Create a store procedure named spBalanceRange that accepts 3 optional parameters. The procedure returns a result set consisting of VendorName, InvoiceNumber and Balance for each invoice with a balance due, sorted by largest balance due first. The parameter @VendorVar is a mask thats used with a LIKE operator to filter by vendor name. @MinBalance and @MaxBalance 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.
