查看MySQL提供什么存储引擎:

mysql> show engines;

查看MySQL当前默认的存储引擎:

mysql> show variables like '%storage_engine%';+----------------------------------+--------+| Variable_name                    | Value  |+----------------------------------+--------+| default_storage_engine           | InnoDB || default_tmp_storage_engine       | InnoDB || disabled_storage_engines         |        || internal_tmp_disk_storage_engine | InnoDB |+----------------------------------+--------+4 rows in set, 1 warning (0.01 sec)

创建表：

mysql> create table NEWS (    ->        ID integer not null auto_increment,    ->         AUTHOR varchar(255),    ->         CONTENT varchar(255),    ->         CREATEDATE datetime,    ->         primary key (ID)    ->     ) ;Query OK, 0 rows affected (0.04 sec)

 

你要看 news 表用了什么引擎(在显示结果里参数engine后面的就表示该表当前用的存储引擎):

mysql> show create table news;1 row in set (0.01 sec)

 

将 news 表修为InnoDB存储引擎(也可以此命令将InnoDB换为MyISAM)：

mysql> ALTER TABLE news ENGINE=INNODB;
