Hi Wenjun,
thanks very very much for your help, but unfortunately it's not that what I am looking for.
I would like to create a sequence and use this sequence in the CREATE TABLE command of different tables.
I managed to create a table to use the sequence in the insert command, this works, but I don't get in run with the create table statement, although it's described.
this works here:
create column table "bla1" (no1 integer, text1 varchar(10));
insert into "bla1" values (ww_seq.nextval, 'hugo');
best regards
Wolfgang
