Another variation to Mirjam's solution is to create the interim table and insert the rows that you want to keep as Mirjam said. Then run a
'delete all' on the production table which is very quick due to the fact that there is no journaling. After the delete is finished, do a straight
insert select back into the prod table from the interim table.
The rename option is probably the best but as Mirjam suggested, not everyone has the privileges to drop/rename tables.
