will create an updatable view

The statement CREATE VIEW Example1 AS SELECT VendorName, SUM(InvoiceTotal) AS SumOfInvoices FROM Vendors JOIN Invoices ON Vendors.VendorID = Invoices.VendorID GROUP BY VendorName ORDER BY VendorName;

will fail because the ORDER BY clause isn't allowed in this view

will fail because the SELECT statement returns two columns named VendorID
