: Problem with CREATE TABLE/DROP TABLE
I'm having the issue with CREATE TABLE described by Bug #30513
(http://bugs.mysql.com/bug.php?id=30513
). To summarize, a table which previously existed, and then is dropped
by DROP TABLE IF EXISTS, becomes randomly unable to be recreated. Here
is my comment

I tried with mysqldump and SELECT INTO but when import the data on the destination server, the
BLOB data

In either case the speed to get a COUNT() is largely down to the speed

read every row in order to count them, and any large table is probably
larger than your caches.

I get incorrect result when searching for the norwegian character 'å'

Make sure that your table has:

Mark, is the 'secs' column the offset from the minimum value of the
timestamp column?
If so, you might try something like this:
SELECT UNIX_TIMESTAMP(MIN(timestamp)) INTO @min_timestamp FROM my_table;
SELECT uid, timestamp,
UNIX_TIMESTAMP(timestamp) - @min_timestamp AS secs
FROM my_table
ORDER

That tool tells me 100% of the data is read from memory, not a byte from

Any suggestions to where to go from here?
I dunno. My hunch is that could do some query
I have the following 2 tables:
CREATE TABLE media (
id int(10) unsigned NOT NULL auto_increment,
user_id int(10) unsigned default NULL,
title varchar(255) NOT NULL,
description text NOT NULL,
`hash` varchar(255) NOT NULL,
length float(9,2) NOT NULL,
created timestamp NOT NULL

MySQL (5.0.45) seems to be the problem. It's almost constantly running

It usually knows better than you do about indexes.

You may be encountering a thrashing problem with the amount of memory
left or any number of things, but I would look at memory use on this
box, because your load is pretty high and your performance is
suffering

I think you've got an application problem somewhere which you should
