Run two SELECT queries to show the first and last events

This exercise is provided to allow potential course delegates to choose the correct Wise Owl Microsoft training course, and may not be reproduced in whole or in part in any format without the prior written consent of Wise Owl.

Before you can do this exercise, you'll need to download and unzip this file . Once you've done this:

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).

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

Combining queries

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:

Results to text

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.

You can unzip this file to see the answers to this exercise, although please remember this is for your personal use only.
