Hi Scott,

Thanks for writing!

This issue can be difficult for some developers because the MySQL licensing model is different than the model used by most commercial database management system (DBMS) vendors.

With most commercial DMBS, the client has a license for the DBMS. It is up to the client to ensure that they have the correct licensing for the DBMS and is no concern of developers who build applications for the DBMS.

In the case of MySQL, when a developer wishes to do something that is not permitted by the GPL license, they need a commercial license and must pass the cost on to their customers.

For developers building inexpensive proprietary applications, this model is less than optimal. To help overcome these problems, there are several major approaches that we take.

First, think about making your application Free Software or Open Source. You can use MySQL without cost then (in most cases), and can usually still sell your application (and any services to support it) at a fair rate.

Second, we have a program that allows developers to freely embed a commercially-licensed MySQL client in their application (be it a value-add GUI tool, a widget management suite or a home inventory system). The client will only talk to a commercially licensed MySQL server. This approach works well for some developers, but has overhead. In general, it is only suitable for applications with a high distribution volume. If you are curious about this option drop by http://www.mysql.com/company/contact/ and send us a message or give us a call.

The final approach is very simple. If you are a small vendor or independent developer who needs a pricing break to make your application viable, just write a letter to community@mysql.com that outlines your situation and needs. We will work to try and arrange pricing that works for your application. In the letter, please provide us with information on what your application does, what you want to charge for it, how many you hope to sell, and so on.

Please let me know if you have other questions (and, if appropriate, please keep it on the forum so that others can benefit from the discussion!)

Thanks!
