Which keyword is a DDL (data definition language) keyword in SQL?

The keyword "CREATE" is a DDL (Data Definition Language) keyword in SQL because it is used to define or create database objects such as tables, indexes, and views. DDL commands are primarily focused on the structure and schema of the database. For example, when you create a table using the CREATE command, you are defining its name, the columns it will have, and the data types of those columns.

In contrast, the other keywords listed—INSERT, UPDATE, and DELETE—are categorized under DML (Data Manipulation Language) since they are used to manage and manipulate the actual data within those structures. INSERT is employed to add new records to a table, UPDATE modifies existing records, and DELETE removes records from a table. Understanding the distinction between DDL and DML is fundamental in database management, as it helps in applying the right operations for specific tasks concerning a database.
