SQL | Archived exercise | Show end date for given course
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.
The answer to the exercise will be included and explained if you attend the relevant Wise Owl course (sadly, only in the UK for now).
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 stored procedure in the above folder to generate a database of training courses and delegates. This exercise refers to columns from the following two tables:
Each course product can have lots of instances of the course scheduled
Create a function called fnEndDate which takes in:
- The start date of a course; and
- The number of days it lasts
Your function should then return the end date of the course.
Use the DateAdd function to work out the end date: the syntax is DateAdd ( day, Number of days to add, Start date) .
Incorporate your function within a query to show the start and end dates of all courses which start and end within January 2010:
You should see six courses
Optionally, save this query as Course end date function.sql, then close it down.
