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.

If you haven't already done so, run the SQL script in the above folder (copying and commercial use prohibited) to generate a database called MAM.

Create a data model similar to the one below (it doesn't matter what fields you hide from client tools, as long as you include these tables):

Data model

The tables to include, allowing us to link quadrants to animals.

Now create this pivot table showing the number of legs for each animal across the top, and the quadrant name down the left-hand side:

Quadruped percentages

See below for notes.

This pivot tables shows:

  • The total quantity sold for each cell's query context; and
  • The percentage this constitutes of the total for quadrupeds.

Use the CALCULATE function for the denominator for the ratio.

If you've got this working, add another calculated field which shows the percentage of the total for all leg types, using CALCULATE and ALL:

Percent of total for all leg types

Reassuringly, the total on the right is 100%. Quadrupeds constitute just over 54% of total sales.

When you've finished, save this query as Four legs good, and close it down.
