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 |
+---------------+---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------+
