In SQL, can we always write an inner join statement as a main query and subquery or vice versa if we only want to find the intersection?
For example,
select * from gifts g where g.giftID in (select giftID from sentGifts);
can do a join and show the gifts sent in the sentGifts table, but it won't be able to show the sentTime because that is inside the subquery. But if all we care is to find the intersection, without caring what is being displayed, then we can always convert one to the other?
