Thanks for posting the DDL. It does help if you include keys and constraints
with your CREATE TABLE statements and post some sample data abd required
results too. Here's my guess, hopefully it will give you a start even if it
isn't exactly what's required.
UPDATE child
SET newcode = 10
WHERE code = 5
AND EXISTS
(SELECT *
FROM child AS C
WHERE fk_parent_id = child.fk_parent_id
AND code > child.code
AND dt < child.dt) ;
