Adding count total column .

Question

Hi,
I'm dealing with 9.2.0.8 so some restrictions may apply :).
here is the case
SQL> create table t (id number) ;
Table created.
SQL> insert into t values(1);
1 row created.
SQL> insert into t values(1);
1 row created.
SQL> insert into t values(1);
1 row created.
SQL> insert into t values(2);
1 row created.
SQL> commit;
Commit complete.
SQL> select * from t;
        ID
         1
         1
         1
         2
SQL> select count(*), id , ratio_to_report(count(*)) over () *100 pct , count(*) over ()  from t group by id;
  COUNT(*)         ID        PCT COUNT(*)OVER()
         3          1         75              2
         1          2         25              2
but I need last column as all rows in table so should be
SQL> select count(*), id , ratio_to_report(count(*)) over () *100 pct , count(*) over ()  from t group by id;
  COUNT(*)         ID        PCT COUNT(*)OVER()
         3          1         75              4
         1          2         25              4
how to rewrite that, ratio_to_report gives percentage which is quite good but need all rows .Regards

Hi,
Do you need this?
select count(*)
      ,id
      ,ratio_to_report(count(*)) over () *100   as pct
      ,sum(count(*)) over()  
  from t
group by id;
