You should run into out of memory scenaria. OS is keeping to free some
memory that delay mysql connection.

I try to generate a unique id for each row in a Mysql-InnoDB Table.
Because of many deletes I can't use an auto_increment column.
After a Mysql restart, the next value for an auto_increment-column is
max(auto_increment-column)+1, and I need a really unique id.
[JS] See if the UUID()
Why would the auto_increment not work for you? The only case where you
would have a problem is if the last record was deleted before mysql
shutdown. If you are really concerned about this unique scenario,
insert a dummy record before shutdown to guard against it and delete
the dummy record

Hello and Greetings mysql,
I have been running a WAMP server for some time on my Windows XP Pro
box. Over time I have gone through some issues about which WAMP to use
and last Year converted my Apache2Triad installation to WAMP5. All of
my database installations, out of preference, have been
If you have both myisam and innodb.
You need to ensure sql's from myisam and sql's from innodb have sufficient
memory to run.
you can allocate 25% of you RAM to key_buffer used exclusively for myisam
and around 60% of your RAM to innodb_buffer_pool for supporting innodb .

Hi Anada,
I recommend MySQL Database Design and Tuning by Robert Schineider. It
covers everything from benchmark testing to Innodb Performance
Enhancements. I'm 85% done with the book myself. It shows and explains
good command-line and MySql Admin tool examples. The techniques

Absolutely... replication is designed to work across heterogenous
systems: I used to work at a place that ran replication from Mac OS/X

There were no extra magic steps.
Having said that, debian and fedora are flavours of the same

I want to remove all records from 'feed_tag' where the feed_id foreign key
doesn't have any corresponding records in feed.
For instance I may have a record in feed_tag that is like (23, 10, 4543,
'... (some date)').
Then lets say there is no record in feed that has a primary id key of 10.

Hi Daevid
If you are using a foreign key you can set the reference as cascade
and when a row is deleted from feed it will be deleted from feed_tag.
http://dev.mysql.com/doc/refman/5.0/en/innodb-foreign-key-constraints.html
If you don't like it you can delete it easy with a query like this
Just do a left join with the delete query.
DELETE feed_tag FROM feed_tag LEFT JOIN feed ON
feed_tag.feed_id=feed.id WHERE feed.id IS NULL
That should do it. You can change DELETE feed_tag to SELECT and
test it first.
