Data Manipulation Language (SQL) (DML)

The SQL commands that add, change or remove rows: INSERT, UPDATE, DELETE and MERGE (and, in some classifications, SELECT).

Definition

DML changes data inside existing structures and runs within transactions that can be committed or rolled back. Some references put SELECT under DML, while others separate it as DQL.

Example

UPDATE Products SET Price = Price * 1.05 WHERE Category = 'Tools';

Exam tip

DP-900 groups SELECT under DML; CompTIA may list DQL separately. Read the answer choices carefully.
