连接到SQL Server时端口号无效

Question

When connecting to SQL Server, it shows the port number is not valid. I set up TCP/IP,it still shows Port number is not correct while connecting to sql server:

Answer 1

If I read https://msdn.microsoft.com/en-us/library/ms378428(v=sql.110).aspx correctly, it says the URL should be jdbc:sqlserver://localhost:1433 or else jdbc:sqlserver://localhost\\friend

Assuming the instance Friend is on port 1433.
