Sql server begin附近的语法不正确，需要外部alter过程

我有一个脚本文件，它执行许多DDL操作-它都作为事务的一部分包含，但我在Alter Procedure的Begin语句中得到一个错误，因为Begin EXPECTION external附近的语法不正确-是否有任何方法将Alter过程作为事务脚本的一部分？以下是我的脚本：

需要帮忙吗？谢谢。

您不能对批进行“开始-尝试-开始-捕获”操作。您可以使用最后一批检查目录视图（例如sys.objects）来检查前面的所有步骤是否成功。然后，您可以决定批处理是否全部成功并提交或回滚

我想你应该这样写：

Begin transaction ....

...
Print N’any think that you like’;
Go

Alter procedure ....
...

---

首先，ALTER PROCEDURE必须是批处理中的唯一语句。旁注：您在TRY块的末尾回滚。那可能不是你想要的。
