Mahamad A. Kanouté :
I have followed this link and several others where they showed how to go in a particular direction but not the other.
My original query written with JOINs:
SELECT DISTINCT * FROM membership
JOIN rental ON membership.MEM_NUM = rental.MEM_NUM
JOIN detailrental ON rental.RENT_NUM = detailrental.RENT_NUM
WHERE DETAIL_DUEDATE < DETAIL_RETURNDATE
GROUP BY membership.MEM_NUM;
I have tried to use INs here: (It doesn't not work)
SELECT DISTINCT * FROM membership
WHERE membership.MEM_NUM IN (SELECT rental.MEM_NUM FROM rental)
WHERE rental.RENT_NUM IN (SELECT detailrental.RENT_NUM FROM detailrental)
WHERE DETAIL_DUEDATE < DETAIL_RETURNDATE;
ERD:
My overall purpose is to answer this question while using the IN clause: Lists all details of members who returned their rented DVDs late
Here's the database file: https://pastebin.com/wBjmHcfX

I don't know why you try do do this.
Because i don't think that will be faster.
I' added also the GROUP By Clause.
SELECT DISTINCT * FROM membership
WHERE membership.MEM_NUM IN (SELECT rental.MEM_NUM
FROM rental
WHERE rental.RENT_NUM IN (SELECT detailrental.RENT_NUM
FROM detailrental
WHERE DETAIL_DUEDATE < DETAIL_RETURNDATE)
)
GROUP BY membership.MEM_NUM;
