The following example shows how to query the top ten sellers in ticket sales. The
WHERE clause defines a table subquery, and the result of the subquery consists of multiple
rows and one column.
Note The result of a table subquery can contain multiple rows and columns.
select firstname, lastname, cityname, max(qtysold) as maxsold
from users join sales on users.userid=sales.sellerid
where users.cityname not in(select venuecity from venue)
group by firstname, lastname, cityname
order by maxsold desc, cityname desc
limit 10;
