Do you mean, as following?

SELE ;
    a.inv_cd, ;
    sum(a.balance+b.balance) balance,;
    sum(a.interest+b.interest) interest,;
    discount,;
    premium;
from table_A a , table_b b;
where a.inv_cd=b.inv_cd;
group by 1

"Group by 1" assuming discount and premium do not change across records for the very same inv_cd, "group by 1,4,5" otherwise.
