I am trying to extract name of employee who is reported by 5 or more employees on leetcode:
Accepted code:

FROM Employee AS EMP1
JOIN(
SELECT managerId
FROM Employee
GROUP BY managerId
HAVING COUNT(managerId) >= 5
) AS EMP2
ON EMP1.id = EMP2.managerId
Rejected code:
SELECT name
FROM Employee
HAVING COUNT(managerId) >= 5
