Create a table-valued function to list events for a given year

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).

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:

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

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:
