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.

Create the following query, using:

  • CONVERT to convert the date of each event to a more readable format; and
  • DATEDIFF to show the difference between each event's date and today in years

Your final output should look like this (sorted in reverse date order):

SQL exercise - Calculations using dates (image 1)

The DateDiff syntax is: DateDiff(year,EarlierDate,LaterDate)

Save this query as Am I really that old, then close it down.
