Normally when you delete an entry from an index, if the deletion causes an index block to become half-empty (or 25%, or whatever; depends on the algorithm), mysql will start coalescing index blocks. This results in a smaller, more efficient index. If you are simply deleting a bunch of records only to re-insert new ones, there's not much use in trying to optimize the index halfway through the operation. -- Dan Nelson [EMAIL PROTECTED] --------------------------------------------------------------------- Before posting, please check: http://www.mysql.com/manual.php (the manual) http://lists.mysql.com/ (the list archive) To request this thread, e-mail <[EMAIL PROTECTED]> To unsubscribe, e-mail <[EMAIL PROTECTED]> Trouble unsubscribing?
