WITH WHO_IS_TOP_DOG (EMPLOYEEID, LASTNAME, FIRSTNAME, REPORTSTO, LEVEL) AS
(
	--ANCHOR
	SELECT EMPLOYEEID, LASTNAME, FIRSTNAME, REPORTSTO,  0 AS LEVEL
	FROM EMPLOYEES 
	WHERE REPORTSTO IS NULL
	
	UNION ALL
		
	--RECURSIVE
	SELECT E.EMPLOYEEID, E.LASTNAME, E.FIRSTNAME, E.REPORTSTO, LEVEL + 1
	FROM EMPLOYEES AS E
	INNER JOIN WHO_IS_TOP_DOG AS W
	ON E.REPORTSTO = W.EMPLOYEEID
)
SELECT * FROM WHO_IS_TOP_DOG
