Tell me the age of the members of the club "Tennis Club".
select t3.age from club as t1 join member_of_club as t2 on t1.clubid = t2.clubid join student as t3 on t2.stuid = t3.stuid where t1.clubname = "Tennis Club"
How about that of the club "Bootup Baltimore"?
select t3.age from club as t1 join member_of_club as t2 on t1.clubid = t2.clubid join student as t3 on t2.stuid = t3.stuid where t1.clubname = "Bootup Baltimore"
Can you show me the average number?
select avg(t3.age) from club as t1 join member_of_club as t2 on t1.clubid = t2.clubid join student as t3 on t2.stuid = t3.stuid where t1.clubname = "Bootup Baltimore"
