1.Create a stored procedure named spBalanceRange that accepts three optional parameters.
The procedure returns a result set consisting of VendorName, InvoiceNumber, and Balance for each invoice with
a balance due, sorted with largest balance due first. The parameter @VendorVar is a mask that’s used with
a LIKE operator to filter by vendor name, as shown in figure 14-5 of the text. @BalanceMin and @BalanceMax
are parameters used to specify the requested range of balances due. If called with no parameters,
the procedure should return all invoices with a balance due.

2.Code three calls to the procedure created in exercise 1 as follows:
(a) pass the parameters by position with @VendorVar='Z%' and no balance range
(b) pass the parameters by name with @VendorVar omitted and a balance range from $200 to $1000
(c) pass the parameters by position with a balance due that’s less than $200 filtering for vendors whose names begin with C or F

5.Create a scalar-valued function named fnUnpaidInvoiceID that returns the InvoiceID of the earliest invoice with an unpaid balance.
Test the function in the following SELECT statement:
SELECT VendorName, InvoiceNumber, InvoiceDueDate,
InvoiceTotal - CreditTotal - PaymentTotal AS Balance
FROM Vendors JOIN Invoices
ON Vendors.VendorID = Invoices.VendorID
WHERE InvoiceID = dbo.fnUnpaidInvoiceID()

8.Create a trigger for the Invoices table that automatically inserts the vendor name and address for a paid invoice into a table named ShippingLabels.
The trigger should fire for any time the PaymentTotal column of the Invoices table is updated.
The structure of the ShippingLabels table is as follows:
CREATE TABLE ShippingLabels
(VendorName varchar(50),
VendorAddress1 varchar(50),
VendorAddress2 varchar(50),
VendorCity varchar(50),
VendorState char(2),
VendorZipCode varchar(20))
Use this UPDATE statement to test the trigger:
UPDATE Invoices
SET PaymentTotal = 67.92, PaymentDate = '2008-08-23'
WHERE InvoiceID = 100

Here is the link to the DB files.
http://wikisend.com/download/150664/sql8_allfiles.zip
Also, The SQL statements should not include Cursor, fetch status, or Balance cursor.
It is for a beginners SQL class and these advanced statements should not be needed.
