Hi Shaikshavali

By using a single query we cant eliminate duplicate rows i thnk

But u can use this subquery to delete duplicate rows

delete from table name where
salary in
(select salary from tablename
group by salary having count(*) > 1)


I thnk it vll work. but it vll delete all duplicate rows.
Corrections are welcome..
