SQL | Stored procedures exercise | Basic stored procedure to show countries in Asia
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.
The answer to the exercise will be included and explained if you attend the course listed below!
- 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).
You need a minimum screen resolution of about 700 pixels width to see our exercises.

Create a stored procedure called uspCountriesAsia to list out all the countries with ContinentId equal to 1, in alphabetical order:
The first few countries your procedure should show when you run it.
As a reminder, the syntax of a basic stored procedure is:
CREATE PROC NameOfProcedure
-- now do something
If you've got this working, modify the text of your query to create a different procedure called uspCountriesEurope which lists all the countries in continent id number 3, and check that this works.
Close down all your SQL Server Management Studio windows. Find the procedure called uspCountriesAsia in Object Explorer, and choose to modify it. Change the procedure so that it lists out the CountryId too:
The output from your procedure now includes the country id.
Optionally save your query as Basic procedures.sql, then close it down.
