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 websites.  This exercise uses the following two tables:

SQL exercise - Parameters and return values (image 1)

Each website belongs to a category

Create a stored procedure called spWebsitesByCategory which takes a single parameter - the name of a category - and displays all of the websites which belong to that category.  For example:

SQL exercise - Parameters and return values (image 2)

You could execute your stored procedure to show all of the websites in the search engine category, for example

The above example would show the following output:

SQL exercise - Parameters and return values (image 3)

The start of the list of search engine websites

Optionally, save the query to generate your stored procedure as Websites for chosen category.sql, then close it down.
