Can I use InnoDB and MyISAM tables in a single database in MySQL?
Yes, you can use InnoDB and MyISAM tables in one database or combine both of them in a single database. This is the recommended way.
Here is the demo of both MyISAM and InnoDB in a one database. The following is the database and both the table types InnoDB and MyISAM. The query to create a database is as follows −
mysql> create database BothInnoDBandMyISAM; Query OK, 1 row affected (0.20 sec) mysql> use BothInnoDBandMyISAM; Database changed
I have a database with name ‘BothInnoDBandMyISAM’.
First the table has engine type InnoDB. The query to create a table with engine InnoDB is as follows −
mysql> create table Student -> ( -> StudentId int, -> StudentName varchar(20) -> )ENGINE=InnoDB; Query OK, 0 rows affected (1.20 sec)
The second table has engine type MyISAM. The query to create a table with engine MyISAM is as follows −
mysql> create table Employee -> ( -> EmployeeId int, -> EmployeeName varchar(30) -> )ENGINE=MyISAM; Query OK, 0 rows affected (0.28 sec)
Here is the query to check the engine type from the same database. The query is as follows for the first table.
mysql> select engine from information_schema.tables where table_name='Student' and table_schema='BothInnoDBandMyISAM';
The following is the output −
+--------+ | ENGINE | +--------+ | InnoDB | +--------+ 1 row in set (0.00 sec)
Here is the query to check table engine type from the same database. The query is as follows for the second table.
mysql> select engine from information_schema.tables where table_name='Employee' and table_schema='BothInnoDBandMyISAM';
The following is the output −
+--------+ | ENGINE | +--------+ | MyISAM | +--------+ 1 row in set (0.00 sec)
