如何 select 一列具有其他列的最大值，以及另一个表中列的所有相应行？

Question

Two given tables:

Question: Select the activity with the highest cost and the names of the students that are registered in it.

Result should be: activity column(golf) and students column(mark antony). In this case there's just one student registered but I want to account for a case if there are more students registered.

I tried all kinds of solutions but I cant seem to get it right.

Any tips appreciated, thanks.

edit: I see Im getting downvoted, I didnt want to show what I tried because I think its way off the mark but here is some of it:

SELECT s.Student, a.Activity from Activities as a inner join Students as s 
ON a.ID = s.ID where a.Cost = (select max(a.Cost))

SELECT s.Student, a.cost, a.Activity from Activities as a inner join Students `as s ON a.ID = s.ID`
group by s.Student having a.cost = max(a.cost)

Answer 1

Following query works.

But please next time don't use images and you should also take a look at normalisation

CREATE TABLE activity ( `ID` INTEGER, `Activity` VARCHAR(8), `Cost` INTEGER ); INSERT INTO activity (`ID`, `Activity`, `Cost`) VALUES ('84', 'Swimming', '17'), ('84', 'Tennis', '36'), ('100', 'Squash', '40'), ('100', 'Swimming', '17'), ('182', 'Tennis', '36'), ('219', 'Golf', '47'), ('219', 'Swimming', '15'), ('219', 'Squash', '40');

 CREATE TABLE students ( `Student` VARCHAR(11), `ID` INTEGER ); INSERT INTO students (`Student`, `ID`) VALUES ('John Smith', '84'), ('Jane Bloggs', '100'), ('John Smith', '182'), ('Mark Antor', '219');

 SELECT Student,Activity FROM students s INNER JOIN ( SELECT id,Activity FROm activity WHERE Cost = (SELECT MAX(Cost) FROM activity)) a ON s.ID = a.id

 Student | Activity:--------- |:------- Mark Antor | Golf
