Which of the following is DML command?

Correct answer: INSERT INTO

Explanation: DML (Data Manipulation Language) commands operate on the data stored in tables — inserting, updating, deleting, or retrieving rows.

• Common DML commands: INSERT INTO (add rows), UPDATE (modify rows), DELETE (remove rows), SELECT (retrieve rows).

Why the other listed commands are not DML:

• DROP TABLE — This is a DDL command that deletes a table and its data; it changes the database schema.

• CREATE TABLE — This is a DDL command used to define a new table (schema definition), not to manipulate row data.

• ALTER TABLE — This is a DDL command used to modify the structure of an existing table (for example, add or drop columns).

Short summary: INSERT INTO manipulates table data (DML); DROP TABLE, CREATE TABLE, and ALTER TABLE manipulate the schema (DDL).
