Yes, but direct SQL with CTAS is faster. Of course, could put nologging on table after creation but then need separate ddl script. Still like CTAS.

You can do it in pl/sql.
In our table SUB, the field user_area is not just a long, but a long raw.
Do something like this:
pre_create sub_temp
declare
cursor c_1 is select * from SUB;
begin
for r1 in c_1 loop
insert into DISCUS.SUB_temp (
RRN ,
LOG_DATE_TIME ,
TRANS_AREA ,
USER_AREA )
Values(
r1.RRN,
r1.LOG_DATE_TIME,
r1.TRANS_AREA,
r1.USER_AREA
);
end loop;
commit;
exception
when others then
rollback;
raise;
end;
