SQL | Table-valued functions exercise | An inline table-valued fn to show events for a 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.
The answer to the exercise will be included and explained if you attend the course listed below!

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:
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(
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:
What you should see for 1918.
Optionally, save all this as Annual events, then close down your query.
