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).
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:
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:
The first few events in the list.
Save this query as Shortest events, then close it down.

Query_Sol. for MySQL users
-- in MySQL, LEN() function is different as LENGTH()
-- used 'char_length' to avoid pound symbol bytes count
SELECT EventName, CHAR_LENGTH(EventName) AS 'Length of name'
ORDER BY CHAR_LENGTH(EventName);
