Data Manipulation Language (DML) is a subset of SQL (Structured Query Language) that is used to manipulate data in a relational database. DML includes a set of commands for performing operations such as inserting, updating, and deleting data in database tables.
Some common DML commands include:
SELECT: used to retrieve data from one or more tables in a database.
INSERT: used to insert new data into a table.
UPDATE: used to modify existing data in a table.
DELETE: used to delete data from a table.
MERGE: used to merge data from multiple tables into a single table.
REPLACE: used to insert new data into a table or update existing data.
Data Manipulation Language (DML) is a subset of SQL used to interact with data stored in a database. It allows users to perform operations like inserting, updating, deleting, and retrieving data. Common DML commands include INSERT, UPDATE, DELETE, and SELECT. These commands enable efficient data handling while ensuring consistency and integrity within the database.
Data Manipulation Language (DML) operations directly interact with the data, making it a core part of database management. Unlike Data Definition Language (DDL), which deals with schema and structure, DML focuses on modifying the actual data while adhering to database constraints and ensuring transactional integrity.
