SQL | Archived exercise | Show events by decade
This exercise is provided to allow potential course delegates to choose the correct Wise Owl Microsoft training course, and may not be reproduced in whole or in part in any format without the prior written consent of Wise Owl.
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 to show the number of events for each decade:
The decade names have been chosen to ensure that they appear in the correct order in our query
You'll need a fairly long CASE statement to do this, and a fair bit of patience.
Save this query as Events by decade, then close it down.
