Question

可能重复：
How can I check MySQL engine type for a specific table?

假设用户是一个跟随命令的表，则不会显示用户表是MyISAM还是Innodb。

desc users;

如何找到用户表的类型？

Answer 1

您可以使用SHOW TABLE STATUS查看表信息。

SHOW TABLE STATUS WHERE `Name` = 'my_table';

只需检查返回数据集中Engine列的值，即可知道该表正在使用哪个引擎。

Answer 2

SELECT ENGINE
FROM INFORMATION_SCHEMA.TABLES 

WHERE TABLE_NAME='your_table_name'
AND   TABLE_SCHEMA='your_database_name';
-- or use TABLE_SCHEMA=DATABASE() if you have a default one.

Answer 3

您可以使用SHOW CREATE TABLE并在回复中查找ENGINE部分。

SHOW CREATE TABLE users;

示例：

CREATE TABLE innodb_table (id int, value int) ENGINE=INNODB;
CREATE TABLE myisam_table (id int, value int) ENGINE=MYISAM;
CREATE TABLE default_table (id int, value int);

innodb_table的结果：

SHOW CREATE TABLE innodb_table;
+--------------+----------------------------------------------------------------------------------------------------------------------------------+
| Table        | Create Table                                                                                                                     |
+--------------+----------------------------------------------------------------------------------------------------------------------------------+
| innodb_table | CREATE TABLE `innodb_table` (
  `id` int(11) DEFAULT NULL,
  `value` int(11) DEFAULT NULL
) ENGINE=InnoDB DEFAULT CHARSET=latin1 |
+--------------+----------------------------------------------------------------------------------------------------------------------------------+
1 row in set (0.00 sec)

myisam_table的结果：

SHOW CREATE TABLE myisam_table;
+--------------+----------------------------------------------------------------------------------------------------------------------------------+
| Table        | Create Table                                                                                                                     |
+--------------+----------------------------------------------------------------------------------------------------------------------------------+
| myisam_table | CREATE TABLE `myisam_table` (
  `id` int(11) DEFAULT NULL,
  `value` int(11) DEFAULT NULL
) ENGINE=MyISAM DEFAULT CHARSET=latin1 |
+--------------+----------------------------------------------------------------------------------------------------------------------------------+
1 row in set (0.00 sec)

default_table的结果：

SHOW CREATE TABLE default_table;
+---------------+-----------------------------------------------------------------------------------------------------------------------------------+
| Table         | Create Table                                                                                                                      |
+---------------+-----------------------------------------------------------------------------------------------------------------------------------+
| default_table | CREATE TABLE `default_table` (
  `id` int(11) DEFAULT NULL,
  `value` int(11) DEFAULT NULL
) ENGINE=MyISAM DEFAULT CHARSET=latin1 |

1 row in set (0.00 sec)
