If you haven't already done so, run the script in the folder above to generate the Doctor Who database.
Right-click in a new query and use the designer to create a query linking these two tables:
Each episode is linked to the person who wrote it.
Add columns and filters to your query so that it shows who wrote the "special" episodes (there should be 13 listed out, of which the first few in alphabetical order are shown below):
The first few episodes containing the word special in the title.
For the filter, use the criteria LIKE '%special%'.
Now tidy up the generated query so that it looks more like proper SQL! Here's a suggestion:
-- the query, tidied up
SELECT
tblAuthor.AuthorName,
tblEpisode.Title,
tblEpisode.EpisodeType
FROM
tblAuthor
INNER JOIN tblEpisode ON
tblAuthor.AuthorId = tblEpisode.AuthorId
WHERE
tblEpisode.EpisodeType LIKE '%special%'
ORDER BY
tblEpisode.Title
Save this query as No joins necessary, then close it down.
