SSAS - tabular | Measures exercise | Using CALCULATE to split purchases into cheap and expensive
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 if you attend the course listed below!
- 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.
If you haven't already done so, create a new project called BaseModel, and import the following tables: tblCentre, tblCentreType, tblEnvironment, tblFamily, tblHabitat, tblProduct, tblPurchase, tblRegion and tblTown.
Delete any existing measures from your model, and create one to show the sum of the quantity of goods sold, to show in a pivot table:
Make sure you apply formatting to your measure too. Here we're showing the total quantity sold by family name.
Now use the CALCULATE function to create two measures as follows:
|Name||What it does|
|Cheap||Shows the sum of quantity sold where the price of the purchase is £10 or less.|
|Expensive||Shows the sum of the quantity sold where the purchase price is more than £10.|
Use these to show the following pivot table:
The figures shown here are by family, but they will remain correct whatever combination of slicers, row and column fields you choose to display.
Save your workbook as Pricey mammals then close it down.
