NHibernate不使用自定义SQL插入

我有几个NHibernate映射使用sql-insert元素来覆盖本地插入语句，但我不能得到这一个使用自定义SQL。无论我使用什么身份生成器，它都使用NHibernate的标准INSERT语句。这是我的映射文件：NHibernate不使用自定义SQL插入

<?xml version="1.0" encoding="utf-8" ?> 
     <hibernate-mapping xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" 
     xmlns:xsd="http://www.w3.org/2001/XMLSchema" 
     namespace="MyProject.Domain.Order" 
     assembly="MyProject.Domain" 
     schema="dbo" 
     xmlns="urn:nhibernate-mapping-2.2"> 
    <class name="OrderBase" table="Order" 
       polymorphism="explicit" 
       optimistic-lock="version" 
       discriminator-value="0">   
     <!--IDENTITY--> 
     <id name="Id" access="nosetter.camelcase-underscore" column="intOrderID" type="System.Int32"> 
    <generator class="native" /> 
    </id>   
     <!--TYPE DISCRIMINATOR--> 
     <discriminator formula="case when intOrderStatusID = 0 then 0 else 1 end" insert="false" type="System.Int32" />  
     <!--VERSION--> 
    <version name="DateUpdated" access="nosetter.camelcase-underscore" column="dtDateUpdated" type="Timestamp" unsaved-value="undefined" />  
     <!--PROPERTIES--> 
    <property name="TotalItems" access="nosetter.camelcase-underscore" column="intTotalItems" type="System.Int32"/> 
    <property name="TotalQuote" access="nosetter.camelcase-underscore" column="mnyTotalQuote" type="System.Decimal"/> 
     <!--ASSOCIATIONS--> 
    <many-to-one name="Account" access="nosetter.camelcase-underscore" class="MyProject.Domain.Customer.Account, MyProject.Domain" column="intAccountId" />  
    <sql-insert>exec usp_Order_Insert @p0, @p1, @p2, @p3</sql-insert> 
     </class> 
    </hibernate-mapping>

这里的SQL语句NHibernate的实际运行：

N'INSERT INTO dbo.Order (dtDateUpdated, intTotalItems, mnyTotalQuote, intAccountId) VALUES (@p0, @p1, @p2, @p3); select SCOPE_IDENTITY()',N'@p0 datetime,@p1 int,@p2 decimal(5,4),@p3 int',@p0='2010-11-29 15:39:02:480',@p1=1,@p2=4.5500,@p3=7777777

这里的存储过程：

CREATE PROCEDURE [dbo].[usp_Order_Insert] 
@dtDateUpdated datetime 
, @intTotalItems int 
, @mnyTotalQuote money 
, @intAccountId int 
AS 

BEGIN 

DECLARE @existingID int 
, @existingItems int 
, @existingMoney money 

--If the record already exists 
IF EXISTS 
(
SELECT * 
FROM Order 
WHERE intAccountID = @intAccountId 
    AND intOrderStatusID = 0 
) 
BEGIN 
    --Get the existing record details 
    SELECT @existingID = intOrderID 
    , @existingItems = intTotalItems 
    , @existingMoney = mnyTotalQuote 
    FROM Order 
    WHERE intAccountID = @intAccountId 
    AND intOrderStatusID = 0 
    --Update the existing record 
    UPDATE Order 
    SET intTotalItems = (@existingItems + @intTotalItems) 
    , mnyTotalQuote = (@existingMoney + @mnyTotalQuote) 
    , dtDateUpdated = GetDate() 
    WHERE intOrderID = @existingID 
    --Return the id of the existing record 
    SELECT intOrderID 
    FROM Order 
    WHERE intOrderID = @existingID 
END 
ELSE 
BEGIN 
    --Insert a new record 
    INSERT INTO Order 
    (
    intAccountId 
    , dtDateUpdated 
    , intTotalItems 
    , mnyTotalQuote 
) 
    VALUES 
    (
    @intAccountId 
    , @dtDateUpdated 
    , @intTotalItems 
    , @mnyTotalQuote 
) 
    --Return the new record id 
    SELECT SCOPE_IDENTITY() 
END 
END

好了，感到如此的恐慌之后，我想通了这个问题...

我没有意识到它，但我的应用程序实际上是创建一个新的实例OrderBase的子类。所以我将自定义插入语句移动到了nhibernate子类定义中，它像一个魅力一样工作。
