Before you can do this exercise, you'll need to download and unzip this file (if you have any problems doing this, click here for help).

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!

SQL exercise - Scalar functions (image 1)

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.
