A command-line interface is a way of interacting with a computer program in which the user sends commands to the program by typing consecutive lines of text (command lines). MySQL comes with many command-line tools, whose main interface is the MySQL client.   MySQL AB welcomes references to the MySQL database, but note that the word MySQL is a registered trademark of MySQL AB. For this reason, you should add the trademark symbol () to the first or most prominent use of the word MySQL in the text and, if necessary, indicate that MySQL is a trademark ™ of MySQL AB.
For more information, please see our Trademark Policy at www.mysql.com/company/trademark.html. Older versions of MySQL (3.22 and earlier) are subject to a stricter license (www.mysql.com/support/arrangements/mypl.html). For more information, see the documentation for each release. For other open source projects that do not use the GPL, MySQL has set the FLOSS or FOSS license exception. FLOSS stands for Free and Open Source Software. (On the MySQL website, the exception is often abbreviated to FOSS.) Open source projects that exist under a license that is part of the FOSS exception are allowed to incorporate the MySQL client library into their code without the restrictions of the GPL. More details on these license exceptions can be found here: www.mysql.com/company/legal/licensing/faq.html www.mysql.com/company/legal/licensing/foss-exception.html Use the logo you need as it appears on the www.mysql.com/ website. You can customize it to suit your needs, but you can`t change the colors or drawings, or change the graphics in any way. Because MySQL software is released under the GPL, it is often free to use, but for certain purposes you may want or need to purchase commercial licenses of MySQL AB from order.mysql.com/. Please firstname.lastname@example.org send an email for more information or if you are interested in a translation. To purchase commercial licenses and support, please visit the ordering section of our website in order.mysql.com/.
If you have special licensing requirements or if Internet access is limited, please contact our sales representatives in email@example.com. We have designed a number of special conditional use logos that can be downloaded from our website in www.mysql.com/downloads/logos.html and used on third party websites without written permission from MySQL AB. The use of these logos is not totally unlimited, but, as the name suggests, our trademark policy, which is also available on our website. You should read the trademark policy if you want to use it. The requirements are basic: many MySQL database users want to display the MySQL AB dolphin logo on their websites, books, or packaged products. We welcome and encourage this, although it should be noted that the word MySQL and the MySQL dolphin logo are trademarks of MySQL AB and may only be used as stated in our www.mysql.com/company/trademark.html Brand Policy. The GNU getopt library is licensed under the GNU Lesser General Public License. See www.mysql.com/doc/L/G/LGPL-license.html. You can find detailed information about our various support options in order.mysql.com/ where support contracts can also be ordered online. If you have limited access to the Internet, please contact our sales representatives in firstname.lastname@example.org. For legal and business reasons, we need to monitor the use of MySQL trademarks on products, books, etc.
We generally charge a fee for displaying MySQL AB logos on commercial products, as we consider it appropriate that a portion of the revenue be returned to fund the development of the MySQL database. Tip: For more information about MySQL licensing, see the following pages: www.mysql.com/company/legal/licensing/ www.mysql.com/network/ order.mysql.com/ shop.mysql.com/?sub=vt&id=software If you want to redistribute mySQL with a commercial product, check its legal aspect. I think most companies get around this problem by installing the mySQL server separately. I will not publish the source code of my software, and it will be a commercial application. Can I use MySQL without paying MySQL fees? If it`s illegal, suggests an alternative database?. In April 2009, Oracle Corporation entered into an agreement to acquire Sun Microsystems, then the owner of MySQL`s copyright and trademark. Sun`s board of directors unanimously approved the deal. It was also approved by Sun shareholders and the U.S.
government on August 20, 2009.  On December 14, 2009, Oracle committed to continue improving MySQL as it had done for the previous four years. Do not use the trademark in any manner that infringes MySQL AB or the trademark value of MySQL AB. We reserve the right to revoke the right to use the MySQL AB trademark. Tip: For more information about the idea of open source, the full text of the GPL, and explanations, see the following addresses: C-API: Application Interface for C Programming Connector/C++: Library for C++ Programming Connector/J: JDBC driver for Java programming Connector/MXJ: J2EE MBean driver for Java programming Connector/NET:. NET driver mainly for programming on Windows Connector/ODB: ODBC driver for all programming on Windows In addition to the current MySQL server, the MySQL company offers client libraries necessary for the development of application programs (there are additional drivers developed outside the MySQL company, such as the PHP driver): I don`t know what the GPL is (the license, under which mySQL is distributed) means binding against closed source software for applications that are not directly related to mySQL, but ship with mySQL client libraries. Do they have to be open source? If anyone wishes to shed light on this issue in a separate reply or comment, I would be very interested. If your use of MySQL database software does not require a commercial license, we recommend that you continue to purchase support from MySQL AB.
In this way, you contribute to MySQL development and also get immediate benefits. See section 1.4.1. This documentation is NOT distributed under the GPL.

If you find any errors, please report them to us in writing. The MySQL dolphin logo was designed in 2001 by the Finnish advertising agency Priority. The dolphin was chosen as the appropriate symbol for the MySQL database because it is an intelligent, fast and skinny animal that sails effortlessly through oceans of data. We also love dolphins. When using some storage engines other than InnoDB`s default engines, MySQL does not comply with the full SQL standard for some of the features implemented, including foreign key references.  Verification constraints are parsed but ignored by all storage engines prior to MySQL version 8.0.15.   If you want to support the evolution of the MySQL database, even if you do not formally need a commercial license. Purchasing support directly from MySQL AB is another great way to contribute to the development of MySQL software, with immediate benefits for you.
See section 1.4.1. This is the reference manual for the MySQL database system, version 8.0, to version 8.0.24. The differences between minor versions of MySQL 8.0 are indicated in this text by reference to version numbers (8.0.x). License information can be found in the legal notice. MySQL Utilities is a set of utilities designed for general maintenance and management tasks. Originally included as part of MySQL Workbench, the utilities are a standalone download available from Oracle. Oracle deploys its MySQL database server and MySQL client libraries under a dual-licensing model designed to meet the development and sales needs of commercial distributors (such as OEMs, ISVs, and value-added resellers) and open source projects. MySQL Workbench is the integrated environment for MySQL. It was developed by MySQL AB and allows users to manage MySQL databases graphically and visually design database structures. The GPL is contagious in the sense that if a program is associated with a GPL program, the resulting product must also be released under the GPL so that you do not violate the license terms and lose your right to use the GPL program as a whole. For more information about Oracle`s commitment to accessibility, see www.oracle.com/corporate/accessibility/ on the Oracle Accessibility Program website.
