Hallo, durch den Geburtstag gibt es ja noch keine ganz sichere Eindeutigkeit. Jetzt habe ich beim WinSV-Programm in den Rohdaten einen eintrag entdeckt (1707) fast am Ende der Zeile, der anscheinend eine Nummerierung der Schüler ist. "BE***","RS 5 A M BE****",1949,"Be***","","","****","****","**","","03.05.1991","1991","Lichtenfels","D","RK","Be****","Georg und Angelika","U","EL","","","","","","","96**","Z*****","A****","095*****","EL","S","","","","","","","N","471214","","","","","","","","","","ZA","","","","5 A",5,"","","RS VS","","RS","","","","","KR","","","","","","","","","","","","","","","","","","","","","",0,5,0,0,0,"5 &","S","","","","","","","","","","",0,0,"","","","","","","","","","","","17****","",5,"","P","","","","","","5636","VS",5,"","","","","","","","","","","","","","","",0,"","","","","","","","","","","2","1","1","","","","","0*****","0","","","","","","","","","","","","",0,"","","","","","","","","","","","","","","","","","","","","","","",1707,"","","","","","","",5,"","-","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",0,"","" Eine Frage an die WinSV-Exerten. Ist diese Nummer eindeutig an einen Schüler gebunden, was passiert, wenn der Schüler die Schule verlässt, wird dann diese Nummer neu vergeben, oder wird einfach immer weiter gezählt. Wäre diese Nummer nämlich zumindest ein Schulleben an einen Schüler gebunden, könnte man diese ja zum Namen hinzufügen und schon wäre eine absolute Eindeutigkeit gegeben. Viele Grüße Dieter
