SQL | Parameters and return values exercise | Creating a stored procedure parameter.
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. 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.
Create a stored procedure to list out the EventName, EventDate and Country fields (to do this you will need to join the tblEvent and tblCountry tables together using CountryID):
The first five rows that you might see.
Once you have done this, add a parameter to your stored procedure that will take in the country name of interest and use this to filter the rows displayed:
CREATE PROC ProcName
Try passing in different countries or parts of country names to change the number of events returned. Concatenating % or _ onto the parameter will return more results.
Using the letter S should return 94 results. Try the first letter of your name!
Optionally, save your query as Country events.sql, then close it down.
