mysql数据库修改数据表引擎的方法_MySQL
bitsCN.com
对于MySQL数据库，如果你要使用事务以及行级锁就必须使用INNODB引擎。如果你要使用全文索引，那必须使用myisam。 INNODB的实用性，安全性，稳定性更高但是效率比MYISAM稍差，但是有的功能是MYISAM没有的。修改MySQL的引擎为INNODB，可以使用外键，事务等功能，性能高。
查看数据表的状态
SHOW TABLE STATUS FROM sites WHERE NAME='site';
SHOW TABLE STATUS FROM db_name WHERE NAME='table_name';
更改表的引擎
alter table table_name engine=innodb;
alter table table_name engine=myisam;
