Write a query which lists out countries which have more than 8 events, using a correlated subquery rather than HAVING

That is: list the names of countries from the countries table where for each country the number of events matching the country's id is more than 8.

If you list the countries in alphabetical order, you should get:

Countries with events

Although your query should be easy to read, one disadvantage is that you can't see how many events there were for each country.

 

Save this query as Eventful countries, then close it down.
