如何查看MySQL的当前存储引擎？

一般情况下，mysql会默认提供多种存储引擎,你可以通过下面的查看:

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;

视频讲解的是mysql数据库中存储引擎的知识，使用命令的方式查看当前数据库服务器用的什么存储引擎。本视频的目的在于一方面学习熟悉命令，另一方面为后续的学习存储引擎知识做铺垫。

mysql> show engines;
