SELECT department, COUNT(*) FROM employees
GROUP BY department;
-> Count employees per department
SELECT department, AVG(salary) FROM employees
GROUP BY department
HAVING AVG(salary) > 60000;
-> Departments with avg salary > 60k
====================================
JOINS โ Most Asked in Interviews!
INNER JOIN -> Only matching rows in both tables
SELECT e.name, d.dept_name
FROM employees e
INNER JOIN departments d
ON e.dept_id = d.id;
LEFT JOIN -> All rows from left + matching right
