Each of the following is a benefit provided by using views except for one. Which one? A) You can simplify data retrieval by hiding multiple join conditions. B) You can provide secure access to data by creating views that provide access only to certain columns or rows.

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; A) will fail because the GROUP BY clause isn't allowed in this view B) will fail because the column alias SumOfInvoices is invalid C) will fail because the ORDER BY clause isn't allowed in this view D) will succeed

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

The statement CREATE VIEW Example2 AS SELECT InvoiceNumber, DATEDIFF(day,InvoiceDate,InvoiceDueDate) FROM Invoices; A) will create an updatable view B) will create a read-only view because of a calculated value C) will fail because the second column isn't named D) will create a view through which you can delete rows, but not insert or update rows

The WITH SCHEMABINDING clause of the CREATE VIEW statement A) protects the view by binding it to the database schema B) prevents the tables that the view is based on from being deleted C) prevents the tables that the view is based on from being modified in a way that affects the view D) all of the above

D) all of the above

You can code views that A) join tables B) summarize data C) use subqueries and functions D) all of the above

D) all of the above

The WITH SCHEMABINDING clause A) prevents a row in a view form being updated if that would cause the row to be excluded from the view B) protects a view by binding it to the database structure C) prevents underlying base tables from being deleted or modified in any way that affects the view D) both b and c

D) both b and c

D) prevents other users from examining the SELECT statement on which the view is based

The statement CREATE VIEW Example4 AS SELECT * FROM Invoices JOIN Vendors ON Invoices.VendorID = Vendors.VendorID WHERE InvoiceTotal - PaymentTotal - CreditTotal > 0; A) will create an updatable view B) will create a read-only view C) will create a view through which you can update or insert rows, but not delete rows D) will fail because the SELECT statement returns two columns named VendorID
