- 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.
Create a query which uses two separate SELECT statements to show the first and last 2 events in date order from the tblEvent table:

Run two SELECT commands one after the other to get these results.
Now redirect the output of this query to text, rather than to grid, to get something like this when you run it:

The same results, but in text form.
If you think this looks messy (and it does), try adding the command SET NOCOUNT ON to the beginning of your query, to suppress the row number messages.
Save this query as How times change, then close it down.
