Subj:   Re: Delete Query on a huge table taking too much time
 
From:   Mark Ferguson

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.
