In these cases, its certainly the best to rebuild your table
using a
CREATE TABLE new AS
SELECT col1,col1..
FROM old
GROUPY BY col1,col2...
If you have got many duplicates, recreating a new table
semms better to me than deleteing.
(Another advantage is that you still have the "bad" table as a record).
