Even a small example of what you wanted would have worked.
Anyway, lets see if I can got your problem.
There are two records in your table emp:
id | name | salary
-------------------------
21 | scott | 2000
31 | greg | 3000
So you want to copy all the data from 'scott' row on to 'greg' row, but keep
the id (id obviously being your unique identifier).
UPDATE emp
SET (salary, name) = ( (select salary from emp where id = 21 ),
(select name from emp where id = 21) )
where id = 31;
HTH,
