If your Microsoft SQL Server database is running on a port that is different from the default port (1433), you can connect to Tableau Desktop by using the , format when typing the server name.
For example, suppose your SQL Server server name is "MyCo", and the port you are using is "8055". After you select the data source type, in the text box where you enter the SQL Server server name, type "MyCo, 8055."
