accessing mysql/deleting tabels

Do you have phpmyadmin installed?

What OS are you using?

If you just need something occasionally, I'd suggest getting one of the GUI tools, install to your desktop, then connect remotely (via ssh tunnel).

From the SSH command line:

mysql -uUSERNAME -p DATABASE_NAME

Enter your MySQL password when prompted.

From the MySQL command line:

SHOW TABLES;
DROP TABLE TABLE_YOU_WANT_TO_DELETE;
