I think SQL does a fine job of summing nulls.
create table qtemp.mytable (
mychar char(5),
mydec dec(15, 5));
insert into qtemp.mytable (mychar, mydec) values ('A', 2);
insert into qtemp.mytable (mychar) values('B');
insert into qtemp.mytable (mychar, mydec) values ('C', 4);
select * from qtemp.mytable;
MYCHAR MYDEC
A 2.00000
B -
C 4.00000
select sum(mydec) as total from qtemp.mytable;
TOTAL
6.00000
