(Simple sorting) Based on the plumbing supply store database from Chapter 7, write SQL queries to perform the following tasks: A Show the name, unit price, units in stock, and units on order for each product, sorted alphabetically by product name. B Show the same information as in part (a), but sorted from the largest number of units in stock to the smallest. For products with the same number of units in stock, sort the rows of output from the largest number of units on order to the smallest. C Show the same information as in parts (a) and (b), and also the inventory position, which is the sum of the units in stock and the units on order. Sort the output from largest to smallest inventory position. D Show the same information as in part (c), and in the same order, but only for products with a unit price of at least $1,000.
