How does the Administrator check the correct SQL server database Port number? (Community Edition)

The correct database port number is necessary to set up the integration. 

To find out which port the database is configured on, execute the following query with SQL server management studio:

SELECT DISTINCT 
 local_tcp_port 
FROM sys.dm_exec_connections 
WHERE local_tcp_port IS NOT NULL

Click "execute", and the port that your SQL Server is listening on will be displayed as below.
