推荐答案

如果SQL服务器实例配置为允许远程访问，则完全相同。如果不是，那么无论您尝试什么，都无法做到。



所需要的只是连接字符串中正确的IP地址或域名而不是你的本地信息。您要连接的SQL Server实例的数据库管理员应该能够为您提供所需的所有信息，包括要使用的相应用户名和密码 - 远程连接从不使用集成安全性，因为它太不安全。

It's exactly the same, provided teh SQL server instance is configured to allow remote access. If it isn't, then you can't do it no matter what you try.

All you need is the right IP address or Domain Name in the connection string instead of your "local" information. The DB Admin for the SQL Server instance you want to connect to should be able to give you all the info you need, including the appropriate Username and password to use - remote connections never use Integrated security as it's too insecure.
