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). Once you've done this:
  1. Go into SQL Server Management Studio;
  2. Open the SQL file you've just unzipped (you can press CTRL + O to do this); then
  3. 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).

The aim of this exercise is to create a table-valued function to show events for any given year.  For example, you should be able to run this query:

SELECT

*

FROM

dbo.fnEventsForYear(1918) AS e

To show the events which took place in 1918:

Events in 1918

The events which take place in this year.

To help you, here is the syntax of a table-valued function:

CREATE FUNCTION FunctionName(

@Parameter datatype

)

RETURNS TABLE

AS

RETURN

SELECT ...

If you get this working, create another query which joins to the results of your table-valued function to show the category and country for each event in a given year:

Country and category

What you should see for 1918.

Optionally, save all this as Annual events, then close down your query.
