PowerPivot | The CALCULATE function exercise | Use CALCULATE to show the value of sales for watery habitats
This exercise is provided to allow potential course delegates to choose the correct Wise Owl Microsoft training course, and may not be reproduced in whole or in part in any format without the prior written consent of Wise Owl.
You can learn how to do this exercise on the relevant Wise Owl classroom training course (sadly for the moment only in the UK).
- Go into SQL Server Management Studio;
- Open the SQL file you've just unzipped (you can press CTRL + O to do this); then
- Execute this script.
This will generate the database that you'll need to use in order to do this exercise (note that the database and script are only to be used for exercises published on this website, and may not be reused or distributed in any form without the prior written permission of Wise Owl).
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.
The aim of this exercise is to show the percentage of the values of sales for each region attributable to watery habitats. Read on!
First import the following tables into a PowerPivot data model in a new workbook:
The tables that you'll need to import for this exercise.
In the Purchase table, create a measure to calculate the total value of sales for habitats with id numbers 3 and 4 (corresponding to fresh and salt water respectively).
You'll need to use the CALCULATE function, the SUMX function to sum (price * quantity) and the double pipe characters ( || ) to denote "or".
Use this measure to show total watery sales by shopping centre type:
You should format your numbers to look nice!
Now create another (similar) measure called Vegetation, showing the total value of sales for vegetative habitats (id numbers 1 and 2, for grasslands and forest respectively).
Use this to create and show a third measure called Water-to-veg ratio, to get this pivot table:
Factory outlets have the smallest ratio (surely a fact worth shouting about).
Save your workbook as What about the desert, then close it down.
