Write a query to select rows from the Tour table where the Attendance is greater than average. Sort the results in ascending order of Attendance.
The first few results you should see.
Add a column which calculates the difference between each tour's attendance and the average of tour attendance.
You'll need to include a subquery in the SELECT list to get these results.
Write a query to calculate the total length in seconds of albums in the Album table.
Use a subquery to return the albums which are longer than average, but by no more than 60 seconds. Include a column which shows how much longer than the average each album is and sort the results in descending order of length.
The first few results you should see.
Save the script as Give Me a Minute.sql and then close it.
