PLEASE answer this question using the following table I have created. Thank you

Write a user-defined function named dbo.ProduceBill that accepts only the input parameter 'FolioID' to generate a printed bill (nothing fancy - using SELECT statements) displaying the guest's information (Name, address, etc) and Folio Details (Room # not id, Check-in Date) ONE TIME, followed all the folioBilling items for that folioid with a single Total Amount Due at end. Hint: Use a cursor. For each folioid, loop through (and sum) each billingitem (qty * amount) while FolioBillingID count > 0. Note: Functions do not allow print, so you need to be creative with SELECT.

Demonstrate this function TWICE with a query that contains folio ids (1 and 4).

I have already created these two functions that may or may not be used in this problem:

a user-defined function named dbo.GetRoomTaxRate which accepts a RoomID. The function will return a decimal value for the room's roomtaxrate.

a user-defined function named dbo.GetRackRate which accepts a RoomID and a date. The function will return a smallmoney value for the room's rackrate where the date provided falls between the start and end dates of the rackrate found
