我在 Nhibernate 中使用命名查询调用过程时遇到了一些问题。我可以轻松调用简单过程/参数化过程，但我有接受三个参数的过程，一个是 varchar(max) 类型，它的 guid 用逗号分隔（这作为参数传递给 SQL 查询），另一个是 varchar(50) 和最后一个是位类型。

我有以下程序：

CREATE PROCEDURE [dbo].[ar_tARCustomer_ReadAccount_ForBalanceDetail]    

 @CustomerList varchar(max),    
 @AsOfDate  varchar(50),    
 @PostedOnly  bit    

AS    



SET NOCOUNT ON;    

Declare @ErrorNumber int    
Declare @SQL   varchar(max)    
Declare @PostedInvoice varchar(50)    
Declare @PostedPayment varchar(200)    

SET @PostedInvoice = ''    
SET @PostedPayment=  ''    
IF (@PostedOnly = 1)    
BEGIN    
 SET @PostedInvoice = ' And ari.fIsPosted = 1 '    
 SET @PostedPayment = ' And pay.fIsPosted =     
   CASE pay.fPaymentType    
     WHEN ''CM'' THEN 0    
     WHEN ''EPD'' THEN 0    
     ELSE 1    
   END'    
END    

Set @SQL =     
'    
select * from    
(    
 Select Distinct    
   co.fName as fTrxCompanyName, prop.fName as fTrxPropertyName, arc.fName as fTrxCustomerName,       
   cast(ari.fARInvoiceNumber  as varchar(10)) as fTrxNumber,    
   ari.fInvoiceDescription as fTrxDescription,    
   ari.fIsVoided as fTrxIsVoided,    
   CASE fInvoiceType    
     WHEN ''Credit Memo'' THEN fBalance    
     WHEN ''Early Payment Discount'' THEN fBalance    
     ELSE fAmount    
   END as fTrxAmount    
 From tARInvoice ari    
  Inner Join tARCustomer arc on arc.fCustomerID = ari.fCustomerID    
  LEFT OUTER JOIN tSCCompany co on co.fCompanyID = arc.fCompanyID    
  LEFT OUTER JOIN tSCProperty prop on prop.fPropertyID = arc.fPropertyID     
 Where ari.fCustomerID in (' + @CustomerList + ') and    
    ari.fInvoiceDate >= convert(datetime,'+ '''' + @AsOfDate + '''' + ') and    
    ari.fInvoiceType <> ''Recurring Template''' + @PostedInvoice + '

            pay.fAmount as fTrxAmount

  Left Outer Join tARPaymentInvoice payinv On pay.fPaymentID = payinv.fPaymentID

  Left Outer Join tARCustomer cust on cust.fCustomerID = pay.fCustomerID    
  LEFT OUTER JOIN tSCCompany co on co.fCompanyID = cust.fCompanyID    
  LEFT OUTER JOIN tSCProperty prop on prop.fPropertyID = cust.fPropertyID      
 Where (inv.fCustomerID IN (' + @CustomerList +')

我已将以下代码写入 hbm 文件。

<sql-query name="ar_tARCustomer_ReadAccount_ForBalanceDetail_New" callable="true">
    <!--<query-param name="CustomerList" type="VARCHAR(max)" />
    <query-param name="AsOfDate" type="string" />
    <query-param name="PostedOnly" type="bool" />-->
    <return class="tARCustomer">
      <return-property column="fTrxCompanyName" name="fTrxCompanyName" />
      <return-property column="fTrxPropertyName" name="fTrxPropertyName" />
      <return-property column="fTrxCustomerName" name="fTrxCustomerName" />
      <return-property column="fCustomerID" name="fTrxCustomerID" />
      <return-property column="fTrxSourceID" name="fTrxSourceID" />
      <return-property column="fInvoicePosted" name="fInvoicePosted" />
      <return-property column="fTrxDate" name="fTrxDate" />
      <return-property column="fPostedDate" name="fPostedDate" />
      <return-property column="fTrxType" name="fTrxType" />
      <return-property column="fTrxDueDate" name="fTrxDueDate" />
      <return-property column="fTrxAddedDate" name="fTrxAddedDate" />
      <return-property column="fTrxBalance" name="fTrxBalance" />
      <return-property column="fTrxDescription" name="fTrxDescription" />
      <return-property column="fTrxIsVoided" name="fTrxIsVoided" />
      <return-property column="fTrxAmount" name="fTrxAmount" />
    </return>

    exec ar_tARCustomer_ReadAccount_ForBalanceDetail_New
    @CustomerList=:CustomerList,
    @AsOfDate=:AsOfDate,
    @PostedOnly=:PostedOnly
  </sql-query>

为了调用这个程序，我编写了以下代码。

var Customerbalance = Session.GetNamedQuery("ar_tARCustomer_ReadAccount_ForBalanceDetail_New")
                                           .SetParameter("CustomerList", "'''bced443a-ce86-4675-bca6-ae5646ad9c2e'' , ''bced443a-ce86-4675-bca6-ae5646ad9c2e'''")
                                           .SetParameter("AsOfDate", "10/1/2012")
                                           .SetParameter("PostedOnly", PostedOnly)
                                           .SetResultTransformer(new AliasToBeanResultTransformer(typeof(tARCustomer))).List<tARCustomer>();

在这里，我尝试了所有类型的组合来使用 NHibernate 将参数传递给过程，但它总是崩溃。

尝试将 sql-query 的 EXEC 嵌入到 BEGIN/END 块中：

BEGIN
    EXEC ar_tARCustomer_ReadAccount_ForBalanceDetail_New .. params ..
END

至少这就是我让它在 NH 3.2 Mapping.ByCode 中工作的方式。
