mysqlmysqli database更新于 2024/12/8 4:28:17
首先我们创建一个表 −
mysql> create table DemoTable1982 ( StudentId int , StudentName varchar(20), StudentAge int ); Query OK, 0 rows affected (0.00 sec)
Let us check the table engine type -
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)
以下是将表引擎从 innoDB 更改为 MyISAM − 的查询
mysql> alter table DemoTable1982 ENGINE='MyISAM'; Query OK, 0 rows affected (0.00 sec) 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)
