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.
If you haven't already got it set up in SQL server, restore the Historical Events database from the above folder.
Use a CASE statement to show the type for each event, using the following rules:
- If it's country 18, it must be United States
- If it's country 17, it must be UK
- Otherwise, it must be Somewhere else
The final results from running the query should look like this:
This query lists the events in date order
Save this query as Events by country type, then close it down.
