MySQL - 將表格引擎從 innoDB 更改為 MyISAM?
讓我們先建立一個表 -
mysql> create table DemoTable1982 ( StudentId int , StudentName varchar(20), StudentAge int ); Query OK, 0 rows affected (0.00 sec)
讓我們檢查一下表引擎型別 -
mysql> show create table DemoTable1982;
這會產生以下輸出 -
+---------------+---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------+ | 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)
以下是可以將表引擎從 innoDB 更改為 MyISAM 的查詢 -
mysql> alter table DemoTable1982 ENGINE='MyISAM'; Query OK, 0 rows affected (0.00 sec) Records: 0 Duplicates: 0 Warnings: 0
現在讓我們檢查一下表引擎的型別 -
mysql> show create table DemoTable1982;
這會產生以下輸出 -
+---------------+---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------+ | 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)
