The aim of this exercise is to use a derived table to hold data before joining this another table. Start by selecting only events which end with a letter between N and Z.
Your query should return 300 results (including the CountryID column will allow us to join to the tblCountry table).
Now turn this select into a derived table called Second_Half_Derived. The layout will be something like this:
--Your select goes here
) AS Second_half_Derived
Now join tblCountry to the derived table as you would for a normal table:
This should return 230 results - scroll down for some happier events.
Optionally save this as Deriving results.sql and close it down.
