Query to total columns

Question

Hello,
Using Oracle 11g R2. I'm trying to present data in the following format. I've come up with the query below, but I don't think it's right.
COL1
COL2
COL3
NVL(COL4,SUM(COL4))
NVL(COL5,SUM(COL5))
NVL(COL4-COL5,SUM(COL4-COL5))

create table testrollupRh (col1 number, col2 number, col3 date, col4 number, col5 number)
insert into testrolluprh values (1, 10, sysdate - 10, 40, 50)
insert into testrolluprh values (1, 20, sysdate - 9, 80, 20)
insert into testrolluprh values (1, 30, sysdate - 8, 25, 60)
insert into testrolluprh values (2, 40, sysdate - 7, 90, 10)
insert into testrolluprh values (2, 50, sysdate - 6, 85, 50)
select col1,
         col2,
         col3,
         NVL(col4, SUM(col4)),
         NVL(col5, SUM(col5)),
         NVL(col4 - col5, SUM(col4 - col5))
from  testrolluprh
where col1 is not null
and col2 is not null
and col3 is not null
and col4 is not null
and col5 is not null
group by rollup ((col1), (col1, col2, col3, col4, col5))
Any help is appreciated.

Hi,
I don't see any problems with your code.
You should have an ORDER BY clause, of course.  Almost all queries need an ORDER BY clause, but that's often omitted in this forum.
If you want to put labels, such as 'Total 1' and 'Grand Total' on the super-aggregate rows, you can use CASE and GROUPING, like this:
SELECT    CASE
              WHEN  GROUPING (col2) = 0  THEN  TO_CHAR (col1)
              WHEN  GROUPING (col1) = 0  THEN  '   Total ' || col1
                                         ELSE  '     Grand Total'
          END                                    AS out1,
          col2,
          col3,
          NVL (col4,        SUM (col4))          AS out4,
          NVL (col5,        SUM (col5))          AS out5,
          NVL (col4 - col5, SUM (col4 - col5))   AS out6
FROM      testrolluprh
WHERE     col1   IS NOT NULL
AND       col2   IS NOT NULL
AND       col3   IS NOT NULL
AND       col4   IS NOT NULL
AND       col5   IS NOT NULL
GROUP BY  ROLLUP ( (col1)
                 , (col1, col2, col3, col4, col5)
ORDER BY  col1, col3
Output:
OUT1                   COL2 COL3              OUT4       OUT5       OUT6
1                        10 29-Oct-2013         40         50        -10
1                        20 30-Oct-2013         80         20         60
1                        30 31-Oct-2013         25         60        -35
   Total 1                                     145        130         15
2                        40 01-Nov-2013         90         10         80
2                        50 02-Nov-2013         85         50         35
   Total 2                                     175         60        115
     Grand Total                               320        190        130
