Before you can do this exercise, you'll need to download and unzip this file (if you have any problems doing this, click here for help).

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!
