我在我的應用程序中使用SqlHelper。如果使用SQL 服務器作爲數據庫,它工作正常。但它在Oracle中不起作用。如果Oracle是數據庫,我可以在VB.NET中使用SqlHelper類嗎?
它顯示:
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)
如何解決這個問題呢?
