This exercise is provided to allow potential course delegates to choose the correct Wise Owl Microsoft training course, and may not be reproduced in whole or in part in any format without the prior written consent of Wise Owl.
The answer to the exercise will be included and explained if you attend the relevant Wise Owl course (sadly, only in the UK for now).
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.
Create a view using the view designer which will be a repeat of one we did in an earlier exercise. The view should show for each country the number of events occurring since 1990, but exclude countries with less than 5 events:
What you should see when you run your view
Save this view as vwEventsByCountry.
Now amend your view by scripting it to a new window
Your SQL will look fairly messy
Edit this procedure so that it is a bit easier to read, then execute it:
A suggestion for the final answer
Have a look at the design of your view - it should have changed!
