Converting table from MyISAM to INNODB in MySQL?
For this, use ALTER command. Let us first create a table. The default engine is set as“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)
Following is the query to convert table from MyISAM to INNODB −
mysql> alter table DemoTable ENGINE=InnoDB; Query OK, 0 rows affected (1.97 sec) Records: 0 Duplicates: 0 Warnings: 0
Let us now check the status of table −
mysql> show create table DemoTable;
Output
This will produce the following output displaying the updated ENGINE as InnoDB −
