摘要：Oracle数据库与MySQL数据库的区别是本文我们主要要介绍的内容，接下来我们就开始介绍这部分内容，希望能够对您有所帮助。
Oracle与MySQL的区别：
1.在Oracle中用select * from all_users显示所有的用户，而在MYSQL中显示所有数据库的命令是show databases.对于我的理解，Oracle项目来说一个项目就应该有一个用户和其对应的表空间，而MYSQL项目中也应该有个用户和一个库。在ORACLE（db2也一样）中表空间是文件系统中的物理容器的逻辑表示，视图、触发器和存储过程也可以保存在表空间中。而MYSQL并没有使用表空间来进行管理。
2.查询当前所有的表。ORACLE: select * from tab,MYSQL:show tables.
3.改变连接用户（库）。ORACLE:conn 用户名/密码@主机字符串，MYSQL:use 库名。
4.显示当前连接用户（库）。ORACLE:show user,MYSQL:connect.
5.执行外部脚本命令。ORACLE:@a.sql,MYSQL:source a.sql.
以上就是关于Oracle数据库与MySQL数据库的几点区别的对比，希望本次的介绍能够对您有所收获！
