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 listing out the event date and event name for all German events (ie for all events where the CountryId equals 7):

SQL exercise - Setting criteria using WHERE (image 1)

There are 6 events in our database which took place in Germany

Now amend your WHERE clause so that you only see events which took place in Germany in the 1940s (ie where the EventDate column lies between 1st January 1940 and 31st December 1949):

SQL exercise - Setting criteria using WHERE (image 2)

This should take you down to just these 2 events

Save this query as German events in 40s.sql, and close it down.
