is it possible to make a group by on selected columns.
Ex:
code nom salary
1 A 10
2 B1 10
2 B2 30
If I type a group by
select code,
nom,
sum(salary)
from my_table
group by code, nom
the result is 3 lines.
But B1 and B2 are a mistake.
It's the same person.
So I want to print one line
Only Code 1 and Code 2.
It's possible to choose with Access (group by first), and what about Oracle.
Thanks for your Answer.

you said
"Thanks a lot for your message, but I want to see others colums.And with your code, only one column displayed."
the only column "code" can be displayed as it is included group by clause and other can not.
if u think logically , what u r talking is wrong.
u r summing the salary for particular codes and that code may be belongs to different rows
e.g.
rows are
1 A 10
2 B1 10
2 B2 30
and result are
1 10
2 40***what u want to see here
hope it helps!!!
