修复mysql备份时提示损坏的表

在用mysqldump备份数据库时，遇到如下错误：

mysqldump: Got error: 144: Table ‘./DBNAME/TABLENAME’ is marked as crashed and last (automatic?) repair failed when using LOCK TABLES 

可采用如下方法解决：

mysql>check table TABLENAME;
 
+------------------------------+-------+----------+-------------------------------------------------------------------------------------------------+
| Table                        | Op    | Msg_type | Msg_text                                                                                        |
+------------------------------+-------+----------+-------------------------------------------------------------------------------------------------+
| DBNAME.TABLENAME             | check | error    | Table './DBNAME/TABLENAME' is marked as crashed and last (automatic?) repair failed |
+------------------------------+-------+----------+-------------------------------------------------------------------------------------------------+

mysql>repair table TABLENAME;

mysql>check table TABLENAME;

+------------------------------+-------+----------+----------+
| Table                        | Op    | Msg_type | Msg_text |
+------------------------------+-------+----------+----------+
| DBNAME.TABLENAME             | check | status   | OK       |
