I got it working using a correlated subquery like this:
update x a
set a.id2 = (
select b.id2
from x b
where b.id2 <> 0
and b.id1 = a.id1
)
where a.id2 = 0;

Hi,
I have table x with 2 columns:
ID1 ID2
---- ----
1 0
1 5
2 0
2 10
I want to update ID2, set the 0s to the other value
for the same ID1. So, i would have:
ID1 ID2
---- ----
1 5
1 5
2 10
2 10
Whats the best way to do this?
Thanks.
