在C＃中使用命名查询的NHibernate调用过程

Question

I am facing some problem while calling procedure using named query in Nhibernate. I can easily call simple procedure / parametrized procedure but I have procedure which accept three argument, one is varchar(max) type which have guid seperated by commas (this is passed as in parameter to SQL query), other is varchar(50) and last one is bit type.

I have following procedure:

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

I had written following code into hbm file.

<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="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>

And for calling this procedure I had written following code.

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>();

Here I had tried all type of combination for passing parameter to procedure using NHibernate but it always crashed.

Answer 1

Try embedding the EXEC of your sql-query inside a BEGIN/END block:

BEGIN
    EXEC ar_tARCustomer_ReadAccount_ForBalanceDetail_New .. params ..
END

At least that's how I got it to work in NH 3.2 Mapping.ByCode.
