3 MySQL Licensing and Support
This chapter describes MySQL support and licensing
arrangements:
The copyrights under which MySQL is distributed
(see section 3.2 Copyrights Used by MySQL)
Sample situations illustrating when a license is required
(see section 3.3 Example Licensing Situations)
Support costs (see section 3.4 MySQL Licensing and Support Costs) and support benefits
(see section 3.5 Types of Commercial Support)
Commercial licensing costs
3.1 MySQL Licensing Policy
The formal terms of the GPL license can be found at section L GNU General Public License.
Basically, our licensing policy and interpretation of the GPL is as follows:
Note that older versions of MySQL are still using a more
strict license.
See the documentation for that version for more information. If you need a
commercial MySQL license, because the GPL license doesn't suit your
application, you can buy one at https://order.mysql.com/license.htmy.
For normal internal use, MySQL costs nothing. You do not have
to pay us if you do not want to.
A license is required if:
You link a part of the of MySQL that has a GPL Copyright to a
program that is not free software (embedded usage of the MySQL
server). In this case your application would also become GPL through the
clause in the GPL license that acts as a virus. By licensing MySQL
from us under a commercial license you will avoid this problem.
You have a commercial application that ONLY works with MySQL
and ships the application with the MySQL server. This is
because we view this as linking even if it is done over the network.
You have a distribution of MySQL and you don't provide the
source code for your copy of the MySQL server, as defined in
the GPL license.
A license is NOT required if:
You do not need a license to include the client code in commercial
programs. The client part of MySQL licensed with the
LGPL GNU Library General Public License. The mysql command-line
client includes code from the readline library that is under
the GPL.
If your use of MySQL does not require a license, but you
like MySQL and want to encourage further development, you are
certainly welcome to purchase a license or MySQL support anyway.
If you use MySQL in a commercial context such that you profit by
its use, we ask that you further the development of MySQL by
purchasing some level of support. We feel that if MySQL helps
your business, it is reasonable to ask that you help MySQL.
(Otherwise, if you ask us support questions, you are not only using for
free something into which we've put a lot a work, you're asking us to
provide free support, too.)
For circumstances under which a MySQL license is required, you
need a license per machine that runs the mysqld server. However,
a multiple-CPU machine counts as a single machine, and there is no
restriction on the number of MySQL servers that run on one
machine, or on the number of clients concurrently connected to a server
running on that machine!
If you have any questions as to whether or not a license is required for
your particular use of MySQL, please read this again and then
contact us. See section 3.4.2 Contact Information.
If you require a MySQL license, the easiest way to pay for it
is to use the license form on MySQL's secure server at
https://order.mysql.com/license.htmy. Other forms of payment are
discussed in section 3.4.1 Payment information.
3.2 Copyrights Used by MySQL
There are several different copyrights on the MySQL distribution:
The MySQL-specific source needed to build the
mysqlclient library is licensed under the LGPL and
programs in the `client' directory is GPL. Each file has a header
that shows which copyright is used for that file.
The client library and the (GNU getopt) library are covered
by the ``GNU LIBRARY GENERAL PUBLIC LICENSE.'' See section M GNU Library General Public License.
Some parts of the source (the regexp library) are covered
by a Berkeley-style copyright.
All the source in the server and the (GNU readline) library
is covered by the ``GNU GENERAL PUBLIC LICENSE.'' See section L GNU General Public License.
This is also available as the file `COPYING' in the distributions.
One goal is that the SQL client library should be free enough that it is
possible to add MySQL support into commercial products
without a license. For this reason, we chose the LGPL license for the
client code.
This means that you can use MySQL for free with any program that uses
any of the free software licenses. MySQL is also free for any end
user for his own or company usage.
However, if you use MySQL for something important to you, you may
want to help secure its development by purchasing licenses or a support
contract. See section 3.5 Types of Commercial Support.
3.2.1 Copyright Changes
Version 3.22 of MySQL is still using a more strict license.
See the documentation for that version for more information.
3.3 Example Licensing Situations
This section describes some situations illustrating whether or not you
must license the MySQL server. Generally these examples
involve providing MySQL as an integral part of a product.
Note that a single MySQL license covers any number of CPUs and
mysqld servers on a machine! There is no artificial limit on the
number of clients that connect to the server in any way.
3.3.1 Selling Products that use MySQL
To determine whether or not you need a MySQL license when
selling your application, you should ask whether the proper functioning
of your application is dependent on the use of MySQL and
whether you include the MySQL server with your product. There
are several cases to consider:
Does your application require MySQL to function properly?
