First, let me say that you cannot delete from more than one table with a single statement.

Second, and I'm not trying to be cute:

ALTER TABLE a ADD CONSTRAINT a_pk PRIMARY KEY (deptno);

ALTER TABLE b ADD CONSTRAINT b_a_fk FOREIGN KEY (deptno) REFERENCES a (deptno) ON DELETE CASCADE;

DELETE a WHERE deptno = 1234;
