mysqldump: Got error: 1168: Unable to open underlying table which is differently defined or of non-MyISAM type or doesn’t exist when using LOCK TABLES

用mysqldump命令备份数据库报如下错误

mysqldump: Got error: 1168: Unable to open underlying table which is differently defined or of non-MyISAM type or doesn't exist when using LOCK TABLES

解决办法：

备份添加–single-transaction参数

# mysqldump -uroot -p --single-transaction example  > example.sql

然后报错

mysqldump: Couldn't execute 'show create table `test`': Unable to open underlying table which is differently defined or of non-MyISAM type or doesn't exist (1168)

去数据库example查询表：test，果然没有这个表。

删除这个表

mysql> drop table test;
