Hello
I like to delete "k" from a string with the statement
update stamm set code = replace (code, 'k' , '');
But the only way to get the canditates I want to update is the following
statement. It seems that I can not update when I do a join.
Is there a way around it? With google I found a hint that a subselect
could help but there was no exsample ... And I did not found out how
to do this.
select a.code
from stamm a
where
a.skart in (
(select skart
from stamm
where code like '%k%')
)
and a.code not like '%V%';
I would be happy about a hint.
Thanks a lot
Michael
