Answer 1

Note: The STUFF function simply removes the leading / from the string returned.

SELECT t1.id, 
       STUFF((SELECT '/' + t2.name
                FROM YourTable t2
                WHERE t1.id = t2.id
                ORDER BY t2.name
                FOR XML PATH('')),1,1,'') AS Name
    FROM YourTable t1
    GROUP BY t1.id
