8 rows in set (0.00 sec)
2 查看表使用的存储引擎
两种方法：
a、show table status from db_name where name='table_name';
如：
mysql> show table status from test where name='user' \G
*************************** 1. row ***************************
Name: user
Engine: InnoDB
Version: 10
Row_format: Compact
Rows: 3
Avg_row_length: 5461
Data_length: 16384
Max_data_length: 0
Index_length: 0
Data_free: 4194304
Auto_increment: NULL
Create_time: 2013-11-01 09:24:24
Update_time: NULL
Check_time: NULL
Collation: gb2312_chinese_ci
Checksum: NULL
Create_options:
Comment:
1 row in set (0.00 sec)
b、show create table table_name;
如：
mysql> show create table user \G
*************************** 1. row ***************************
Table: user
Create Table: CREATE TABLE `user` (
`id` int(11) NOT NULL,
`name` varchar(50) NOT NULL,
`age` int(11) NOT NULL,
`sex` varchar(20) NOT NULL
) ENGINE=InnoDB DEFAULT CHARSET=gb2312
1 row in set (0.00 sec)
如果显示的格式不好看，可以用\G代替行尾分号
有人说用第二种方法不准确，我试了下，关闭掉原先默认的Innodb引擎后根本无法执行show create table table_name指令，因为之前建的是Innodb表，关掉后默认用MyISAM引擎，导致Innodb表数据无法被正确读取。
3 修改表引擎方法
alter table table_name engine=innodb;
如：
mysql> alter table user engine=InnoDB;
Query OK, 3 rows affected (0.40 sec)
Records: 3 Duplicates: 0 Warnings: 0
mysql> show table status from test where name='user' \G
*************************** 1. row ***************************
Name: user
Engine: InnoDB
Version: 10
Row_format: Compact
Rows: 3
Avg_row_length: 5461
Data_length: 16384
Max_data_length: 0
Index_length: 0
Data_free: 4194304
Auto_increment: NULL
Create_time: 2013-11-01 09:24:24
Update_time: NULL
Check_time: NULL
Collation: gb2312_chinese_ci
Checksum: NULL
Create_options:
Comment:
1 row in set (0.00 sec)
4 关闭Innodb引擎方法
关闭mysql服务： net stop mysql
找到mysql安装目录下的my.ini文件：
找到default-storage-engine=INNODB 改为default-storage-engine=MYISAM
找到#skip-innodb 改为skip-innodb
启动mysql服务：net start mysql
