Code:
SELECT PNAME, WEIGHT FROM <TABLE-NAME> WHERE 1 = 1                             
GROUP BY PNAME, WEIGHT HAVING COUNT(WEIGHT)>1; 


Try this & let me know the results....

1=1 Is always true. It is required as you need to put a where condition in the query which has group by and having.

Please correct me if i am wrong.
