Which SQL command is appropriate for a DBA to create a view displaying the top 10 products with the highest sales this year?

• A. CREATE VIEW TopProducts AS ...
• B. INSERT INTO TopProducts AS ...
• C. CREATE TABLE TopProducts AS ...
• D. ALTER VIEW TopProducts AS ...

Answer: (A)

The appropriate SQL command for creating a view that displays the top 10 products with the highest sales this year is the command that begins with "CREATE VIEW". This command is specifically designed for defining a view, which is a virtual table based on the result set of a SELECT query.

When using the "CREATE VIEW" statement, the DBA can encapsulate complex queries in a reusable format that simplifies access to the underlying data. The view can include the necessary logic to filter and sort the sales data, ensuring that only the top 10 products are displayed.

Other options, while related to database management, do not serve the purpose of creating a view. The "INSERT INTO" command is used to add new records to an existing table but does not create views. The "CREATE TABLE" command is for creating new tables in a database, which is not what is needed in this scenario. Finally, the "ALTER VIEW" command is designed for modifying an existing view rather than creating one from scratch. Hence, "CREATE VIEW" is the correct choice for this task.
