使用Transact-SQL进行Alter修改然后在tran尝试捕获中更新的问题

Question

这是一些我要通过sqlcmd（SQL Server 2005）运行的Transact-SQL。

USE PUK;
GO
BEGIN TRANSACTION;
BEGIN TRY

   -- - Modify RETRIEVAL_STAT
   alter table dbo.RETRIEVAL_STAT add
      SOURCE nvarchar(10) NULL,
      ACCOUNTNUMBER nvarchar(50) NULL,
      PUK nvarchar(20) NULL;

   -- transform logic.
   update dbo.RETRIEVAL_STAT set
      SOURCE = 'XX',
      ACCOUNTNUMBER = 'XX',
      PUK = 'XX';

END TRY
BEGIN CATCH
    SELECT
        ERROR_NUMBER() AS ErrorNumber
        ,ERROR_SEVERITY() AS ErrorSeverity
        ,ERROR_STATE() AS ErrorState
        ,ERROR_PROCEDURE() AS ErrorProcedure
        ,ERROR_LINE() AS ErrorLine
        ,ERROR_MESSAGE() AS ErrorMessage;
    IF @@TRANCOUNT > 0
        ROLLBACK TRANSACTION;
END CATCH;
IF @@TRANCOUNT > 0
    COMMIT TRANSACTION;
GO

我收到以下错误：

(0 rows affected)
Changed database context to 'PUK'.
Msg 207, Level 16, State 1, Server localhost\SQLEXPRESS, Line 11
Invalid column name 'SOURCE'.
Msg 207, Level 16, State 1, Server localhost\SQLEXPRESS, Line 11
Invalid column name 'ACCOUNTNUMBER'.
Msg 207, Level 16, State 1, Server localhost\SQLEXPRESS, Line 11
Invalid column name 'PUK'.

我猜这是因为尚未提交alter语句引入的新列，因此更新失败。

我的问题是我如何才能使它正常工作？我希望它可以作为单个事务运行，如果出现问题，我可以回滚。。这很重要，因为我要包含更多的alter语句，并且对我无法逾越这一点感到沮丧。

任何帮助将不胜感激！

即使我在写自己的答案，所有的功劳都归@Mikael Eriksson，他建议我需要用GO分开不同的批次-
这样，更改表的代码不会与使用更改后的表的代码冲突。谢谢Mikael！
