Solution
DML stands for Data Manipulation Language. It is a type of language used to manage data in a database. The main operations that can be performed using DML are SELECT, INSERT, UPDATE, and DELETE.
- SELECT: This command is used to select data from a database. The data returned is stored in a result table, called the result-set.
Example:
SELECT * FROM Students;
This command will select all data from the "Students" table.
- INSERT: This command is used to insert new data into a database.
Example:
INSERT INTO Students (StudentID, LastName, FirstName, Age) VALUES (1, 'Smith', 'John', 18);
This command will insert a new row into the "Students" table.
- UPDATE: This command is used to modify the existing records in a database.
Example:
UPDATE Students SET Age = 20 WHERE StudentID = 1;
This command will update the age of the student with the ID of 1 to 20.
- DELETE: This command is used to delete existing records from a database.
Example:
DELETE FROM Students WHERE StudentID = 1;
This command will delete the student with the ID of 1 from the "Students" table.
