Ошибка T-SQL: ALTER VIEW в блоке транзакции и try-catch

Question

Я использую SQL Server 2005 и SQL Server 2005 Management Studio Express. У меня есть сценарий с нижеприведенной схемой:

USE [MyDatabase] 
GO 
SET ANSI_NULLS ON 
GO 
SET QUOTED_IDENTIFIER ON 
GO 

BEGIN TRANSACTION; 
GO 

BEGIN TRY 
    ALTER VIEW dbo.MyView 
    AS 
    SELECT ... 
    GO 
    ALTER TABLE ... 
    GO 
    UPDATE dbo.MyTable ... 
    GO 
    INSERT INTO dbo.AnotherTable ... 
    GO 
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 

Проблема заключается в том, что я получаю сообщение об ошибке в блоке ALTER VIEW dbo.MyView: «Неправильный синтаксис около зарезервированного слова„VIEW“.»

Answer 1

Это не дало мне синтаксической ошибки, попробуйте это. Я просто удалил «Go» в конце динамического sql.

USE [MyDatabase] 
go 
SET ANSI_NULLS ON 
go 
SET QUOTED_IDENTIFIER ON 
go 
BEGIN TRANSACTION 
go 
BEGIN TRY 
EXEC sp_executesql N'ALTER VIEW dbo.MyView 
AS 
SELECT * FROM ....; ' 
EXEC sp_executesql N'ALTER TABLE ...;' 
EXEC sp_executesql N'UPDATE ....;' 
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
