Delete/truncate

Question

Hi,
I'm looking for a way of deleting rows quicker than the delete dml sentence.
I know truncate sentences, but i don't want to truncate a table or a partition, I want to delete a great number of rows (identified by a where clause), but not a whole partition or table.
For example, inserting rows i can use insert sentences or i can use sql-loader, ¿is there something similar deleting rows??
My problem is deleting time.
Any advice will be greatly apreciatted. Thanks in advance
Juan

You could also try (what Tom Kite calls) DIY Parallelism.
That's where you do DML against ranges in your table at the same time using separate sessions:
delete your_table
where some_column between 1001 and 2000;
commit;
in a separate session:
delete your_table
where some_column between 2001 and 3000;
commit;
Do this for as many sessions as necessary. I've used 8 with good results.
The ranges must be mutually exclusive and roughly the same number of rows.
