Hm, I see two ways. The one is two separate SELECTs. Use the one to sum the one and use the result in the second.

The other one (what I not fully understand and never have used) is a subquery in the way

SELECT;
Cursor1.fieldXXX,;
(Select sum(blabla) from cursor2 where cursor2.field=cursor1.field) as nAggr;
from Cursor1
