[英]Azure Application Insight Telemetry for On-Premises web app
[英]Accessing on-premises SQL database with web application hosted on Azure
我正在尝试从Azure托管的服务访问公司场所中存在的SQL数据库。 这是我尝试过的:
尝试使用Azure从数据库中获取记录时出现以下错误:
System.Data.SqlClient.SqlException (0x80131904): 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)

请帮忙。
Trusted_Connection必须为false。 您不能从Azure执行Windows身份验证。
