流畅的 NHibernate 和存储过程
我有一个基本的客户/订单/订单项目/产品对象图。客户有很多订单,订单有很多订单项目,产品有很多订单项目。这些已使用 FNH 成功映射。
我在配置存储过程和存储过程时遇到了障碍。流畅的休眠。在 fluid-hibernate FNH(版本 1.0 RTM)中没有映射存储过程的本机方法。有一个解决方案 此处有关向类映射添加部件的信息,但 AddPart 调用已从 FNH 版本中删除。
存储过程很简单:
CREATE PROCEDURE [dbo].[OrderCountByCustomer]
AS
BEGIN
SET NOCOUNT ON;
SELECT
c.name as [Customer.Name],
CAST(count(o.id) as NVARCHAR) as [Customer.OrderCount]
FROM customer c
LEFT OUTER JOIN [order] o
ON o.customer_id = c.id
GROUP BY c.name
END
这里有一个 CustomerOrderSummary.hbm.xml
<?xml version="1.0" encoding="utf-8" ?>
<hibernate-mapping xmlns="urn:nhibernate-mapping-2.2" assembly="NVAble.Orders.Core" namespace="NVAble.Orders.Core">
<sql-query name="OrderSummary">
<return class="CustomerOrderSummary">
<return-property column="Customer.Name" name="CustomerName" />
<return-property column="Customer.OrderCount" name="OrderCount" />
</return>
EXEC [OrderCountByCustomer]
</sql-query>
</hibernate-mapping>
这是 CustomerOrderSummary 类 def:
namespace NVAble.Orders.Core
{
public class CustomerOrderSummary
{
virtual public string CustomerName { get; set; }
virtual public string OrderCount { get; set; }
public override string ToString()
{
return string.Format("{0} {1}", CustomerName, OrderCount);
}
}
}
但是,当尝试启动 NH 会话时,我在命名查询 OrderSummary
中收到错误,没有其他详细信息。
我可能缺少一些非常简单的东西,将 CustomerOrderSummary 类映射到过程,我不知道。该域对象显然不会直接映射到数据库中的表,因此我不确定正常的
HBM 映射是否有效?
提前致谢!
I have a basic Customer/Order/OrderItem/Product object graph. Customer has Many Orders, Order has Many Order Items, Product has many Order Items. These are successfully mapped using FNH.
I've hit a snag with configuring a stored procedure & fluent-nhibernate. There is not a native way to map stored procedures in fluent-hibernate FNH (version 1.0 RTM). There was a solution here about adding parts to class mappings but the AddPart call has been taken out of the release of FNH.
The stored procedure is simple:
CREATE PROCEDURE [dbo].[OrderCountByCustomer]
AS
BEGIN
SET NOCOUNT ON;
SELECT
c.name as [Customer.Name],
CAST(count(o.id) as NVARCHAR) as [Customer.OrderCount]
FROM customer c
LEFT OUTER JOIN [order] o
ON o.customer_id = c.id
GROUP BY c.name
END
There's a CustomerOrderSummary.hbm.xml in
<?xml version="1.0" encoding="utf-8" ?>
<hibernate-mapping xmlns="urn:nhibernate-mapping-2.2" assembly="NVAble.Orders.Core" namespace="NVAble.Orders.Core">
<sql-query name="OrderSummary">
<return class="CustomerOrderSummary">
<return-property column="Customer.Name" name="CustomerName" />
<return-property column="Customer.OrderCount" name="OrderCount" />
</return>
EXEC [OrderCountByCustomer]
</sql-query>
</hibernate-mapping>
Here is the CustomerOrderSummary class def:
namespace NVAble.Orders.Core
{
public class CustomerOrderSummary
{
virtual public string CustomerName { get; set; }
virtual public string OrderCount { get; set; }
public override string ToString()
{
return string.Format("{0} {1}", CustomerName, OrderCount);
}
}
}
However, when try to start a NH session i get error in named query OrderSummary
with no other details.
I'm probably missing something really simple that maps the CustomerOrderSummary
class to the procedure, I don't know. That domain object obviously doesn't map directly to a table in the data base so I'm unsure if having a normal <class />
HBM mapping would work?
Thanks in advance!

好的,经过更多调查后。我需要域类的映射以及命名查询 hbm.xml 文件。
在我的配置类中,我
唯一的缺点是我需要手动创建存储过程的 xml 映射,目前我无法使用 FNH
Ok, so after a bit more investigation. I needed a mapping for the Domain Class as well as a named query hbm.xml file.
In my configure class i have
Only downside is that I need to manually create the xml mapping for the stored procedure, I can't use FNH at the current time