If your product requires MySQL, you need a license for any
machine that runs the mysqld server. For example, if you've
designed your application around MySQL, then you've really made
a commercial product that requires the engine, so you need a license.
If your application does not require MySQL, you do not need to obtain
a license. For example, if using MySQL just adds some new optional
features to your product (such as adding logging to a database if
MySQL is used rather than logging to a text file), it should
fall within normal use, and a license would not be required.
In other words, you need a license if you sell a product designed
specifically for use with MySQL or that requires the
MySQL server to function at all. This is true whether or not
you provide MySQL for your client as part of your product
distribution.
It also depends on what you're doing for the client. Do you plan to
provide your client with detailed instructions on installing
MySQL with your software? Then your product may be contingent
on the use of MySQL; if so, you need to buy a license. If you
are simply tying into a database that you expect already to have been
installed by the time your software is purchased, then you probably
don't need a license.
3.3.2 ISP MySQL Services
Internet Service Providers (ISPs) often host MySQL servers for
their customers. With the GPL license this does not require a license.
On the other hand, we do encourage people to use ISPs that have
MySQL support, as this will give them the confidence that if
they have some problem with their MySQL installation, their ISP
will be able to solve the problem for them (in some cases with the help
from the MySQL development team).
All ISPs that want to keep themselves up-to-date should subscribe
to our announce mailing list so that they can be aware of fatal issues
that may be relevant for their MySQL installations.
Note that if the ISP doesn't have a license for MySQL,
it should give its customers at least read access to the source of
the MySQL installation so that its customer can verify that
it is patched correctly.
3.3.3 Running a Web Server Using MySQL
If you use MySQL in conjunction with a Web server on Unix, you
don't have to pay for a license.
This is true even if you run a commercial Web server that uses
MySQL, because you are not selling an embedded MySQL
version yourself. However, in this case we would like you to purchase
MySQL support, because MySQL is helping your enterprise.
3.4 MySQL Licensing and Support Costs
Our current license prices are shown below. These prices are now under
review because of the change to a GPL copyright. New prices and terms
will be posted on the MySQL web site at http://www.mysql.com/
as soon as they are ready.
All prices are in US Dollars. If you pay by credit card, the currency is
EURO (European Union Euro) so the prices will differ slightly.
Number of licenses Per copy Total
1 200 EURO 200 EURO
10 pack 150 EURO 1500 EURO
50 pack 120 EURO 6000 EURO
For high volume (OEM) purchases, the following prices apply:
Number of licenses Per copy Minimum Minimum payment
100-999 40 EURO 100 4000 EURO
1000-2499 25 EURO 200 5000 EURO
2500-4999 20 EURO 400 8000 EURO
For OEM purchases, you must act as the middle-man for eventual problems
or extension requests from your users. We also require that OEM
customers have at least an extended e-mail support contract. Note that
OEM licenses only apply for products where the user doesn't have direct
access to the MySQL server (embedded system). In other words,
the MySQL server should only be used with the application
that was supplied you.
If you have a low-margin, high-volume product, you can always talk to us
about other terms (for example, a percent of the sale price). If you do,
please be informative about your product, pricing, market, and any other
information that may be relevant.
A full-price license is not a support agreement and includes very minimal
support. This means that we try to answer any relevant questions. If the
answer is in the documentation, we will direct you to the appropriate
section. If you have not purchased a license or support, we probably will
not answer at all.
If you discover what we consider a real bug, we are likely to fix it in
any case. But if you pay for support we will notify you about the fix
status instead of just fixing it in a later release.
More comprehensive support is sold separately. Descriptions of what each
level of support includes are given in section 3.5 Types of Commercial Support. Costs for the various
types of commercial support are shown below. Support level prices are in
EURO (European Union Euro). One EURO is about 1.06 USD.
Type of support Cost per year
Basic e-mail support. See section 3.5.1 Basic E-mail Support. EURO 200
Extended e-mail support See section 3.5.2 Extended E-mail Support. EURO 1000
Login support See section 3.5.3 Login Support. EURO 2000
Extended login support See section 3.5.4 Extended Login Support. EURO 5000
Telephone support See section 3.5.5 Telephone Support. EURO 12000
You may upgrade from any lower level of support to a higher level of
support for the difference in price between the two support levels.
