Corrupted mysql cache_rules table - dropped the table and now I cannot create it anymore!? Stuck
I tried dropping the database multiple ways. via command line and phpmyadmin. none of that worked.

What did work was going into the database files directory and deleting it manually. These mysql database tables are just regular files you can delete. Mine were located here: /var/lib/mysql/ 

here's what i did: 



After that I was able to recreate the table via mysql command line. just copy and paste this to recreate the table with the schema:

CREATE TABLE `cache_rules` (`cid` varchar(255) NOT NULL DEFAULT '' COMMENT 'Primary Key: Unique cache ID.', `data` longblob COMMENT 'A collection of data to cache.', `expire` int(11) NOT NULL DEFAULT '0' COMMENT 'A Unix timestamp indicating when the cache entry should expire, or 0 for never.', `created` int(11) NOT NULL DEFAULT '0' COMMENT 'A Unix timestamp indicating when the cache entry was created.', `serialized` smallint(6) NOT NULL DEFAULT '0' COMMENT 'A flag to indicate whether content is serialized (1) or not (0).', PRIMARY KEY (`cid`), KEY `expire` (`expire`)) ENGINE=InnoDB DEFAULT CHARSET=utf8 COMMENT='Cache table for the rules engine to store configured items.';
