MySQL Commercial License for OEMs, ISVs and VARs

Sun provides its MySQL database server and MySQL Client Libraries under a dual license model designed to meet the development and distribution needs of both commercial distributors (such as OEMs, ISVs and VARs) and open source projects.

For OEMs, ISVs, VARs and Other Distributors of Commercial Applications:

OEMs, ISVs, VARs and other distributors that combine and distribute commercially licensed software with MySQL software and do not wish to distribute the source code for the commercially licensed software under version 2 of the GNU General Public License (the "GPL") must enter into a commercial license agreement with Sun.

For Open Source Projects and Other Developers of Open Source Applications:

For developers of Free Open Source Software ("FOSS") applications under the GPL that want to combine and distribute those FOSS applications with MySQL software, Sun's MySQL open source software licensed under the GPL is the best option.

Es decir se ofrecen dos modalidades de licenciamiento, una bajo la GNU GPL para cualquier uso compatible con esta licencia, y la otra para las empresas que quieran incorporarlo en sus productos comerciales y estos deben comprar a Sun una licencia específica que les permita este uso.
