SQL Query:-
"
CREATE OR REPLACE TABLE employees (
employee_id INT,
employee_name VARCHAR(50),
department_id INT
);

-- Populate employees table
INSERT INTO employees (employee_id, employee_name, department_id)
VALUES
(1, 'John', 101),
(2, 'Alice', 102),
(3, 'Bob', 101),
(4, 'Jane', 103),
(5, 'Tom', 102);

-- Create departments table
CREATE OR REPLACE TABLE departments (
department_id INT,
department_name VARCHAR(50)
);

-- Populate departments table
INSERT INTO departments (department_id, department_name)
VALUES
(101, 'HR'),
(102, 'Engineering'),
(103, 'Marketing');




-- Perform a natural join between employees and departments tables

SELECT *
FROM employees
NATURAL JOIN departments;
