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.

First choose to create a view in the HistoricalEvents database:

You can right-click to create a new view

Design a view to show all of the events occurring in Africa, in date order.  As a clue, here is what the top half of the view designer should look like:

SQL exercise - Views (image 2)

You'll need to include these 3 tables

Run your view - it should return 3 events only:

Not much happens in Africa? Or more likely, the database is hopelessly biased

Save this view as vwAfrica, then close it down.

Right-click on the view to script it to a new window.

Change the script in two ways:

  • Firstly, so that it creates a new view called vwAfricaAsia, rather than altering the existing one; and
  • Secondly, so that it shows the events in Africa or Asia

Run this script, then close down its window. 

Refresh your list of views, and run your new vwAfricaAsia view to show that it returns 23 events.
