如何确认目前的你所用的MYSQL数据库的引擎
看你的mysql现在已提供什么存储引擎:
mysql> show engines;
看你的mysql当前默认的存储引擎:
mysql> show variables like '%storage_engine%';
你要看某个表用了什么引擎(在显示结果里参数engine后面的就表示该表当前用的存储引擎):
mysql> show create table 表名;
mysql> show variables like '%storage_engine%';
+----------------------------+--------+
| Variable_name | Value |
+----------------------------+--------+
| default_storage_engine | InnoDB |
| default_tmp_storage_engine | InnoDB |
| storage_engine | InnoDB |

下面是执行了show create table 表名;之后在ENGINE后可以看到用的是InnoDB引擎。
