Not sure why you have the second join to the history table. If each upload has a unique user and a unique history row, then user_id in the history table is useless information for this query. The second history join is giving you the redundant rows.

Try and avoid using DISTINCT and its variations. It requires the server to do more work and therefore slow down your query.


SQL
SELECT 
    US.name, 
    US.address, 
    UP.file_path, 
    UP.picture_path, 
    HS.location
FROM 
    [user] US
LEFT JOIN 
   uploads UP 
   ON (US.user_id = UP.user_id)
LEFT JOIN 
   history HS 
   ON (US.upload_id =  HS.upload_id)
WHERE 
   US.user_id = 5
ORDER BY 
   US.user_id
