Analitic functions (problem with SELECT)

Question

Hi!
I've got a problem with analitic functions (I'm newbie in this topic).
I have a table gpw_notowania which have colums: not_open, not_minimum, not_maximum, not_close, not_volume, not_sp_id and not_date.
I need to receive from database the information: what is the open, minimum, maximum, close and sum of volume in every week? I have tried the code below but it tells me: ORA-01791 (marking not_date in ORDER clause).
Help me, please.
SELECT     distinct
     FIRST_VALUE(not_open)      OVER (partition by to_char(not_date,'WW') ORDER BY not_date)          as open,
     MIN(not_minimum)     OVER (partition by to_char(not_date,'WW') ORDER BY not_date)          as minimum,
     MAX(not_maximum)     OVER (partition by to_char(not_date,'WW') ORDER BY not_date)          as maximum,
     FIRST_VALUE(not_close)     OVER (partition by to_char(not_date,'WW') ORDER BY not_date DESC)     as close,
     sum(not_volume)          OVER (partition by to_char(not_date,'WW'))                    as volume
FROM     gpw_notowania
WHERE     not_sp_id = 80
ORDER BY not_date;

This is an interesting question.
create table SortWithDistinct(Val1,Val2,sortKey,SubSortKey) as
select 1,3,10,1 from dual union all
select 1,3,10,1 from dual union all
select 1,3,10,1 from dual union all
select 2,4,30,2 from dual union all
select 2,4,30,2 from dual union all
select 3,5,20,1 from dual union all
select 3,5,20,1 from dual union all
select 4,6,10,3 from dual union all
select 5,5,10,2 from dual union all
select 5,5,10,2 from dual union all
select 9,9,10,4 from dual union all
select 6,4,20,2 from dual union all
select 6,4,20,2 from dual union all
select 7,3,30,1 from dual union all
select 7,3,30,1 from dual;
select distinct Val1,Val2
  from SortWithDistinct
order by sortKey,SubSortKey;
ORA-01791: not a SELECTed expressionIt is one way that we use "group by".
for instance
select Val1,Val2
  from SortWithDistinct
group by Val1,Val2
order by max(sortKey),max(SubSortKey);
Val1  Val2
   1     3
   5     5
   4     6
   9     9
   3     5
   6     4
   7     3
   2     4It is one way that we use "Inline View".
for instance
select Val1,Val2
from (select distinct Val1,Val2,sortKey,SubSortKey
from SortWithDistinct)
order by sortKey,SubSortKey;
Furthermore, we may use below alternative solution which uses "dense_Rank".
select Val1,Val2
from (select distinct Val1,Val2,
      dense_Rank() over(order by sortKey,SubSortKey) as willSortKey
        from SortWithDistinct)
order by willSortKey;Because "distinct" works after OLAP.
for instance
SQL> select distinct ColA,ColB,Row_Number() over(order by 1) as Rank
  2  from (select 1 as ColA,1 as ColB from dual
  3  union all select 1,1 from dual
  4  union all select 1,1 from dual
  5  union all select 1,1 from dual
  6  union all select 2,2 from dual
  7  union all select 2,2 from dual
  8  union all select 2,2 from dual)
  9  order by 1,2,3;
ColA  ColB  Rank
   1     1     1
   1     1     2
   1     1     3
   1     1     4
   2     2     5
   2     2     6
