- 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.
Sadly, your company has appointed a new FD who insists that you should report in thirds, rather than quarters. The thirds should be named after his 3 pet cats:
| Third | Covers |
|---|---|
| Truffles | January, February, March and April |
| Sprout | May, June, July and August |
| Spot | September, October, November and December |
Start by importing all of the tables from the above database into a new model. You'll need to create a relationship between the tblCalendar table and the tblPurchase table via the PurchaseDate field:
Link these two tables as shown.
Create a new calculated column in the calendar table using this logic:
- If the MonthNumber column is less than or equal to 4, return Truffles;
- Otherwise if the MonthNumber column is less than or equal to 8, return Sprout;
- Otherwise, return Spot.
Use this to show a tree diagram proving that most sales are made in third 1:
