Before you can do this exercise, you'll need to download and unzip this file (if you have any problems doing this, click here for help).

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 create a report called Quantity not quality, and within this create a dataset to show how many films each director has made:

Dataset using grouping

If you're not sure how to group in a dataset in SSRS, see the note below.

The easiest way to apply grouping is probably with the right mouse button: 

Group by tool

You can right-click on the top part of your query to apply grouping.

 

Now create a table in your report to show this data:

Table of directors and films

Your table doesn't have to look anything like this!

 

Create a calculated field using the SWITCH function giving a rating for each director using the following rules:

Number of films made Rating
1 One-hit wonder
2-3 Casual director
4-6 Experienced director
7+ Prolific

When you preview your report, you should see something like this:

Directors with ratings

See if you can find the only director whose rating is Prolific (it might not be a surprise when you do).

 

Close this report down.
