Question

I want to get values from a row with the largest certain value (in this example, the oldest member)

Select * from members where age=max(age)

Will this work?

And what will happen if there is more than 1 oldest members with the same age?

(I don’t have to worry about it because I use auto_increment, but I just got curious)

Thanks.

Answer 1

select * 
from members 
where age = (select max(age) as max_age from members);

If there are more than 1 member with the same maximum age, you will get multiple results. To select just one from that:

select * 
from members 
where age = (select max(age) as max_age from members);
limit 1

You can optionally add an order by if you favor any particular data over a random one.
