넵 `not in`, `not between`, `is not null` 같은 연산자들은 특정 범위에 접근하는 것이 아니기 때문에 인덱스 활용을 못하는 것으로 알고 있습니당

맞습니다 해당 내용은 `dept_no = 'd003' or dept_no = 'd004' .. ` 으로도 작성할 수 있습니다 그렇지만 보통 사용되는 쿼리에서 in -> or 변환은 가능하나 or -> in 변환은 안되는 것으로 알고 있어요

사용 목적은 다양하겠지만, explain을 사용하면 해당 쿼리를 어떻게 실행할지에 대한 정보를 확인할 수 있는데요! 동일한 결과를 반환하는 두 개의 쿼리가 있을 때 해당 정보를 통해 더 좋은 성능을 내는 쿼리를 선택할 수 있겠죠 ??
