A network-related or instance-specific error occurred while establishing a connection to SQL Server. The server was not found or was not accessible. Verify that the instance name is correct and that SQL Server is configured to allow remote connections. (provider: Named Pipes Provider, error: 40 - Could not open a connection to SQL Server) (Microsoft SQL Server, Error: 2)
我想使用 SQL Server 身份验证，但我不确定如何使用用户名和密码设置帐户。帮助，我是新手；我只有 MySQL 的经验，这似乎要复杂得多。
