And then by doing CTASD you will loose all grants,synonyms etc ... I wonder how long it would take to delete 5000 rows. Create unique constraint and catch exceptions into an exceptions table (created with $OH/rdbms/admin/utlexcpt.sql) ... From there on it should be easy ...

CTASD (create table as select distinct) followed by a DROP and a RENAME?
