mySQL错误:引擎中不存在表'表'

突然之间,我的mysql数据库表出现了一个奇怪的错误。

SELECT * FROM mytable

返回:

ERROR 1932 (42S02): Table 'mydb.mytable' doesn't exist in engine

我可以确认这些表确实存在于本地文件系统中,show tables;确实返回了我感兴趣的表。

show tables;

+-----------------+
| Tables_in_mydb  |
+-----------------+
| presets         |
| mytable           |
+-----------------+

选择:

select * from mytable;

Table 'mydb.mytable' doesn't exist in engine. 

错误绝对没有意义,我几天前一直在使用这些表而没有任何问题。我没有动过桌子。我该怎么办?

在上述错误出现之前我遇到了错误:

Access denied for user 'root'@'localhost' (using password: YES),

但我成功更新了密码。我不知道是什么触发了这个错误,因为我没有玩过密码。但是,当我尝试修复此错误时,我已将/Applications/XAMPP/xamppfiles/var/mysql的权限设置为read/write给所有人。

UPDATE:

show table status gives back a really weird outout:

SHOW TABLES结果看起来有些偏差。该框在mytable行上有更多空间。某种程度上,你的表名中是否有可能存在隐形字符?也许你创造错了?
