SQL | Archived exercise | Link training tables with 2 parameters
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.
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.
If you haven't already done so, run the stored procedure in the above folder to generate a database of training courses and delegates. This exercise uses the following tables:
The five tables you need to join together!
Create a stored procedure called spListDelegates which displays, for a given company name and course name extract, the people who are attending courses. If you leave either of the two parameters out, your stored procedure should show all rows for that parameter.
Here are some ways in which you could test your stored procedure:
These calls to your procedure should return 1 (if you're looking for an exact company name match), 20 and 124 delegates respectively.
Optionally, save the query to generate your stored procedure as Delegates for course and company.sql, then close it down.
