THIS IS AN SQL PROBLEM PLEASE SHARE CODE AND RESULT FROM QUERY
6. Write a SELECT statement that returns a single value that represents the sum of the largest unpaid invoices submitted by each vendor. Use a derived table that returns MAX(InvoiceTotal) grouped by VendoriD, filtering for invoices with a balance due.
7. Write a SELECT statement that returns the name, city, and state of each vendor that's located in a unique city and state. In other words, don't include vendors that have a city and state in common with another vendor.
8. Write a SELECT statement that returns four columns: VendorName, InvoiceNumber, InvoiceDate, and InvoiceTotal. Return one row per vendor, representing the vendor's invoice with the earliest date.
9. Rewrite exercise 6 so it uses a common table expression (CTE) instead of a derived table.
