identity/automatic increment with DDS

Hello everyone. Hoping this is the right list for this question...

Is it possible to create a table with an automatically generated column (an
'identity' in DB2, autonum or auto_increment in different DBs) using DDS, or
I can only create it using SQL?

E.g, having this SQL query, would it exist an DDS equivalent?
CREATE TABLE ivan/ALFVISCL7
(
id BIGINT GENERATED ALWAYS AS IDENTITY
     (START WITH 1, INCREMENT BY 1 MINVALUE 1 NO MAXVALUE NO CYCLE NO ORDER
CACHE 20)
     not null,
textito VARCHAR(30)
);

Thanks for any info, and regards.

I.-
