在 MySQL 中將表格從 MyISAM 轉換為 INNODB？

為此，請使用 ALTER 指令。讓我們先建立一個表。預設引擎設定為「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;
Query OK, 0 rows affected (0.67 sec)

以下是將表從MyISAM 轉換為INNODB 的查詢-

mysql> alter table DemoTable ENGINE=InnoDB;
Query OK, 0 rows affected (1.97 sec)
Records: 0 Duplicates: 0 Warnings: 0

現在讓我們檢查表的狀態-

mysql> show create table DemoTable;

輸出

這將產生以下輸出，將更新後的引擎顯示為InnoDB -

+--------------+-------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------+
