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.
The Carnival database contains a table called tblMenu. This contains all of the menus for a website:
Each menu has an id number, and also contains within its record the id of its parent

This is what the results should look like!
Save this as Recursion using CTEs, then close it down.
