Open the Venue Sizes.sql file from the folder shown above. You'll find a query which calculates some values for a list of venues.
Some of the values may be different when you run the query.
Your job is to use the existing query as a derived table subquery in the FROM clause of another SELECT statement. Begin by adding a new SELECT FROM statement above the existing query.
Don't worry about the syntax errors for now.
Now wrap the subquery in a set of round brackets and assign an alias to it.
This will help with some of the syntax errors.
Modify the outer query to group the results by the Venue_size column and show the following statistics:
These results have been sorted in descending order of the Avg_Cost_$m column.
Save and close the file.
