Casting and converting to show the correct average ticket price for each tour

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.

If you don't have a copy of the music database, first follow the instructions at the following link to create it: https://www.wiseowl.co.uk/oracle/exercises/oracle/using-oracle/5496/

Write a query to return the following columns from the Tour table, without any ordering:

List of tours

Your order may be different from this.

Add a calculated column called Avg_ticket_price which divides the tour gross by the attendance, and sort your query by this new column so the tours with the highest average price come first:

Average ticket prices

Use the CAST function to convert the average ticket price returned to an integer - NUMBER(5,0) for example.

As a reminder, the syntax of the CAST function is CAST ( value AS data_type),

Save the script as Tour prices.sql and then close it.

You can unzip this file to see the answers to this exercise, although please remember this is for your personal use only.
