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 a query to show for each event the full date in the format shown below:

SQL exercise - Calculations using dates (image 1)

You will need to use DatePart or (better) DateName for this

Save this query as Full date, then close it down.

For an encore, and only if you have the time and energy, show that:

  • There weren't any events which took place on Friday 13th
  • The only event which took place on Thursday 13th was the instigation of the Public Record Act of July 1967
  • There were 3 events which took place on Saturday 13th, one of which wasn't a good day for Saddam Hussein

Write an essay explaining the significance of your findings in sociological terms!
