Oracle 10g Rows to column

Question

Hi
I have folowing scenario. I am getting the result with some query like below :
STATE      DAY     AVG
NY        02/02     5
NY        02/03     10
NY        02/04     20
NY        02/05     15
IL        02/02     23
IL        02/03     34
IL        02/04     29
IL        02/05     9
FL        02/02     15
FL        02/03     8
FL        02/04     9
FL        02/05     10
and so on..Now I want to convert it from rows to column, but still want to keep STATE column group by :
so the result would be :
STATE   02/02   02/03   02/04   02/05
NY        5      10       20    15
IL        23     34       29    9
FL        15     8        9     10
and so on...I tried using pivot function, but it didnt work. is it even possible? or I will have to do it in code (.net c#) side.
Thanks
