LONG's maybe converted to LOB's via the TO_LOB SQL function.
There are strict limitations on this function: it can only be used in
the SELECT subquery of an INSERT statement.
e.g INSERT INTO lob_table
SELECT n, TO_LOB(long_col) FROM long_table;
As to which is better, LONG columns will convert to CLOB, and
LONG RAW to BLOB. There isn't any 'better', just 'different'.

Thanks all for the suggestions. I think I'll take a look at COPY and the
PL/SQL options since I've used them before, and C & Perl are not in my
repertoire, I'm ashamed to say ;) To shed a little more light on the
requirement, I'm researching the best (subjective) way to convert
dictionsry-managed TS's to locally-managed in an 8.1.7.3, Tru64 hosted DB
running SAP R/3. The convert-in-place procedure
[dbms_space_admin.tablespace_migrate_to_local] does not change extent
management for the segment.
Jared, I'd consider converting them, but SAP is a little posessive of
their
Clusters/Pools.

Mike,
Conner pointed out that you could use C.
You can also use Perl with DBI and DBD::Oracle if you like, and have
someone there that can use it.
Why not just convert them to CLOB and LOB?

OK, so you can't CTAS on tables with LONG or LONG RAW columns, and now I
find out that the same restriction exists on Alter Table ... Move. So,
is there any other option to move these tables from one tablespace to
another without exp/imp or converting them to LOB?
Thanks,
Mike
