Which SQL command is required to remove a view from the database?

• A. DELETE VIEW ...
• B. DROP VIEW ...
• C. REMOVE VIEW ...
• D. UPDATE VIEW ...

Answer: (B)

The command required to remove a view from the database is "DROP VIEW ...". In SQL, the DROP statement is specifically designed to remove database objects such as tables, indexes, and views. When you execute the DROP VIEW command, you effectively delete the view definition from the database schema, which means that the view can no longer be used in queries.

Using the correct syntax, you would write DROP VIEW followed by the name of the view you want to remove. This operation is straightforward and serves to ensure that the database does not retain unnecessary or outdated views, helping maintain a clean and efficient database structure.

The other options do not accurately represent the SQL command used to accomplish this task. "DELETE VIEW ..." is incorrect because the DELETE statement is used for removing rows from a table rather than database schema objects. "REMOVE VIEW ..." is not a valid SQL command, and "UPDATE VIEW ..." does not apply since views cannot be updated directly; they are typically constructed from underlying tables. Therefore, the only valid and accurate command for dropping a view is DROP VIEW.
