }
public Order()
{
}
public Order(string name, string shipAddress, string shipDate)
{
Name = name;
ShipAddress = shipAddress;
ShipDate = shipDate;
}
}
我的映射:
<?xml version="1.0" encoding="utf-8" ?>
<hibernate-mapping xmlns="urn:nhibernate-mapping-2.2" assembly="NhibernateTest" namespace="NhibernateTest.Domain">
<class name="Order" table="Order" lazy="true">
<id name="OrderID" column="OrderID">
<generator class="guid" />
</id>
<property name="Name" column="OrderName" type="string" />
<property name="ShipAddress" column="ShippingAddress" type="string" />
<property name="ShipDate" column="ShippingDate" type="string" />
</class>
</hibernate-mapping>
我的OrderRepository:
public void Add(Order order)
{
/* Open up a session to the database. */
using (ISession session = NHibernateHelper.OpenSession())
{
/* Open up a transaction to the database since an order object will be added. */
using (ITransaction transaction = session.BeginTransaction())
{
session.Save(order);
transaction.Commit();
}
}
}
这是我的AddMethod以及我的loadCfg函数:
[HttpPost]
public ActionResult AddOrder(FormCollection form)
{
LoadNHibernateCfg();
OrderRepository repo = new OrderRepository();
var order = new Order { Name = form[0], ShipAddress = form[1], ShipDate = form[2] };
//order.Name = form[0];
//order.ShipAddress = form[1];
//order.ShipDate = form[2];
repo.Add(order);
return Index();
}
public static void LoadNHibernateCfg()
{
var cfg = new Configuration();
cfg.Configure();
cfg.AddAssembly(typeof (Order).Assembly);
new SchemaExport(cfg).Execute(true, false, true);
}
我知道订单对象在传递给.Add-function时有信息。所以我认为它必须与我的映射有关?

Order
是保留关键字。例如,在查询内容时使用Order by
。以下是所有保留字的列表:http://msdn.microsoft.com/en-us/library/aa238507%28v=sql.80%29.aspx
您只需更改表名和映射即可解决此问题。例如,您可以为表格Orders
命名:
<class name="Order" table="Orders" lazy="true">

我收到错误:无法插入:[RegEmails.Model.RegInfo] [SQL:INSERT INTO reg_info(MESSAGE_HASH,IS_INTERNAL,PRODUCT,SERVER,VERSION,MODULE,BRIDGE_LICENCE,BRIDGE_LICENCE_EXPIRY,BACK_OFFICE_LICENCE,BACK_OFFICE_LICENCE_EXPIRY,COMMENT,CREATE_DATE)价值观(?,?,?,?,?,?,?,?,?,?,?,?)]
我有类似的东西
<id name="info_id" column="INFO_ID">
<generator class="identity" />
</id>
<property name="MessageHash" column="MESSAGE_HASH" length="512" />
<property name="IsInternal" column="IS_INTERNAL" />
<property name="Product" column="PRODUCT" />
<property name="Server" column="SERVER" />
<property name="Version" column="VERSION" />
<property name="Module" column="MODULE" />
<property name="BridgeLicence" column="BRIDGE_LICENCE" />
<property name="BridgeLicenceExpiry" column="BRIDGE_LICENCE_EXPIRY" />
<property name="BackofficeLicence" column="BACK_OFFICE_LICENCE" />
<property name="BackofficeLicenceExpiry" column="BACK_OFFICE_LICENCE_EXPIRY" />
<property name="Comment" column="COMMENT" />
<property name="CreateDate" column="CREATE_DATE" />
InnerException:'字段列表'中的未知列'MESSAGE_HASH'
我通过删除解决了
<id name="info_id" column="INFO_ID">
<generator class="identity" />
</id>
<property name="MessageHash" length="512" />
<property name="IsInternal" />
<property name="Product" />
<property name="Server" />
<property name="Version" />
<property name="Module" />
<property name="BridgeLicence" />
<property name="BridgeLicenceExpiry" />
<property name="BackofficeLicence" />
<property name="BackofficeLicenceExpiry" />
<property name="Comment" />
<property name="CreateDate" />
