Before you can do this exercise, you'll need to download and unzip this file (if you have any problems doing this, click here for help). Once you've done this:
  1. Go into SQL Server Management Studio;
  2. Open the SQL file you've just unzipped (you can press CTRL + O to do this); then
  3. 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).

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.

To do this exercise, you'll need to know that you can use the LEN function to work out how many characters there are in a bit of text.  For example, this query:

-- how big is Wise Owl?

SELECT LEN('Wise Owl')

Would return this result:

Length of Wise Owl

There are 8 characters in this text string, including the space.


Use this nugget of information to create a query listing out each event with the length of its name, with the "shortest event" first:

Shortest events

The first few events in the list.


Save this query as Shortest events, then close it down.
