我有一个无法删除的空数据库。最初，它包含一个我无法从中选择的表。因此，我删除了该数据库中的所有表，并试图删除该数据库，但没有成功：
mysql> drop database my_database;
ERROR 2013 (HY000): Lost connection to MySQL server during query
现在我有一个空数据库，无法在服务器中删除。
我检查了mysqlerror.log，这里是输出：
130812 10:02:45 InnoDB: Assertion failure in thread 140409656780544 in file row0mysql.c line 3682

This could be because you hit a bug. It is also possible that this binary
or one of the libraries it was linked against is corrupt, improperly built,
or misconfigured. This error can also be caused by malfunctioning hardware.
We will try our best to scrape up some info that will hopefully help
diagnose the problem, but since we have already crashed,
something is definitely wrong and this may fail.
key_buffer_size=16777216
read_buffer_size=131072
max_used_connections=3
max_threads=151
thread_count=3
connection_count=3
It is possible that mysqld could use up to
key_buffer_size + (read_buffer_size + sort_buffer_size)*max_threads = 346685 K bytes of memory
Hope that's ok; if not, decrease some variables in the equation.

where mysqld died. If you see no messages after this, something went
terribly wrong...

我试着设置配置innodb_force_recovery = 4并重新启动MySQL，但根本没有效果。
此处不允许重新安装服务器。它发生在许多机器上（2个Ubuntu和2个CentOS），但我现在无法重现这个问题。
我认为这与InnoDB表损坏有关。我也有类似的问题，能够把它精确到一张桌子上。我仍在通过复制表和删除对我来说不好的单个记录来纠正这个问题。
这个链接对我有很大帮助：
恢复InnoDB表损坏
很抱歉答案不完整，但一旦我找到它，这对我帮助很大。
