我在我的应用程序中使用 SqlHelper。如果使用 SQL Server 作为数据库,它可以正常工作。但它不适用于甲骨文。
表明:
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)
我该如何解决?
