SELECT name, salary
FROM employee, info
WHERE employee.id = info.id;

SELECT e.name AS name, i.salary AS salary
FROM employee AS e
INNER JOIN info AS i
ON e.id = i.id;

SELECT e.name AS name, i.salary AS salary
FROM employee AS e
INNER JOIN info AS i
ON e.id = i.id;

SELECT name, salary
FROM employee, info
WHERE employee.id = info.id;
