Delete based on rowid
Date: Mon, 5 Oct 2009 16:04:09 +0530
Have a simple question.
When we delete a row based on rowid from an indexed table, how the index entry gets deleted?
DELETE t WHERE rowid='<some rowid>';
Am asking this because in my case Oracle is doing a full index scan. Can we say deleting an indexed table based on rowid may not be the fastest way of deleting a row?
