1 查看系统支持的存储引擎

show engines;

2 查看表使用的存储引擎

两种方法:

a、show table status from db_name where;

b、show create table table_name;

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;

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

linux
