SQL | Archived exercise | Simple stored procedure showing top 10 websites
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 relevant Wise Owl course (sadly, only in the UK for now).
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 the world's leading websites. This database contains a table of websites called tblWebsite:
Rankings are from Alexa, a company which analyses the popularity of websites
Create a query which lists out the top 10 websites in the UK (ie ordered by AlexaRankUk, where the AlexaRankUk column is not null):
Don't forget to use the UK Alexa ranking when ordering
Now create a stored procedure from this query called spListTopWebsites. Execute your stored procedure to check that it gives the same answer.
Alter your stored procedure (change the word CREATE to ALTER) so that it lists out the top 5 websites, not the top 10.
Optionally, save the code to generate the stored procedure as spListTopWebsites.sql, then close it down.
