Create a query to return the following columns from the Artist, Tour and Show tables:

A list of music shows produced by a SQL Server query

The first few rows you should see.

Feel free to use the Query Designer to help with the joins you'll need.

Modify the query to GROUP BY the Artist and Tour_name columns, summing the TIckets_sold and Revenue_$ fields and sorting the results in descending order of total revenue.

A list of concert tours, tickets sold and revenue generated produced by a SQL Server query using a group by clause.

The results of the grouped query.

Use the query to create a stored procedure called usp_Tour_Totals.

Execute the script to create the procedure and then test that the procedure works.

Alter the procedure so that it also returns the average of TIckets_sold and Revenue_$ and sort the results in descending order of the average revenue. Test that the procedure returns the extra columns when you execute it.
