MySQL has two different types of licensing agreements.
Open Source license (GNU) and the other more applicable to developers is their Commercial license. Below are excerpts from the MySQL documentation.
NOTE: Since Mertech’s drivers are not open source; anyone using our drivers along with MySQL must purchase a Commercial license.
GNU
The MySQL software is released under the GNU General Public License (GPL), which probably is the best-known Open Source license. The formal terms of the GPL license can be found at http://www.gnu.org/licenses/. See also http://www.gnu.org/licenses/gpl-faq.html and http://www.gnu.org/philosophy/enforcing-gpl.html. Since the MySQL software is released under the GPL, it may often be used for free, but for certain uses you may want or need to buy commercial licenses from MySQL AB at https://order.mysql.com/. Older versions of MySQL (3.22 and earlier) are subject to a stricter license. See the documentation of the specific version for information.
Please note that the use of the MySQL software under commercial license, GPL, or the old MySQL license does not automatically give you the right to use MySQL AB trademarks. See MySQL documentation section 1.4.4 MySQL AB Logos and Trademarks.