We do also provide telephone support (mostly emergency support but also
24/7 support). This support option doesn't however have a fixed price
but is negotiated for case to case. If you are interested in this option
you can email sales@mysql.com and tell us about your needs.
Note that as our sales staff is very busy, it may take some time until
your request is handled. Our support staff does however always answer
promptly to support questions!
3.4.1 Payment information
Currently we can take SWIFT payments, checks, or credit cards.
Payment should be made to:
Postgirot Bank AB
105 06 STOCKHOLM, SWEDEN

Specify: license and/or support and your name and e-mail address.
In Europe and Japan you can use EuroGiro (that should be less expensive) to the
same account.
If you want to pay by check, make it payable to ``MySQL Finland AB'' and
mail it to the address below:
MySQL AB
BOX 6434, Torsgatan 21
11382 STOCKHOLM, SWEDEN
If you want to pay by credit card over the Internet, you can use
MySQL AB's secure license form.
You can also print a copy of the license form, fill it in, and send it by fax
to:
+46-8-729 69 05
If you want us to bill you, you can use the license form and write ``bill
us'' in the comment field. You can also mail a message to
sales@mysql.com (not mysql@lists.mysql.com!)
with your company information and ask us to bill you.
3.4.2 Contact Information
For commercial licensing, please contact the MySQL licensing
team. The much preferred method is by e-mail to
licensing@mysql.com. Fax is also possible but handling of
these may take much longer (Fax +46-8-729 69 05).
If you represent a business that is interested in partnering with
MySQL, please send e-mail to partner@mysql.com.
For timely, precise answers to technical questions about MySQL
you should order one of our
support contracts.
MySQL support is provided by the MySQL developers so the
standard is extremely high.
If you are interested in placing a banner advertisement on our Web site,
please send e-mail to advertising@mysql.com.
If you are interested in any of the jobs listed in our
jobs section, please send e-mail
to jobs@mysql.com.
For general discussion amongst our many users, please direct your attention to
the appropriate mailing
list.
For general information inquires, please send e-mail to
info@mysql.com.
For questions or comments about the workings or content of the Web site,
please send e-mail to webmaster@mysql.com.
3.5 Types of Commercial Support
The following is true of all support options:
The support is per year.
We will fix, or provide a reasonable workaround for any repeatable bug.
We will give a reasonable effort to find and fix any other MySQL related bug.
The higher level of support contract the more effort we will put into finding
a solution to your problems.
The following is true for all support contracts except Basic email support:
For non-bug related things, like helping you optimize your queries or
your system, extending MySQL with new functionality, etc., we charge 200
EURO/hour, which is deducted from your support contract. In other words,
if you have login support (2000 EURO), you can expect us to work up to
10 hours to help you with things like this.
3.5.1 Basic E-mail Support
Basic e-mail support is a very inexpensive support option and should be
thought of more as a way to support our development of MySQL
than as a real support option. We at MySQL do give a lot of free
support in all the different MySQL lists, and the money we get from
basic e-mail support is largely used to make this possible.
At this support level, the MySQL mailing lists are the preferred
means of communication. Questions normally should be mailed to the primary
mailing list (mysql@lists.mysql.com) or one of the other regular
lists (for example, win32@lists.mysql.com for Windows-related
MySQL questions), as someone else already may have experienced and
solved the problem you have. See section 2.2 Asking Questions or Reporting Bugs.
However, by purchasing basic e-mail support, you also have access to the
support address mysql-support@mysql.com, which is not available
as part of the minimal support that you get by purchasing a MySQL
license. This means that for especially critical questions, you can
cross-post your message to mysql-support@mysql.com. (If the
message contains sensitive data, you should post only to
mysql-support@mysql.com.)
REMEMBER! to ALWAYS include your registration number and expiration
date when you send a message to mysql-support@mysql.com.
Note that if you have encountered a critical, repeatable bug, and follow
the rules outlined in the manual section of how to report bugs and send
it to bugs@lists.mysql.com, we promise to try to fix this as
soon as possible, regardless of your support level! See section 2.3 How to Report Bugs or Problems.
Basic e-mail support includes the following types of service:
If your question is already answered in the manual, we will inform you of the
correct section in which you can find the answer. If the answer is not in
the manual, we will point you in the right direction to solve your problem.
We guarantee a timely answer for your e-mail messages. We can't guarantee
that we can solve any problem, but at least you will receive an answer if we
can contact you by e-mail.
