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.

First (if you haven't already done so) run the script shown above to generate the Doctor Who training database.

Using the tblAuthor and tblEpisode tables, create a stored procedure called spMoffats to list out the 32 episodes written by Steven Moffat in date order (with the most recent first):

The author and episode tables

The two tables from which you need to get data

Here is what the start of the output from running this stored procedure should look like:

Steven Moffat episodes

When you run the stored procedure, these are the first few rows that you should see.

 

Now amend your SQL so that it creates a different stored procedure called spRussell, listing out the 30 episodes penned by people called Russell:

Russell Davies episodes

The first few Russell Davies episodes (again shown with the most recently made coming first).

 

Wouldn't it be nice if you could introduce a parameter giving the name of the author for whom you want to list episodes, so you'd only need the one stored procedure ...

Optionally, save this revised query as Russell.sql, then close it down.
