Re: Restoring a table with a different name

You may be better off with renaming the existing table, importing, then
doing more renaming to get everything in the right place:

alter table memmast rename to memmast_temp;

<import table>

alter table memmast rename to wk_memmast;

alter table memmast_temp rename to memmast;

That way you don't need to muck with the dump file.
