Correct option is B
The DROP SQL command is used to remove an entire table, including all of its data, from the database. Once a table is dropped, it cannot be recovered, and all its associated data and structure are permanently deleted.
Important Key Points:
1. DROP Command: The DROP command is used to delete a table or other database objects like views or indexes. It completely removes the table and all the data stored in it.
2. Irreversible Action: When you use the DROP command, all the data in the table is lost permanently, and the table structure is also removed from the database schema.
3. Removing Other Objects: The DROP command can be used for removing other objects such as databases, indexes, or views in addition to tables.
4. Database Integrity: Since DROP is an irreversible action, it should be used with caution. It's important to ensure that the table is no longer needed before dropping it.
Knowledge Booster:
· DELETE: The DELETE command is used to remove data from a table but does not remove the table itself. It allows for selective row deletion based on a condition.
· ERASE: The ERASE command is not a standard SQL command. It might be used in certain programming environments, but it is not a recognized command in SQL for removing tables or data.
