I need some help with some SQL pleeeaasseee....
I'm trying to do some summay work with some data using some of the
Oracle9i Analytic functions.
Here is the sample data:
SQL> select * from sum_test;
ID TODAY CODE VALUE
---------- --------- -------------------- ----------
1 02-FEB-03 A 100
1 02-FEB-03 A 200
1 02-FEB-03 B 50
1 03-FEB-03 A 50
1 03-FEB-03 B 25
1 05-FEB-03 A 725
1 05-FEB-03 C 125
1 02-FEB-03 A 100
1 03-FEB-03 A 100
2 02-FEB-03 A 100
2 03-FEB-03 A 100
2 04-FEB-03 B 100
and here is how I want the output to look:
Note that I want:
1. for the first day I want total by ID, tday (truncated date) and code. I
want the daily total in the VAL_TOTAL column
2. For each subsiquent day, I want that days total in val_total ADDED
to the previous total.
ID TDAY CODE VALUE VAL_TOTAL
---------- --------- -------------------- ---------- ----------
1 02-FEB-03 A 100 400
1 02-FEB-03 A 200 400
1 02-FEB-03 A 100 400
1 02-FEB-03 B 50 50
2 02-FEB-03 A 100 100
1 03-FEB-03 A 50 550
1 03-FEB-03 A 100 550
1 03-FEB-03 B 25 75
2 03-FEB-03 A 100 750
2 04-FEB-03 B 100 175
1 05-FEB-03 A 725 1275
1 05-FEB-03 C 125 125
Here is the query I'm trying:
select b.id, trunc(b.today) tday, b.code, b.value,
sum(a.val_total) over
(partition by b.id, trunc(b.today), b.code order by b.id,
trunc(b.today)
range between unbounded preceding and unbounded following) val_total
from
(
select id, trunc(today) today, code, sum(value) val_total
from sum_test
group by id, trunc(today), code
) a,
sum_test b
where a.id=b.id
and trunc(b.today)=a.today
and a.code=b.code
order by 2, 1
/
Results...
ID TDAY CODE VALUE VAL_TOTAL
---------- --------- -------------------- ---------- ----------
1 02-FEB-03 A 100 1200
1 02-FEB-03 A 200 1200
1 02-FEB-03 A 100 1200
1 02-FEB-03 B 50 50
2 02-FEB-03 A 100 100
1 03-FEB-03 A 50 300
1 03-FEB-03 A 100 300
1 03-FEB-03 B 25 25
2 03-FEB-03 A 100 100
2 04-FEB-03 B 100 100
1 05-FEB-03 A 725 725
1 05-FEB-03 C 125 125
Obviously not correct. I know I can do this with a self join to the table,
but I was hopeful that I could do it this way. Any ideas?
