hi sam

this is very easy one.

Try this qry:

delete from tablename where rowno=4 and name='suresh' ;

OR Duplicate Rows Oracle Table

DELETE FROM our_table
WHERE rowid not in
(SELECT MIN(rowid)
FROM our_table
GROUP BY column1, column2, column3... ;

Here column1, column2, column3 constitute the identifying key for each record.
