1) An order history for customer 2118 has been requested. List the Order Number, Date, Manufacturer, Product, Description, and Order Amount for each order place by this customer. Use a WHERE clause to define the table join. Orders should be listed by OrderNum. 2) Change your solution from question 1 to use a NATURAL JOIN. 3) The inventory department has concerns on some high-priced product items kept in stock. These items were brought in specifically for individual customers. The concern is that the products dont seem to be selling as fast as they used to. The department is considering removing the products from inventory and ordering them in when ordered by a customer. List the Mfr, the Product, Custnum, Company and Price of all products brought by customers where CustNum is one of (2107, 2110, 2111, 2124) and where the price of the item is from $5.00 to $25.00. Order the results by ascending Company and then by Price. Use the JOIN keyword in your solution. 4) Normally, orders for a customer are placed by their salesrep. Sometimes a customer will place an order when their salesrep is away (sick, on vacation, etc). Write a query to list all orders where this has occurred. List the salesrep number and name (the salesrep to list is the one who was away when this order was placed) as well as the orderNumber and orderdate. 5) Management has noticed that the age of the managers seems to be less than the age of the salesreps that report to them. List all salesreps names and their managers names where the manager is younger than the salesrep. 6) Due to factory recalls, information is required on a series of products provided by our suppliers. List all orders (OrderNum) and the product that was ordered (manufacturer and product) that contain the following products: (41003 Manufactured by BIC, L12 Manufactured by FEA or XK48 Manufactured by QSA). Also show the customer number and company name placing the order, the name of the CustRep assigned to the company and the Office id where the CustRep works. Use the JOIN keyword in your solution.
