Using a table named tmpa with the following values:

K VAL
- ----------

A          1
B          2
C          3
D         10
E         20

Use the following query:

  select b.key, sum(a.val)
  from tmpa a, tmpa b
  where a.key <= b.key
  group by b.key

to produce:

K SUM(A.VAL)
- ----------

A          1
B          3
C          6
D         16
E         36
