問題與改變，然後嘗試使用Transact-SQL更新更新

Question

這裏是我試圖通過sqlcmd（SQL Server 2005）運行的一些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 

我收到以下錯誤：

(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'. 

我猜測，這是因爲通過ALTER語句引入了新列尚未提交，以便更新失敗。

我的問題是我如何得到這個工作呢？我希望這可以作爲單個事務運行，如果出現問題，我可以回滾。這很重要，因爲我還有更多的alter語句可供使用，而且我有點沮喪，我無法克服這一點。

任何援助將不勝感激！當代碼被編譯

即使我寫我自己的答案 - 一切歸功於@Mikael埃裏克森，誰建議我需要不同批次用GO分開 - 這樣能改變表不與代碼衝突的代碼使用改變的表格。感謝Mikael！

SQL Server檢查的列。你可以使用動態sql來解決這個問題。

-- transform logic. 
declare @SQL nvarchar(1000) 
set @SQL = 
    'update dbo.RETRIEVAL_STAT set 
    SOURCE = @S, 
    ACCOUNTNUMBER = @A, 
    PUK = @P'; 

declare @Params nvarchar(1000); 
set @Params = N'@S nvarchar(10), @A nvarchar(10), @P nvarchar(20)'; 

exec sp_executesql @SQL, @Params, N'S', N'A', N'P';
