DML Data Manipulation Language

DML statements affect records in a table. These are basic operations we perform on data such as selecting a few records from a table, inserting new records, deleting unnecessary records, and updating/modifying existing records.
DML statements include the following:

INSERT – insert new records
UPDATE – update/Modify existing records
DELETE – delete existing records
