dave, you leapfrogged right over what i was gonna teach him

betas, since you did not provide the agenda table, i removed it from the query

here's your query that i tried --
Code:
SELECT ticket.room, ticket.status, ticket.number
      , MAX(ticket.datum_status) 
  FROM ticket
 WHERE ticket.status IN(3,4) 
GROUP BY ticket.number
ORDER BY ticket.datum_status DESC LIMIT 6;
and here's the data it produced --
Code:
room status number   MAX(ticket.datum_status)

see? one row per ticket.number

notice, by the way, that the ORDER BY did not work correctly, i can explain this if you wish
