hai Anke,
c if u wanna compare the atest value with the btest value here is the query

select * from (select GEMARKUNG from atest
minus
select GEMARKUNG from btest) b,atest a where
a.GEMARKUNG =b.GEMARKUNG

for comparing btest with atest value then query is

select * from (select GEMARKUNG from btest
minus
select GEMARKUNG from atest) b,btest a where
a.GEMARKUNG =b.GEMARKUNG

with regards
Shyam

Thanks, bu I have my problem not right said. In the end of my task,
I have to update the column rechtswert,hochwert from btest with the column rechtswert,hochwert from atest with the difficult identify.
In my excample is that atest.gemarkung,atest.flur,atest.flst_nr 2222,1,123/100 = btest.gemarkung 2222/001/12345/0010.
I hope you understand me.
Thanks for the help
Anke
