使用nhibernate执行存储过程时遇到奇怪的问题。当我通过堆栈跟踪然后我得到索引超出范围异常和属性/列的名称。我研究了谷歌和stackoverflow，发现如果任何属性被映射两次，那么它会导致问题。我检查了所有的映射，但似乎没有什么对我有帮助。 在这里，我正在编写我正在使用的所有hbl文件和代码。

我使用以下代码来调用sp。
var dd = session.GetNamedQuery("ar_tARCustomer_ReadOverdueByContext")
.SetParameter("CustomerActive", 2)
.SetParameter("CompanyID", Guid.Parse("3C5F1D66-75F3-4762-BAA1-6A0ADA8D6DD4"))
.SetParameter("PropertyID", Guid.Parse("53C4B765-C1B1-4353-98CB-AC9FBCE84F0C"))
.SetParameter("DateFrom", DateTime.Parse("5/1/2001"))
.SetParameter("DateTo", DateTime.Parse("4/24/2013"))
.SetParameter("InvoiceTypes", "Manual")
.SetResultTransformer(new AliasToBeanResultTransformer(typeof(tARCustomer)))
.SetResultTransformer(Transformers.ToList).List();
除此之外我尝试了很多组合，但我无法解决它。 我有以下存储过程。
alter PROCEDURE [dbo].[ar_tARCustomer_ReadOverdueByContext]
@CustomerActive int,
@CompanyID uniqueidentifier,
@PropertyID uniqueidentifier,
@OverdueDateFrom datetime,
@OverdueDateTo datetime,
@InvoiceTypes varchar(100)
AS
----------------------------------------------------------------------------
-- Name: ar_tARCustomer_ReadOverdueByContext
-- Purpose: Get all customers with overdue invoices matching the given criteria at this point in the hierarchy
--
-- Input: N/A
-- Output: Recordset containing all customers with overdue invoices matching the given criteria
-- Return: 0 = Success
-- >0 = Error
--
----------------------------------------------------------------------------
SET NOCOUNT ON; -
SELECT fName
from tARCustomer
我想说的另一件事是，当我使用select * from tARCustomer时，这个程序对我有用，但是当我使用来自tARCustomer的select fCustomerID时，它会给出错误。
我不知道为什么会这样，但我无法解决它。请帮我尽快解决这个问题，
这里我将堆栈跟踪异常。

感谢。
答案 0 :(得分：0)
当您对查询结果使用AliasToBeanResultTransformer时，查询中返回的列必须与您要加载数据的类的属性一对一映射。
您在上面发布的查询只返回一列fName1 - 它缺少您的班级tARCustomer的所有其他属性。
抛出的异常告诉您问题 - 它无法找到结果列fCustomerID。为了说明修改你的select语句以包含它并重新运行它，异常将突出显示下一个缺失的字段。
