Partition by, rank over .... ?

Question

Hi , my dear sqlplsql expert gurus. Its real pleasure to learn from you.
I doubt my problem will be difficult to you so i cant' wait to see your advices. :)
I have this query:
SQL> SELECT   COUNT (*), states
  2      FROM my_case
  3     WHERE states IN (1, 2)
  4  GROUP BY states
  5  ORDER BY 1 DESC;
  COUNT(*)      STATES
   1624307          1
     12547          2Is there some way to include the SUM function and get the output similiar to this :
SQL> SELECT   COUNT (*), states
  2      FROM my_case
  3     WHERE states IN (1, 2)
  4  GROUP BY states
  5  ORDER BY 1 DESC;
  COUNT(*)      STATES
   1624307          1
     12547          2
    SUM
  1636854

Hi,
You can use ROLLUP to get totals, like this:
SELECT       COUNT (*)
,       NVL ( TO_CHAR (deptno)
           , 'Total'
           )          AS dept
FROM       scott.emp
WHERE       deptno     IN (10, 20)
GROUP BY  ROLLUP (deptno)
;Output:
. COUNT(*) DEPT
         3 10
         5 20
         8 TotalIs output like:
    SUM
  1636854
an important part of this problem?
If so, does the above need to be 4 separate rows in the result set, or would a single row (with some embedded CHR(13) characters to start new lines) be good enough?
