Connect to a different port with SQL Server Management Studio

Hình ảnh
Microsoft's SQL Server Management Studio will connect by default to port 1433 and there's nowhere in the connect dialog to specify a different port from the default. To connect using a different port specify the servername, a comma, and then the port number as shown in this post. Connect using a different port using a comma The connection dialog in the SQL Server Management Studio client is shown in the screenshot below. Normally you would just type the server name into field but to specify a different port use a comma then the port number. The example screenshot above shows " 192.168.50.166\SQLSERVER2012 " as the instance name and "port" where the port would be. 192.168.50.166\SQLSERVER2012,1343 Then specify the login credentials, click the connect button, and assuming everything is correct it should then connect to the SQL Server.
