MYSQL之查看及修改表使用的存储引擎

正确的方法：

show table status from db_name where name='table_name';

+------+--------+---------+------------+------+----------------+-------------+-----------------+

| Name | Engine | Version | Row_format | Rows | Avg_row_length | Data_length |

+---------+------------+------+----------------+-------------+-----------------+--------------+

|  t    | InnoDB |      10 | Compact    |    3 |           5461 |       16384 |               0 | 

+------+--------+---------+------------+------+----------------+-------------+-----------------+

不正确的方法：

show create table table_name;

+-------+-----------------------------------------------------------------------------------------+
| Table | Create Table                                                                                          |
+-------+-----------------------------------------------------------------------------------------+
| t     | CREATE TABLE `t` (
  `vc` varchar(1) DEFAULT NULL,
  `c` char(1) DEFAULT NULL,
  KEY `c` (`c`)
) ENGINE=InnoDB DEFAULT CHARSET=utf8 |
+-------+------------------------------------------------------------------------------------------+

如果mysqld没有启动对应的引擎如这里InnoDB，那么会使用默认的MYISAM引擎，所以不准确。

 

修改：

alter table table_name engine=innodb;

alter table table_name engine=myisam;
