A Table which can be used for Partition Tests
The ID of the table can be used for Range Partitioning

create table bigtab (
    id      number(12,6),
    v1      varchar2(10),
    padding varchar2(50)
)
nologging   -- just to save a bit of time
/

insert /*+ append ordered full(s1) use_nl(s2) */
into bigtab
select
        3000 + trunc((rownum-1)/500,6),
        to_char(rownum),
        rpad('x',50,'x')
from
        all_objects s1,      -- you’ll need the privilege
        all_objects s2
where
