A collection of SQL commands known as the Data Manipulation Language (DML) are used to interact with and alter data kept in relational databases. Users can enter new data, update records that already exist, remove data that isn't needed, and retrieve data from the database with these instructions.
INSERT:
Adding additional data to a table is the goal.
Example: The INSERT command may be used to add a new employee's details, such as name, ID, and department, to a database that represents employees.
UPDATED:
To change the data that is currently in a table.
Example: You may use the UPDATE command to adjust the pertinent fields in the database if the job title or department of an employee changes.
To manage a database's content, DML commands are necessary. They enable users to add, edit, and remove data, maintaining the accuracy and timeliness of the database. Use of these commands should be done with caution because of the possible effects on consistency and integrity of the data. Furthermore, transactions may be used to group together different DML processes, guaranteeing that a sequence of changes either happens completely or not at all, preserving the data's integrity.
