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 on the relevant Wise Owl classroom training course (sadly for the moment only in the UK).
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.
In the above folder are 3 Excel files containing information about the tallest buildings in various countries. The aim is to be able to switch between viewing the top 10 from each file by changing to which file we are connecting:

The & is used to concatenate the string connection with the value inside the parameter.
Exit Query Editor and then use Edit Parameters under Edit Queries to switch to a different file:
You may need to click Apply changes to finish loading the data.
Optionally save this as Tall, Taller, Tallest and then close it down.
