千家信息网最后更新 2026年11月01日'mysql.column_stats' doesn't exist and Table 'mysql.index_stats' doesn'在生产库MariabDB中修改字段类型，提示如下错误：
Table 'mysql.column_stats' doesn't exist
Table 'mysql.index_stats' doesn't exist

MariaDB版本如下：
MariaDB [mysql]> select @@version;
+---------------------+
| @@version |
+---------------------+
| 10.0.12-MariaDB-log |
+---------------------+

连接mysql数据库检查表：
MariaDB [mysql]> show tables;
+---------------------------+
| Tables_in_mysql |
+---------------------------+
| columns_priv |
| db |
| event |
| func |
| general_log |

检查发现缺少提示错误的几张表，column_stats、index_stats、table_stats

解决方法：
在主库创建以上表：
CREATE TABLE IF NOT EXISTS `column_stats` (
`db_name` varchar(64) NOT NULL COMMENT 'Database the table is in.',
`table_name` varchar(64) NOT NULL COMMENT 'Table name.',
`column_name` varchar(64) NOT NULL COMMENT 'Name of the column.',
`min_value` varchar(255) DEFAULT NULL COMMENT 'Minimum value in the table (in text form).',
`max_value` varchar(255) NOT NULL COMMENT 'Maximum value in the table (in text form).',
`nulls_ratio` decimal(12,4) DEFAULT NULL COMMENT 'Fraction of NULL values (0 - no NULLs, 0.5 - half values are NULLs, 1 - all values are NULLs).',
`avg_length` decimal(12,4) DEFAULT NULL COMMENT 'Average length of column value, in bytes. Counted as if one ran SELECT AVG(LENGTH(col)). This doesn''t count NULL bytes, assumes endspace removal for CHAR(n), etc.',
`avg_frequency` decimal(12,4) DEFAULT NULL COMMENT 'Average number of records with the same value',
`hist_size` tinyint(3) unsigned DEFAULT NULL COMMENT 'Histogram size in bytes, from 0-255.',
`hist_type` enum('SINGLE_PREC_HB','DOUBLE_PREC_HB') DEFAULT NULL COMMENT 'Histogram type. See the histogram_type system variable.',
`histogram` varbinary(255) DEFAULT NULL
) ENGINE=InnoDB DEFAULT CHARSET=utf8;

CREATE TABLE IF NOT EXISTS `index_stats` (
`db_name` varchar(64) NOT NULL COMMENT 'Database the table is in.',
`table_name` varchar(64) NOT NULL COMMENT 'Table name',
`index_name` varchar(64) NOT NULL COMMENT 'Name of the index',
`prefix_arity` int(10) unsigned NOT NULL COMMENT 'Index prefix length. 1 for the first keypart, 2 for the first two, and so on. InnoDB''s extended keys are supported.',
`avg_frequency` decimal(12,4) DEFAULT NULL COMMENT 'Average number of records one will find for given values of (keypart1, keypart2, ..), provided the values will be found in the table.'
) ENGINE=InnoDB DEFAULT CHARSET=utf8;

CREATE TABLE IF NOT EXISTS `table_stats` (
`db_name` varchar(64) NOT NULL COMMENT 'Database the table is in .',
`table_name` varchar(64) NOT NULL COMMENT 'Table name.',
`cardinality` bigint(21) DEFAULT NULL COMMENT 'Number of records in the table.'
) ENGINE=InnoDB DEFAULT CHARSET=utf8;

ALTER TABLE `column_stats`
ADD PRIMARY KEY (`db_name`,`table_name`,`column_name`);

ALTER TABLE `index_stats`
ADD PRIMARY KEY (`db_name`,`table_name`,`index_name`,`prefix_arity`);

ALTER TABLE `table_stats`
ADD PRIMARY KEY (`db_name`,`table_name`);
