Question

基本上我想保持事务非常简单，但是如果在后面的部分中发生任何错误，我应该能够回滚。类似的东西：

BEGIN TRANSACTION

  DELETE SET 1(this will delete first set of table)
  COMMIT

  DELETE SET 2 (will delete second set of table)

如果在删除set 2时发生任何错误，我也应该能够回滚set 1事务。如果我们有任何选择可以这样做，请告诉我。感谢您的帮助。

Answer 1

如果删除set时发生任何错误 2我应该能够回滚第1组交易也是如此。让我知道，如果我们有这样的选择。感谢您的帮助。

然后，你为什么不这样做？

BEGIN TRY
   BEGIN TRANSACTION    -- Start the transaction

   DELETE SET 1(this will delete first set of table)
   DELETE SET 2 (will delete second set of table)

   -- If we reach here, success!
   COMMIT
END TRY
BEGIN CATCH
  -- Whoops, there was an error
  IF @@TRANCOUNT > 0
     ROLLBACK

  -- Raise an error with the details of the exception
  DECLARE @ErrMsg nvarchar(4000), @ErrSeverity int
  SELECT @ErrMsg = ERROR_MESSAGE(),
         @ErrSeverity = ERROR_SEVERITY()

  RAISERROR(@ErrMsg, @ErrSeverity, 1)
END CATCH

如果你的意思是删除表，就像删除表（即表，而不是内容）一样，你运气不好 - 不处理DDL。
