Please answer all three questions below using the Northwind and Hospital data models diagrams below.

1.) NORTHWIND: Write a query to list the customer company names and order dates for all orders placed in the first seven days of ANY AND ALL months during 1997. Have the results ordered by month and then by Day with each month.

2.) NORTHWIND: Write a user defined function that will accept as inputs a product ID and which will return the most recent date on which that product was ordered. Then write a query (not a stored procedure) that will list all product names, the value of inventory on hand (unit price x units in stock), and the last time the product was ordered by using the UDF you wrote.

3.) HOSPITAL: Write a query to list the name and assignment History for employee #12345. The assigmnet history is to include the department name and also the number of months the employee served in that assignment. (Do not worry about the fact that this cannot be calculated for the current assignment, at least with what we know now). For one bonus point describe what logic might allow you to calculate the length of the employee's current assignment, but don't worry to write the code.
