MySQL seleziona dopo la riga su regole specifiche

Controlla questo:

WITH cte AS (
SELECT DATE(t1.`timestamp` - INTERVAL 5 HOUR) `date`,
       MAX(t1.`timestamp`) login, 
       MAX(t2.`timestamp`) online, 
       MAX(t3.`timestamp`) logout
FROM logging t1
JOIN logging t2 ON t1.`timestamp` < t2.`timestamp`
JOIN logging t3 ON t2.`timestamp` < t3.`timestamp`
WHERE t1.status = 'login'
  AND t2.status = 'online'
  AND t3.status = 'logout'
  AND NOT EXISTS ( SELECT NULL
                   FROM logging t4
                   WHERE t1.`timestamp` < t4.`timestamp`
