您可以借助alter命令更改表引擎。语法如下-
alter table yourTableName ENGINE = yourEngineName;
为了理解上述语法,让我们使用引擎MyISAM创建一个表。以后您可以更改任何其他引擎。以下是创建表的查询。
mysql> create table ChangeEngineTableDemo −> ( −> MovieId int, −> MovieName varchar(100), −> IsPopular bool −> )ENGINE = 'MyISAM';
查看上面的查询,表引擎是MyISAM,现在您可以将其更改为任何其他引擎。在这里,我们将更改引擎类型InnoDB。更改引擎类型的查询如下-
mysql> alter table ChangeEngineTableDemo ENGINE = InnoDB; Records: 0 Duplicates: 0 Warnings: 0
要在show命令的帮助下检查引擎类型是否已更改,以下是查询-
mysql> show create table ChangeEngineTableDemo;
以下是输出-
