I have installed sqlyog and successfully created a database and restored database. Unfortunately, when I try to view column in sqlyog I get Error No. 1105. Also, I am unable to delete the database from sqlyog interface.
If you have access to the machine running MySql service, then you should check out MySql's data directory and see if the corresponding *.MYD file is there – or even the folder is there. I would remove the whole db manually, in case it's possible. Otherwise you should contact the operators of the server.
