SQL | Variables exercise | STORED PROCEDURE with single vbl to calc age
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 one of more of the courses listed below!
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.
Make sure that you're using a sensible database (it doesn't really matter which for this example).
Create a stored procedure called spCalculateAge which:
- Declares an integer variable called @Age
- Sets the value of this variable to be the difference in years between your date of birth and today's date (see hint below)
- Prints out your age
The final result of running the stored procedure should look like this:
You will be younger, of course ...
You can use the DateDiff function to calculate your age in SQL - eg DateDiff(year,'03/04/1964',GetDate()) would give the age of a hypothetical trainer born on 4th March 1964.
Optionally, save the query to generate this stored procedure as Calculate your age.sql, then close it down.
