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.
This will generate the database that you'll need to use in order to do this exercise (note that the database and script are only to be used for exercises published on this website, and may not be reused or distributed in any form without the prior written permission of Wise Owl).
Create a query to list out the following statistics from the table of events:
You'll need to use the COUNT, MAX and MIN functions respectively.
Your query won't need a GROUP BY, as you're not grouping by anything - just a SELECT and a FROM.
Save this query as Statto, then close it down.
