Just guessing without more detailed information, but are the tables
related one-to-many using foreign keys? If so, when defining the foreign
key you can set the delete to cascade whenever a "master" row is deleted:
alter table foo
add constraint foo_fk foreign key [...]
on delete cascade;
...or something like that.
