The DESTROY option on an import indicates whether the CREATE TABLESPACE commands only
found in a full export should be executed. Setting DESTROY=Y destroys the data files
of the database being imported into. This is only used when you want to rebuild an
entire database, not to overwrite data in tables. If you really need the empty all the
tables in a schema, disable the constraints on the tables, truncate them, and reenable
the constraints. This will only work if the schema is self contained, and it's tables
are not used as a foreign key for a table in a different schema.

IIRC, there is a flag for import "destroy=y" to do what you want. This is
very dangerous and you should research all the implications before trying
it. If you don't have the docs, try http://technet.oracle.com and read up
on the import options.
