In SQL, create the query using the following entity-relationship model:
Retrieve a sales report for the years 2009 and 2010 summarizing PVFC sales by customer state. Only include customer states with multiple orders in a given year in the sales report. The query should output the year, customer state, number of orders in the year, the average order total, and total sales for the year. Sort the results first in ascending year, then ascending customer state. Hint: use the year function to return the year for a given date (year(date) returns year; e.g. year('9/1/2009') returns 2009).
