Which SQL command permanently removes an entire table along with all of its data, structure, and associated constraints from a database?
DROP TABLE
TRUNCATE TABLE
ALTER TABLE
DELETE FROM
The DROP TABLE command is a Data Definition Language (DDL) statement that deletes the table's structure and all data it contains. After execution, neither the rows nor the table definition remain unless a backup is restored. DELETE FROM only removes selected rows while preserving the table structure, TRUNCATE TABLE removes all rows but keeps the structure intact, and ALTER TABLE modifies an existing table's definition without deleting it.
