Which command would be used to add a record under specific criteria?

The command used to add a record under specific criteria in a database is the "INSERT INTO" command. This SQL command is specifically designed to insert new records into a database table. When using "INSERT INTO," you specify the target table and the values for the fields you want to populate, effectively creating a new entry based on the specified criteria.

For example, if you have a table for storing user information, using the "INSERT INTO" command allows you to add a new user with defined attributes, such as name, email, and age. This operation is fundamental in creating and managing data within relational databases, providing a way to expand data sets according to the requirements of the application.

The other commands serve different purposes: "UPDATE" modifies existing records, "SELECT" retrieves data from a database without altering the data, and "DELETE" removes records from a table. Each of these commands plays a crucial role in database management but does not pertain to the action of adding new records.
