Soweit mal die Lösung selber gefunden...

select e1.evname, e1.evdatvon, e1.evdatbis, mg1.status, group_concat(distinct mi1.vname separator ', '), mg2.status, group_concat(distinct mi2.vname separator ', '), mg3.status, group_concat(distinct mi3.vname separator ', ') from event as e1, mgevent as mg1, mgevent as mg2, mgevent as mg3, mitglied as mi1, mitglied as mi2, mitglied as mi3 where e1.evid = mg1.evid and mg1.status = 0 and mg2.status = 1 and mg3.status = 2 and mg2.evid = mg1.evid and mg3.evid = mg1.evid and mg1.mgnr = mi1.mgnr and mg2.mgnr = mi2.mgnr and mg3.mgnr = mi3.mgnr group by mg1.evid, mg1.status;


Wenn jetzt ein Event KEINE Teilnehmer mit einem Status "0" hat werden mir auch die anderen Stati nicht angezeigt....

Vielleicht hat jemand dafür noch ne Lösung
