1、查看mysql提供的引擎。

MariaDB [(none)]> show engines;

| Engine             | Support | Comment                                                                    | Transactions | XA   | Savepoints |
+--------------------+---------+----------------------------------------------------------------------------+--------------+------+------------+

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

2 rows in set (0.00 sec)

3、查看某个表的引擎。

MariaDB [(none)]> show create table 表名;
