今早想对我的mysql测试库做个备份的时候出现错误如下：
[root@meizi ~]# mysqldump -uroot -p goolen > goolen.sql        
Enter password: 
mysqldump: Got error: 1146: Table 'goolen.ggschkpt' doesn't exist when using LOCK TABLES

[root@meizi ~]# mysql -uroot -p
Enter password:

60 rows in set (0.00 sec)

这个库已经设置了不区分表名大小写，所以应该不是大小写的问题
[root@meizi goolen]# cat /etc/my.cnf | grep lower_case
lower_case_table_names=1

这个表是在测试ogg的时候创建的表，一直没有动过，不是重要的表
去文件系统上查了一下，发现只有.frm的文件，直接删掉这2个文件
[root@meizi goolen]# rm -rf GGSCHKPT.frm 
[root@meizi goolen]# rm -rf GGSCHKPT_lox.frm

再次导出数据已经正常
[root@meizi goolen]# mysqldump -uroot -p goolen > goolen.sql
Enter password: 
[root@meizi goolen]# ls goolen.sql 
goolen.sql
