You need a minimum screen resolution of about 700 pixels width to see our exercises.

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.

Create a procedure called spSummariseEpisodes to show:

  • the 3 most frequently-appearing companions; then separately
  • the 3 most frequently-appearing enemies.

Here's what you should see when you run this stored procedure:

Top 3 episodes by companion and enemy

Not many surprises here for the Doctor Who aficionado.

 

Change your script to alter your procedure so that it shows the 5 least-frequently appearing companions, and 5 least-frequently appearing enemies.

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