在执行我传入的存储过程名时也进行循环。我还没有，我甚至不认为我已经测试过这种方法，尽管它似乎几乎可以肯定它确实有效，但我对它的工作方式非常好奇。TVF中的动态SQL听起来确实很有趣，确实值得研究。因此，我今天尝试使用动态SQL和使用集成身份验证的SQL CLR处理这个远程SP调用，并立即遇到了这个问题：Kerberos协议转换和受约束的委派@tbone是的，无论您是否使用模拟，这都是一个问题。旧的Kerberos双跳限制。现在，如果该过程是通过SQL代理自动完成的，那么登录将直接登录到SQL Server机器，因此您不应该有Kerberos问题。或者，如果您不使用模拟，而是让流程使用MSSQLSERVER服务帐户的安全上下文，那么也应该可以使用。但这是另一个问题，对吗？授权也将解决这个问题。我链接到一篇文章，该文章展示了如何在SQLCLR文章的阶梯中进行设置。
