Question

以下是我试图通过sqlcmd运行的一些Transact-SQL（SQL Server 2005）。

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alter语句引入的新列尚未提交，因此更新失败。

我的问题是如何才能让它工作呢？我希望这个作为单个事务运行，如果出现问题我可以回滚。这很重要，因为我还有更多的alter语句包括在内，而且我有点沮丧，我无法超越这一点。

非常感谢任何帮助！

即使我正在编写自己的答案 - 所有的归功于@Mikael Eriksson，他建议我需要将不同的批次与GO分开 - 以便改变表格的代码不会与使用更改的代码冲突表。谢谢Mikael！

SQL Server在编译代码时检查列。您可以使用动态SQL来解决该问题。

-- 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';

使用Transact-SQL在try catch with tran中更改然后更新的问题
