Innobase Oy 专门向 Sun/MySQL 提供 InnoDB,Sun/MySQL 在其产品中分发和支持 InnoDB。 InnoDB 包含在 MySQL Enterprise Server 中的开源 GNU 公共许可证 (GPL) V2 下,适合广泛的用户。 MySQL 社区版同样可以根据 GPLv2 条款以开源方式获得,也包括 InnoDB。
UPDATE. Sorry, I got it wrong first. If you are not distributing your website's code, then no, you don't need to buy a license. GPL only restricts redistribution, not use.
Innobase Oy provides InnoDB exclusively to Sun/MySQL, which distributes and supports InnoDB within its product offerings. InnoDB is included under the open source GNU Public License (GPL) V2 in the MySQL Enterprise Server and is suitable for a broad range of users. The MySQL Community Edition, which is likewise is available in open source under the terms of the GPLv2, also includes InnoDB.
From my understanding you don't have to purchase a commercial license if you want to use MySQL for commercial purposes. Purchasing a license gives you enterprise support from the MySQL team and they help you with optimization and stuff like that. Look at the comparison chart here:
PostgreSQL has no commercial version and is much safer (legally) to use than MySQL, plus it very similar to Oracle Pl/SQL so the skills needed for it are almost the same as Oracle and easy to find.
To be safe I would not use MySQL unless I purchased a license.

更新。抱歉,我先说错了。如果您不分发网站的代码,那么不需要,您不需要购买许可证。 GPL 只限制重新分发,不限制使用。

PostgreSQL 完全免费,是 MySQL 的合适替代品。
据我了解,您使用 MySQL 的方式是在免费许可证内,但我对此并不乐观。
PostgreSQL is completely free and is a suitable replacement for MySQL.
From what I understand the way you are using MySQL is within the free license, but I'm not positive on that one.
据我了解,如果您想将 MySQL 用于商业目的,则不必购买商业许可证。购买许可证可以为您提供来自 MySQL 团队的企业支持,他们可以帮助您进行优化等工作。看一下这里的比较图:

Firebird 可能是一个非常好的选择,而且它是免费的

PostgreSQL没有商业版本,使用起来比MySQL安全(合法)得多,而且它与Oracle Pl/SQL非常相似,因此所需的技能与Oracle几乎相同并且很容易找到。
为了安全起见,除非购买了许可证,否则我不会使用 MySQL。
