- Go into SQL Server Management Studio;
- Open the SQL file you've just unzipped (you can press CTRL + O to do this); then
- Execute this script.
This will generate the database that you'll need to use in order to do this exercise (note that the database and script are only to be used for exercises published on this website, and may not be reused or distributed in any form without the prior written permission of Wise Owl).
You need a minimum screen resolution of about 700 pixels width to see our exercises. This is because they contain diagrams and tables which would not be viewable easily on a mobile phone or small laptop. Please use a larger tablet, notebook or desktop computer, or change your screen resolution settings.
Create a query which lists out all of the events in the tblEvent table which happened after the last one for country 21 (International) took place. Here's the gist of what you need to do:
--SELECT
--list of fields
--FROM
--table of events
--WHERE
--Event date > (
--SELECT MAX(Event date)
--FROM table of events
--WHERE country id = 21
--)
-- ORDER BY
--Event date (descending)
You should get these 4 events:

There are only 4 events which happened after the last international one.
Save this query as Post-Int Notes, then close it down.
