SQL | Archived exercise | List all films without actors, and vv
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 relevant Wise Owl course (sadly, only in the UK for now).
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.
If you haven't already done so, run the script in the above folder to generate the Movies database.
Write a query to show the 96 films for which no actors exist:
The first few actorless films, in alphabetical order
You'll need to create a join from the film table to the cast table, and another join from the cast table to the actor table.
If you have time, write another query to show that there are no actors who do not appear in any films in the database.
Save your query - somewhat pretentiously - as Filmes sans acteurs, then close it down.
