Sum values in last row for date format "hh24:mi"

Question

Hi,
I have a big problem creating a sum row with date data.
I created a sql view where the result looks like that:
SELECT category_name,
user_name,
b_mmyyyy,
b_1, ..., b_31
FROM view_category_user_booking
category_name, user_name, b_1, ..., b_31
category1, user1, 122008, 01:00, ..., 03:30
category2, user1, 122008, 02:00, ..., 01:00
category3, user1, 122008, 00:00, ..., 00:15My goal is to integrate a sum row at the end for the columns b_1 ... b_31
category_name, user_name, b_1, ..., b_31
category1, user1, 122008, 01:00, ..., 03:30
category2, user1, 122008, 02:00, ..., 01:00
category3, user1, 122008, 00:00, ..., 00:15
Sum, user1, 122008, 03:00, ..., 04:45I tried it like that:
select decode(grouping(category_name),1,'Summe',category_name),
sum(to_number(replace(b_1,':',','))) as b_1,
sum(to_number(replace(b_31,':',','))) as b_31
from category_user_booking
where user_name = 'user1'
and b_mmyyyy = '122008'
group by rollup(category_name)But the result isn't really successful
category_name, b_1, b_31
category1, 1, 3,3
category2, 2, 1
category3, 0, 0,15
Sum, 3, 4,45Is there somebody with an idea?
Thanks ahead,
Tobias

Answer 1

Hi Avinash,
the problem is not the grouping it is the date format.
Instead of a value like 5,4 > I want 05:40 or 1,75 > I want 02:15 in the sum value.
In my table all time values are saved in the format hh24:mi.
I don't know how to get that via a sql statement.
Output I want:
category_name, user_name, b_1, ..., b_31
category1, user1, 122008, 01:00, ..., 03:30
category2, user1, 122008, 02:00, ..., 01:00
category3, user1, 122008, 00:00, ..., 00:15
Sum, user1, 122008, 03:00, ..., 04:45Regards,
Tobias
