Use COUNT, MAX and MIN to show statistics about the rows in the events table

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.

Before you can do this exercise, you'll need to download and unzip this file . Once you've done this:

Go into SQL Server Management Studio;
Open the SQL file you've just unzipped (you can press CTRL + O to do this); then
Execute this script.

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:

Statistics report

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.

You can unzip this file to see the answers to this exercise, although please remember this is for your personal use only.
