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 query using an inner join and table aliases to list out the non-European countries.  Because the syntax is so hard to remember, here's the middle bit of your query done for you:

SQL exercise - Basic joins (image 1)

The inner join, using table aliases

Your final result should look like this:

SQL exercise - Basic joins (image 2)

Your query should link the tblCountry and tblContinent tables

Save this query as Countries, and close it down.
