I don't have the update for the questlog table, but here is the table structure.
Code:
CREATE TABLE `questlog` (
`player_guid` bigint(20) unsigned NOT NULL default '0',
`quest_id` bigint(20) unsigned NOT NULL default '0',
`slot` int(20) unsigned NOT NULL default '0',
`time_left` bigint(20) NOT NULL default '0',
`explored_area1` bigint(20) unsigned NOT NULL default '0',
`explored_area2` bigint(20) unsigned NOT NULL default '0',
`explored_area3` bigint(20) unsigned NOT NULL default '0',
`explored_area4` bigint(20) unsigned NOT NULL default '0',
`mob_kill1` bigint(20) NOT NULL default '0',
`mob_kill2` bigint(20) NOT NULL default '0',
`mob_kill3` bigint(20) NOT NULL default '0',
`mob_kill4` bigint(20) NOT NULL default '0',
PRIMARY KEY (`player_guid`,`quest_id`)
) ENGINE=MyISAM AUTO_INCREMENT=33067588 DEFAULT CHARSET=latin1;
