InnoDB: Error: Table "mysql"."innodb_table_stats" not found.

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:

InnoDB: Error: Table "mysql"."innodb_table_stats" not found.

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:

 InnoDB: Error: Table "mysql"."innodb_table_stats" not found.

 

 

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

InnoDB: Error: Table "mysql"."innodb_table_stats" not found.

 

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。
