**1，Mysqldump的时候报错如下：**

2014-05-05 14:12:37 7f004a9a2700 InnoDB: Error: Table "mysql"."innodb\_table\_stats" not found.

但是show tables我看这个表示存在的：

![SouthEast][]

但是show create table innodb\_index\_stats;报错如下：

mysql> show create table innodb_index_stats;
    
    ERROR 1146 (42S02): Table'mysql.innodb_index_stats' doesn't exist
    
    mysql>

**2，估计是表坏了，去数据库服务器上面的mysql库的目录看下这些表的数据文件：**

![SouthEast 1][]

**3，看到表的数据文件以及结构文件都存在**

然后去找$MYSQL\_HOME/share/mysql\_system\_tables.sql，search到建表语句

![SouthEast 2][]

打开mysql\_system\_tables.sql，找到sql，然后执行：

mysql> CREATETABLE IF NOT EXISTS innodb_index_stats (
    
    -> database_name VARCHAR(64) NOT NULL,
    
    -> table_name VARCHAR(64) NOT NULL,
    
    -> index_name VARCHAR(64) NOT NULL,
    
    -> last_update TIMESTAMP NOT NULL NOTNULL DEFAULT CURRENT_TIMESTAMP ON UPDATE CURRENT_TIMESTAMP,
    
    -> stat_name VARCHAR(64) NOT NULL,
    
    -> stat_value BIGINT UNSIGNED NOT NULL,
    
    -> sample_size BIGINT UNSIGNED,
    
    -> stat_description VARCHAR(1024) NOT NULL,
    
    -> PRIMARY KEY (database_name,table_name, index_name, stat_name)
    
    -> ) ENGINE=INNODB DEFAULT CHARSET=utf8COLLATE=utf8_bin STATS_PERSISTENT=0;
    
    ERROR 1146(42S02): Table 'mysql.innodb_index_stats' doesn't exist
    
    mysql>
    
    mysql>

还报错Table 'mysql.innodb\_index\_stats' doesn'texist，可能是那个判断导致，去掉判断试试：

mysql> CREATETABLE innodb_index_stats (
    
    -> database_name VARCHAR(64) NOT NULL,
    
    -> table_name VARCHAR(64) NOT NULL,
    
    -> index_name VARCHAR(64) NOT NULL,
    
    -> last_update TIMESTAMP NOT NULL NOTNULL DEFAULT CURRENT_TIMESTAMP ON UPDATE CURRENT_TIMESTAMP,
    
    -> stat_name VARCHAR(64) NOT NULL,
    
    -> stat_value BIGINT UNSIGNED NOT NULL,
    
    -> sample_size BIGINT UNSIGNED,
    
    -> stat_description VARCHAR(1024) NOT NULL,
    
    -> PRIMARY KEY (database_name,table_name, index_name, stat_name)
    
    -> ) ENGINE=INNODB DEFAULT CHARSET=utf8COLLATE=utf8_bin STATS_PERSISTENT=0;
    
    ERROR 1146(42S02): Table 'mysql.innodb_index_stats' doesn't exist

诡异，不存在还不让create了，是否原来的数据文件存在不过坏了，所以create的时候就报了这样一个诡异的错误呢？

**4，去数据库目录看下，果然文件是否已经存在了：**

[root@xxx mysql]# ll /home/data/mysql/data/mysql/innodb*
    
    -rw-rw----. 1mysql mysql 12982 4月 922:24 /home/data/mysql/data/mysql/innodb_index_stats.frm
    
    -rw-rw----. 1mysql mysql 180224 5月 6 10:38/home/data/mysql/data/mysql/innodb_index_stats.ibd
    
    -rw-rw----. 1mysql mysql 8830 4月 922:24 /home/data/mysql/data/mysql/innodb_table_stats.frm
    
    -rw-rw----. 1mysql mysql 98304 5月 610:38 /home/data/mysql/data/mysql/innodb_table_stats.ibd
    
    [root@xxx mysql]#

如果是myisam表还可以用命令修复一下，但是innnodb，就只好重启数据库试试，restart之后，进入mysql库：

mysql> descinnodb_index_stats;
    
    ERROR 1146(42S02): Table 'mysql.innodb_index_stats' doesn't exist

还是报错，那就只有drop操作：

mysql> droptable mysql.innodb_index_stats;
    
    ERROR 1051(42S02): Unknown table 'mysql.innodb_index_stats'
    
    mysql>
    
    mysql>

**5，RM操作删除掉旧的坏的数据表文件**

drop还是报错，最后看来只有一招了，rm -rf掉原来已经存在坏掉的不能加载的innodb\_index\_stats文件，再重新create了。

rm -rf/home/data/mysql/data/mysql/innodb*

rm后再登陆mysql执行create操作。

mysql> usemysql;
    
    Database changed
    
    mysql>
    
    mysql> CREATE TABLE innodb_index_stats (
    
    -> database_name VARCHAR(64) NOT NULL,
    
    -> table_name VARCHAR(64) NOT NULL,
    
    -> index_name VARCHAR(64) NOT NULL,
    
    -> last_update TIMESTAMP NOT NULL NOTNULL DEFAULT CURRENT_TIMESTAMP ON UPDATE CURRENT_TIMESTAMP,
    
    -> stat_name VARCHAR(64) NOT NULL,
    
    -> stat_value BIGINT UNSIGNED NOT NULL,
    
    -> sample_size BIGINT UNSIGNED,
    
    -> stat_description VARCHAR(1024) NOT NULL,
    
    -> PRIMARY KEY (database_name,table_name, index_name, stat_name)
    
    -> ) ENGINE=INNODB DEFAULT CHARSET=utf8 COLLATE=utf8_binSTATS_PERSISTENT=0;
    
    Query OK, 0 rowsaffected (0.02 sec)

**创建innodb\_index\_stats成功了。最后执行原来的mysqldump备份操作，一切正常。**
