Solution heavily depends on the relation of products and othertable.
If ordercode at most has a single match with ordercode from othertable,
then a simple left join and a coalesce() or CASE in the select list will do
( SELECT p.ordercode, p.descr, CASE WHEN t.codes is NULL THEN
p.ordercode ELSE t.ordercode | 512
from products p left join othertable t on p.ordercode = t.ordercode
WHERE........ ;)
IF othertable has several matching rows you might need to applay an
aggregator adding in all the bits for codes....
However, your update statement seems to imply something along the first
case......
