Sql Query:
 
SELECT ticket.tn, ticket.id,ticket_history.state_id,ticket_state.name, max(ticket_history.change_time) AS change_time 
FROM ticket_history 
LEFT JOIN ticket ON (ticket.id = ticket_history.ticket_id) 
LEFT JOIN ticket_state ON (ticket_state.id = ticket_history.state_id)
 LEFT JOIN ticket_state_type ON (ticket_state_type.id = ticket_state.type_id)
 WHERE ticket_history.history_type_id = 27 AND 
ticket_state_type.name !="closed" 
GROUP BY ticket.tn;


At the moment it just groups the records and only gets the max date and not the row associated with the max date
