将表从MyISAM转换为MySQL中的INNODB？
为此，请使用ALTER命令。让我们首先创建一个表。默认引擎设置为“MYISAM”-
mysql> create table DemoTable -> ( -> ClientId int NOT NULL AUTO_INCREMENT, -> ClientName varchar(100), -> ClientAge int, -> ClientCountryName varchar(100), -> isMarried boolean, -> PRIMARY KEY(ClientId) -> )ENGINE=MyISAM;
以下是将表从MyISAM转换为INNODB的查询-
mysql> alter table DemoTable ENGINE=InnoDB; Records: 0 Duplicates: 0 Warnings: 0
现在让我们检查表的状态-
mysql> show create table DemoTable;
输出结果
这将产生以下输出，将更新的ENGINE显示为InnoDB-
+--------------+-------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------+ | Table | Create Table | +--------------+-------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------+ | DemoTable | CREATE TABLE `DemoTable` (`ClientId` int(11) NOT NULL AUTO_INCREMENT, `ClientName` varchar(100) COLLATE utf8_unicode_ci DEFAULT NULL, `ClientAge` int(11) DEFAULT NULL, `ClientCountryName` varchar(100) COLLATE utf8_unicode_ci DEFAULT NULL, `isMarried` tinyint(1) DEFAULT NULL, PRIMARY KEY (`ClientId`) ) ENGINE=InnoDB DEFAULT CHARSET=utf8 COLLATE=utf8_unicode_ci | +--------------+-------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------+ 1 row in set (0.00 sec)
