In SQL, write the query using the instructions and the model below:

Retrieve a list of salespersons and the orders they have each facilitated, including order ID,

order date, and order total. Each order facilitated by a salesperson contributes to their

total sales. Also provide the contribution of each order to the salesperson's total sales, as a

percentage of total sales. Round the percentage of total sales to two digits beyond the

decimal point using the 'round' function - round(#,2) where # is the number to round. The

query should output the salesperson name, order ID, order date, order total, and

percentage of salesperson total sales. Sort the list first in alphabetical order of salesperson

name, then by ascending order date, and then with larger order totals listed first.
