Running Total Query in Oracle

8i, Standard, no Analytic functions available....

I need to calculate a running total column which would be the sum of a column for all preceding rows including the current row. for example, if my data was:

ID VAL
1   100
2   100
3   50
4  25

and I was doing a running total on VAL, Ordered By ID, then my result set would be
ID VAL RUNNING_TOTAL
1   100   100
2   100   200
3   50    250
4   25    275

etc, etc.

Any ideas?

Given a table called exp_test, try something like this:

select      it1.id
,            it1.val
,            (select      sum(it2.val)
             from      exp_test it2
             where      it2.id <= it1.id)            
from exp_test it1

How about:

select id, val, (select sum(val) from mytable t2 where t2.id <= t1.id) running_total
from mytable t1
order by id;
