Violation of PRIMARY KEY constraint 'Table1$PK_KndNr'. Cannot insert duplicate key in object 'dbo.Table1'.

Fax, Natel, Email, Geburtsdatum,ZahlungsKondition)

select distinct Kundennummer,Anrede,Name,Vorname,Zusatz,Strasse,Ort,[Telefon 1],[Telefon 2],
Fax,Natel,[E-Mail],Geburtstag,1

from table2
WHERE not exists (select * from Table1
                  where Table1.KndNr = table2.Kundennummer);