We will help with unexpected problems when you install MySQL from a
binary distribution on supported platforms. This level of support does not
cover installing MySQL from a source distribution. Supported
platforms are those for which MySQL is known to work.
See section 4.2 Operating Systems Supported by MySQL.
We will help you with bugs and missing features. Any bugs that are found are
fixed for the next MySQL release. If the bug is critical for
you, we will mail you a patch for it as soon the bug is fixed. Critical
bugs always have the highest priority for us, and we ensure that they are
fixed as soon as possible.
Your suggestions for the further development of MySQL will be
taken into consideration. By taking email support you have already
helped the further development of MySQL. If you want to have
more input, upgrade to a higher level of support.
If you want us to help optimize your system, you must upgrade to a
higher level of support.
3.5.2 Extended E-mail Support
Extended e-mail support includes everything in basic e-mail support with
these additions:
Your e-mail will be dealt with before mail from basic e-mail support users and
non-registered users.
Your suggestions for the further development of MySQL will
receive strong consideration. Simple extensions that suit the basic
goals of MySQL are implemented in a matter of days. By taking
extended e-mail support you have already helped the further development
of MySQL.
Typical situations that are covered by extended e-mail support are:
We will answer and (within reason) solve questions that relate to possible
bugs in MySQL. As soon as the bug is found and corrected, we
will mail a patch for it.
We will help with unexpected problems when you install MySQL from a
source or binary distribution on supported platforms.
We will answer questions about missing features and offer hints how to work
around them.
We will provide hints on optimizing mysqld for your situation.
You are allowed to influence the priority of items on the MySQL
TODO List. See section H MySQL and the future (The TODO). This will ensure that the features you really need
will be implemented sooner than they might be otherwise.
3.5.3 Login Support
Login support includes everything in extended e-mail support with
these additions:
Your e-mail will be dealt with even before e-mail from extended e-mail
support users.
Your suggestions for the further development of MySQL will
be taken into very high consideration. Realistic extensions that can be
implemented in a couple of hours and that suit the basic goals of
MySQL will be implemented as soon as possible.
If you have a very specific problem, we can try to log in on your system
to solve the problem ``in place.''
Like any database vendor, we can't guarantee that we can rescue any data from
crashed tables, but if the worst happens, we will help you rescue as much as
possible. MySQL has proven itself very reliable, but anything is
possible due to circumstances beyond our control (for example, if your system
crashes or someone kills the server by executing a kill -9 command).
We will provide hints on optimizing your system and your queries.
You are allowed to call a MySQL developer (in moderation) and
discuss your MySQL-related problems. This option is however
only to be used as a last result during an emergency after we have
failed to grasp the total problem with email. To make efficient
use of our time we need to first get all facts about the problem,
before talking on phone, to be able to work as efficiently as possible on
solving the problem.
3.5.4 Extended Login Support
Extended login support includes everything in login support with these
additions:
Your e-mail has the highest possible priority.
We will actively examine your system and help you optimize it and your
queries. We may also optimize and/or extend MySQL to better
suit your needs.
You may also request special extensions just for you. For example:
mysql> select MY_FUNC(col1,col2) from table;
We will provide a binary distribution of all important MySQL
releases for your system, as long as we can get an account on a
similar system. In the worst case, we may require access to your system
to be able to create a binary distribution.
If you can provide accommodations and pay for traveler fares, you can
even get a MySQL developer to visit you and offer you help with
your troubles. Extended login support entitles you to one personal
encounter per year, but we are always very flexible towards our
customers! If the visit takes 16 hours or more, the first 8 hours is
without charge. For the hours above 8 hours, you will be charged with a
rate that is at least 20 % less than our standard rates.
3.5.5 Telephone Support
Telephone support includes everything in extended login support with
these additions:
We will provide you with a dynamic web page showing the current list of
MySQL developers that you can phone when you have a critical
problem.
For non critical problem, you can request a MySQL developer to
phone back within 48 hours to discuss MySQL related issues.
3.5.6 Support for other table handlers
To get support for BDB tables, InnoDB tables or
GEMINI tables you have to pay an additional 30% on the standard
support price for each of the table handlers you would like to have
support for.
We at MySQL AB will help you create a proper bug report for the
table handler and submit it to the developers for the specific table
handler. We will also do our best to ensure that you will get a timely
answer or solution from the developers of the table handler.
Even if we are quite confident that we can solve most problems within a
timely manner, we can't guarantee a quick solution for any problems you
can get with the different table handlers. We will however do our best
to help you get the problem solved.
