MySQL-将表引擎从innoDB更改为MyISAM？
让我们首先创建一个表-
mysql> create table DemoTable1982 ( StudentId int , StudentName varchar(20), StudentAge int );
让我们检查表格引擎类型-
mysql> show create table DemoTable1982;
这将产生以下输出-
+---------------+---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------+ | Table | Create Table | +---------------+---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------+ | DemoTable1982 | CREATE TABLE `demotable1982` (`StudentId` int(11) DEFAULT NULL, `StudentName` varchar(20) COLLATE utf8_unicode_ci DEFAULT NULL, `StudentAge` int(11) DEFAULT NULL ) ENGINE=InnoDB DEFAULT CHARSET=utf8 COLLATE=utf8_unicode_ci | +---------------+---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------+ 1 row in set (0.00 sec)
这是将表引擎从innoDB更改为MyISAM的查询-
mysql> alter table DemoTable1982 ENGINE='MyISAM'; Records: 0 Duplicates: 0 Warnings: 0
现在让我们检查表引擎类型-
mysql> show create table DemoTable1982;
这将产生以下输出-
+---------------+---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------+ | Table | Create Table | +---------------+---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------+ | DemoTable1982 | CREATE TABLE `demotable1982` ( `StudentId` int(11) DEFAULT NULL, `StudentName` varchar(20) COLLATE utf8_unicode_ci DEFAULT NULL, `StudentAge` int(11) DEFAULT NULL ) ENGINE=MyISAM DEFAULT CHARSET=utf8 COLLATE=utf8_unicode_ci | +---------------+---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------+ 1 row in set (0.00 sec)
