Hello all,
thanks for the answere to the prev. thread. With the help of them
I solved the problme I used "not like" instead of <> and this leads
to a problem. This works for me:
update stamm
set code = replace (code, 'k' , '')
where code like '%k%' and code <> '%V%';
I would still be interested to learn how to update a row when the result
set is only reachable via a join.
Thanks a gain
Michael
