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 got it set up in SQL server, restore the Historical Events database from the above folder.
Import the query called Extra text function. If you try running this query, it falls over - that's because the fnExtraText function doesn't yet exist!
This query should consider the extent to which the description of any event is longer than its short name
Create the function (and test that it works), then save the script to create it as CreatExtra text function.
