推荐答案

在这里，您有许多数据库服务器的连接字符串示例: http://www.connectionstrings.com/ [ ^ ].选择合适的一个.
但是请注意以下内容:
-提供者不太可能会打开从Internet可以访问数据库连接所需的tcp端口.很可能会为您提供可从内部"使用的连接字符串，并且您将无法通过该提供程序的边界-双向.
-集成身份验证方法仅在域或本地环境中不能通过Internet使用，因此您将需要用户名和密码

Here you have a lot of connection string samples for several database servers: http://www.connectionstrings.com/[^]. Choose the proper one.
But be aware of followings:
- It is unlikely, that a provider will keep open the tcp ports necessary for a database connection to be accessible from internet. It is more likely, that you will be provided the connection string you can use from "inside", and you will not be able to pass the boundaries of that provider - in neither direction.
- Integrated authentication methods can not be used over internet, only in domain or local environment, thus you will need a username and a password
