全部，

我希望有人可以帮助我尝试使用 IronPython 和 CLR 运行存储过程。

我要做的就是让下面的存储过程运行。当它运行并到达 ExecuteNonQuery 行时，它会跳转到 SQLException 但我无法检索消息告诉我的内容。我显然做错了什么，但我无法弄清楚。

下面是来自 SQL Server 的存储过程（仅供参考 - 我没有更改过程；仅用于复制/粘贴目的）：

/****** Object:  StoredProcedure [dbo].[spAddControlLimit]    Script Date: 4/5/2021 8:26:04 AM ******/
SET ANSI_NULLS ON
GO

SET QUOTED_IDENTIFIER ON
GO


ALTER PROCEDURE [dbo].[spAddControlLimit]
    -- Add the parameters for the stored procedure here
    @CLID nvarchar(max)
    ,@PLANTCODE nvarchar(4)
    ,@IC nvarchar(max)
    ,@PropertyDescription nvarchar(max)
    ,@PropertyCode nvarchar(max)
    ,@LN nvarchar(max)
    ,@SpecID nvarchar(max)
    ,@UCL numeric(11,4)
    ,@LCL numeric(11,4)
    ,@TargetMean numeric(11,4)
    ,@SetBy nvarchar(max)
    ,@SetDate datetime
    ,@Comments varchar(255)
AS
BEGIN
    -- SET NOCOUNT ON added to prevent extra result sets from
    -- interfering with SELECT statements.
    SET NOCOUNT ON;

    -- Insert statements for procedure here
    INSERT INTO [dbo].[SPC_CALCULATED_CONTROL_LIMITS]
               ([ControlLimitID]
               ,[PLANT_CODE]
               ,[ITEM_CODE]
               ,[PROPERTY_DESC]
               ,[PROPERTY_CODE]
               ,[LineNumber]
               ,[SpecID]
               ,[UpperControlLimit]
               ,[LowerControlLimit]
               ,[TargetMean]
               ,[SetBy]
               ,[SetDate]
               ,[Comments])
         VALUES
               (@CLID
               ,@PLANTCODE
               ,@IC
               ,@PropertyDescription
               ,@PropertyCode
               ,@LN
               ,@SpecID
               ,@UCL
               ,@LCL
               ,@TargetMean
               ,@SetBy
               ,@SetDate
               ,@Comments)
END
GO

这是应该执行该存储过程的 IronPython 代码：

import clr

clr.AddReference("System.Windows.Forms")
clr.AddReference("System.Drawing")
clr.AddReference("System.Data")
clr.AddReference("System.Globalization")
clr.AddReference('System.Collections')
clr.AddReference('System')

                data_list.append(r.Cells[1].Value.ToString())
                data_list.append(r.Cells[2].Value.ToString())
                data_list.append(r.Cells[3].Value.ToString())

                data_list.append(r.Cells[5].Value.ToString())
                data_list.append(r.Cells[6].Value.ToString())
                data_list.append(r.Cells[7].Value.ToString())
