Before you can do this exercise, you'll need to download and unzip this file (if you have any problems doing this, click here for help).

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 contains a table of course products called tblCourse:

SQL exercise - Variables (image 1)

These are courses which COULD run

The database also contains a table called tblSchedule, containing courses actually running:

SQL exercise - Variables (image 2)

Ignore the TrainerIds and ResourceIds columns for now

Create a query using an inner join between these two tables.  Your query should read the following columns for schedule number 17 (not shown above) into 3 variables:

  • The course name
  • The start date
  • The number of days the course lasts

Extend this query so that it prints out this information, using the 3 variables that you have created and assigned values to:

SQL exercise - Variables (image 3)

Sample output from your query

Optionally, save this query as Assign course columns to variables.sql, then close it down.
