Database Errors

My Database guru is away at the moment and im getting bombarded with errors since applying the expand/collapse hack. T

The hack works fine and the forum is working fine but im getting errors through like anything.

Invalid SQL: UPDATE user SET forumviewset='' WHERE userid='13'
mysql error: Unknown column 'forumviewset' in 'field list'

mysql error number: 1054

and

Database error in vBulletin :

cannot use database meetingbar
mysql error: Unknown database 'meetingbar'

mysql error number: 1049
