Write a query to return the following fields from the Tour table:
Who would pay to see a bad tour?
Add a calculated column using the DATEDIFF function to work out the length of each tour in days.
Add another column to calculate the daily revenue of a tour by dividing its gross by its length in days. Sort the results in descending order of this column.
Those are the sorts of numbers to get you out of bed in the morning!
Add a WHERE clause to show only the tours which lasted 1000 days or longer.
That's a long time to say goodbye.
Save the script as The Long and Winding Road.sql then close it.
