在SQL Server 2005中使用XML时,为什么必须设置ARITHABORT?

在SQL Server 2005中使用XML时,为什么必须设置ARITHABORT? 我试着研究为什么我必须设置这个,但找不到一个答案告诉我为什么。只是需要设置。

以下是我在联机取出set arithabort时得到的特定错误消息:

参数错误:无法分析插入列表-插入失败 因为以下设置选项的设置不正确: “算术异常”。验证set选项是否正确用于indexed 计算列和/或查询通知上的视图和/或索引 和/或XML数据类型方法。

我的存储过程在一个环境中使用ODBC从ASP.NET调用时运行良好。然后,当我将它移到另一个存储过程时,我必须在存储过程的开头添加set arithabort。我在下面包括存储过程的相关部分。以及调用它的代码。

CREATE PROCEDURE [dbo].[myproc]
   @ruserid             varchar(8),
   @folder_list         xml,
   @insert_list         xml
AS

SET NOCOUNT ON
SET ARITHABORT ON

DECLARE @rindex integer
DECLARE @errormsg nvarchar(4000)
DECLARE @folder_cnt integer
DECLARE @insert_cnt integer


SET @rindex = -1

-- insert inserts to make sure data is compatible in type
BEGIN TRY
   INSERT INTO #insert_list (insertdesc, insertfolder)
   SELECT insert_list.listitem.value('@insertdesc', 'varchar(96)'), insert_list.listitem.value('@insertfolder', 'integer')
   FROM @insert_list.nodes('/Root/Insert') AS insert_list(listitem)
END TRY
BEGIN CATCH
   SET @errormsg = N'PARAMETER ERROR: INSERT LIST COULD NOT BE PARSED - ' + ERROR_MESSAGE()
   RAISERROR(@errormsg, 16, 1)
   RETURN
END CATCH

   INSERT INTO #folder_list (insertfolder, folderdesc)
   SELECT folder_list.listitem.value('@insertfolder', 'integer'), folder_list.listitem.value('@folderdesc', 'varchar(144)')
   FROM @folder_list.nodes('/Root/Folder') AS folder_list(listitem)
END TRY
BEGIN CATCH
   SET @errormsg = N'PARAMETER ERROR: FOLDER LIST COULD NOT BE PARSED - ' + ERROR_MESSAGE()
   RAISERROR(@errormsg, 16, 1)
   RETURN

SELECT @rindex, #folder_list.insertfolder, #folder_list.folderdesc

   RAISERROR(@errormsg, 16, 1)
   RETURN

   COMMIT TRANSACTION

-- return result
SELECT @rindex AS rindex

DROP TABLE #insert_list
DROP TABLE #folder_list

GO           

调用代码

  ' build odbc command for inserting creation request

  cmdAddRequest = New System.Data.Odbc.OdbcCommand
  cmdAddRequest.CommandType = CommandType.StoredProcedure
  cmdAddRequest.CommandTimeout = 60
