SQL | Archived exercise | Subquery using historical events
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.
The answer to the exercise will be included and explained if you attend the relevant Wise Owl course (sadly, only in the UK for now).
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/subquery showing all of the events which happened after the last European Union event (or if you prefer, which happened after any of the European Union events). Here's what your results should look like:
Only 7 events have happened since the last EU event
Save this query as Events after EU, and close it down.
