EasyYatra is a travel booking company that has a web site available for customers to view and book their vacations online. You have been hired to look after the back-end SQL Server that is used to store customer and booking information. You are creating a table called Booking to keep track of vacations booked by customers. This table will contain a computed column called Total that is derived from other columns in the table.

To do this, you want to physically store the computed column in the table. How can this be done?

  1. Mark the computed column as PERSISTED.

  2. Define the computed column as NULL.

  3. Specify the collation for the column using COLLATE Physical.
