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 done so, run the script in the above folder to generate the HistoricalEvents database.

Create a query to show all events which satisfy either (or both!) of the following criteria:

  • The event took place in any country apart from 17 (the UK) in the year 2001; or
  • The event took place in any of countries 3, 5 or 7 (Canada, the EU or Germany, as it happens), but doesn't have a U in its name

Use the IN keyword for the second criteria.

Your query should show the following 10 records:

The events are shown here in date order

Save this query as Lots of criteria.sql, then close it down.
