ALTER TABLE `xf_post`
ADD `type_data` MEDIUMBLOB NOT NULL AFTER `position`,
ADD `vote_score` INT NOT NULL,
ADD `vote_count` INT UNSIGNED NOT NULL DEFAULT '0',
ADD KEY `thread_id_score_date` (`thread_id`, `vote_score` DESC, `post_date`)

... so what did I end up doing since the 'DESC' piece kept effing up? (I failed in trying to switch from innodb to myisam engine)

I tried installing MariaDB alongside MySQL, that was a quick fiasco. I then blew away everything regarding mysql and mariadb (completely purged it all):

apt-get remove --purge mysql*
apt-get remove --purge mysql
apt-get remove --purge mariadb
apt-get remove --purge mariadb*
apt-get --purge remove mariadb-server
apt-get --purge remove python-software-properties

Keep in mind, I for sure kept a backup of my database for later access to import this all into MariaDB.

Anyway.. the solution was simply installing the MariaDB service, adding a user, importing the database in.

Yep.. that's all folks. No more silly database stuff, just running MariaDB from now on. Cool
