-rw-rw---- 1 mysql mysql 1024 1月 22 11:15 t_myisam.MYI
show fileds 开始执行时：
[root@10-19-187-240 tmp]# ll | grep sql
-rw-r--r-- 1 root root 531453 1月 10 19:55 a.sql
lrwxrwxrwx 1 root root 25 1月 9 18:14 mysql.sock -> /var/lib/mysql/mysql.sock

show filelds 执行完成 后：
[root@10-19-187-240 tmp]# ll | grep sql
-rw-r--r-- 1 root root 531453 1月 10 19:55 a.sql
lrwxrwxrwx 1 root root 25 1月 9 18:14 mysql.sock -> /var/lib/mysql/mysql.sock

-rw-rw---- 1 mysql mysql 1024 1月 22 11:15 t_myisam.MYI
[root@10-19-187-240 tmp]#
[root@10-19-187-240 tmp]#
把原来的文件 copy回来
[root@10-19-187-240 tmp]# cp ~/"#sql_5ec_0.MYD" ./
[root@10-19-187-240 tmp]# cp ~/"#sql_5ec_0.MYI" ./
[root@10-19-187-240 tmp]# ll

-rw-rw---- 1 mysql mysql 1024 1月 22 11:15 t_myisam.MYI再次执行show fields
就可以重现上面的错误
