- Go into SQL Server Management Studio;
- Open the SQL file you've just unzipped (you can press CTRL + O to do this); then
- Execute this script.
This will generate the database that you'll need to use in order to do this exercise (note that the database and script are only to be used for exercises published on this website, and may not be reused or distributed in any form without the prior written permission of Wise Owl).
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.
First create a query showing events which took place in your year of birth, neatly formatted.
Rather than showing events between the 1st January and 31st December in the year in question, it's easier just to show events where the year function returns the right number.
This should give you something like this:
These are the events for 1978, the second-best year to be born in.
Amend your query so that it shows the event date neatly formatted:
- Once using the FORMAT function; and
- Once using the CONVERT function.
Here's what the final results should look like (don't forget, your events will be different):
You could of course cheat, and do the last two columns using the same expression ...
Save this query as The Great Owl sees all, and close it down.
