Oracle Delete Rows Matching On Multiple Values

Question

I want to do something like:

DELETE FROM student WHERE
student.course, student.major IN
(SELECT schedule.course, schedule.major FROM schedule)

Answer 1

You could also use the EXISTS clause:

DELETE FROM student WHERE
EXISTS
(
  SELECT 1 FROM schedule 
  WHERE schedule.course=student.course 
  AND schedule.major=student.major
)
