SQL

SQL is a language used to interact with databases. It is used to create, read, update, and delete data in databases. SQL is a standard language for relational databases, but many databases use SQL with their own extensions. Learn SQL at Codecademy.

SQL example

CREATE TABLE users (
  id INT PRIMARY KEY,
  name VARCHAR(255),
  email VARCHAR(255)
);

INSERT INTO users (id, name, email)
  VALUES (1, 'Alice', 'alice@example.com')
  (2, 'Bob', 'bob@example.com')
  (3, 'Charlie', 'charlie@example.com');

SELECT * FROM users;

The result of the SELECT statement above would be:

id	name	email
1	Alice	alice@example.com
2	Bob	bob@example.com
3	Charlie	charlie@example.com
