PowerPivot | Date functions exercise | Compare this quarter's figures with last quarter's
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.
- 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.
Create a new workbook, and import into a PowerPivot data model the following two tables:
You'll also need to create the relationship shown above.
Use the PARALLELPERIOD function to show these figures:
|Measure||What it should show|
|This quarter||Total quantity sold for this quarter (add 0 quarters!)|
|Last quarter||Total quantity sold for the previous quarter|
|Quarterly ratio||The first divided by the second|
You should end up with something like this:
If you show figures by month, as here, the quarterly measures will repeat.
You'll need to use the IFERROR function to show blank values for the first quarters, to avoid divide-by-zero errors.
Save this workbook as Quarter master chores, and close it down.
