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.
First (if you haven't already done so) run the script shown above to generate the Doctor Who training database.
Create a procedure called spEpisodesSorted which takes two parameters:
|Parameter||What it does||Default value|
|@SortColumn||The name of the column to sort by||EpisodeId|
|@SortOrder||The order to sort by (ASC or DESC)||ASC|
Declare and build up a string variable called @sql which contains a SELECT command based on the value of these two parameters, and execute it like this:
-- run command contained in variable
You should now be able to list the Doctor Who episodes in different orders! For example:
-- show episodes in default order
-- show episodes in reverse title order
spEpisodesSorted 'Title', 'DESC'
When you've got this working, optionally save the query as Allsorts.sql, then close it down.
