SQL server

answer question 4 and 5

Exercises
1. Write a SELECT statement that returns two columns based on the Vendors
table. The first column, Contact, is the vendor contact name in this format:
first name followed by last initial (for example, "John S.") The second
column, Phone, is the VendorPhone column without the area code. Only
return rows for those vendors in the 559 area code. Sort the result set by first
name, then last name.
2. Write a SELECT statement that returns the InvoiceNumber and balance due
for every invoice with a non-zero balance and an InvoiceDueDate that's less
than 30 days from today.
3. Modify the search expression for InvoiceDueDate from the solution for
exercise 2. Rather than 30 days from today, return invoices due before the last
day of the current month.
4. Write a summary query that uses the CUBE operator to return LineItemSum
(which is the sum of InvoiceLineItemAmount) grouped by Account (an alias
for AccountDescription) and State (an alias for VendorState). Use the CASE
and GROUPING function to substitute the literal value **ALL*" for the
summary rows with null values.
5. Add a column to the query described in exercise 2 that uses the RANK()
function to return a column named BalanceRank that ranks the balance due in
descending order.
