免费版和商业版Mysql的区别是什么?

是不是商业版也可以象免费版一样使用,代码完全公开呢,只是多了技术支持?

谢谢!

我现在需要将Mysql安装到固定的路径中,所以担心商业版本上会有一些限制.

而且在官网上看到,好象Mysql还有一种版本是Mysql Enterprise.而且我现在也不清楚公司到底买了哪一个版本.

所以想来确认一下,免费版和商业版在使用上会有什么不同之处吗?

I have done it. but I am still not sure about the difference.

Do u mean the information below:

MySQL AB provides its software (database server, connectors, tools) under a number of flexible licenses, designed to meet the usage and distribution requirements of different types of users:
For Open Source Projects:

    * If you are developing and distributing open source applications under the GPL License, then you are free to use MySQL under the GPL License. More Info »

可恶的
商业版本带服务,而且你使用MySQL里面所编写的东西不遵循GPL协议,即可以不公开。
我记得是如此。

那我可以对商业版本中的代码进行改动吗?

比如决定它的安装目录?

我看了付费版本也包括两种:
一种是嵌入式式的,提供给OEM厂商的
还有一种是Enterprise得

是不是说:如果买的是Enterprise版本的,就不能对源代码做改动了

可恶的

可以更改的,我之前没说清楚,商业版是我们所写的东西(比如优化、存储等资料能够不遵循GPL协议,保有版权)
我记得是这样,具体你去看下官方手册吧。

哦,非常感谢!
