Margaret [11]

d. SELECT

"SELECT" is a part of a DML statement.

What is DML?

DML, or Data Manipulation Language, is a subset of database operations used to insert, delete, and update data. A DML is frequently a sublanguage of a larger language, such as SQL; DML includes some of the language's operators. Because some users can perform both read and write selection, selecting read-only data is closely related to and sometimes considered a component of a DML.

Structured Query Language, or SQL, is a popular data manipulation language that is used to retrieve and manipulate data in a relational database. SQL allows you to perform database operations as well as create databases. SQL performs the required tasks by using specific commands such as Create, Drop, Insert, and so on.
