For normal use MySQL costs nothing. When you sell MySQL directly or as a part of another product you have to pay for it. 「The MySQL server license」節参照 .
The client access part of MySQL is in the public domain. The command line client includes parts that is under the GNU Public License (readline).
These are our current license prices. All prices are in US Dollars. If you pay by credit card, the currency is FIM (Finish Marks) so the prices will differ slightly.

A full-price license includes really basic support. This means that we are trying to answer any relevant question. If the answer is in the documentation, we are going to direct you to the relevant documentation. If you do not have a license/support we will probably 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:

There are (at least) four different copyright's on the MySQL distribution.

states so. This is everything in the `client' directory and some parts of
mysys, mystring and dbug libraries.

Our philosophy behind this is:
This is a clarification of the information in the 'MySQL FREE PUBLIC LICENSE'. 「The MySQL server license」節参照 .
MySQL may be used freely, including by commercial entities for evaluation or unsupported internal use. However, distribution for commercial purposes of MySQL, or anything containing or derived from MySQL in whole or in part, requires a written commercial license from TcX AB, the sole entity authorised to grant such licenses.
You may not include MySQL "free" in a package containing anything for which a charge is being made except as noted below.
The intent of the exception provided in the second clause is to allow commercial organisations operating an FTP server or a bulletin board to distribute MySQL freely from it, provided that:
If you want to distribute software in a commercial context that incorporates MySQL and you do not want to meet these conditions, you should contact TcX AB to find out about commercial licensing. Commercial licenses involve a payment, and include support and other benefits. These are the only ways you legally can distribute MySQL or anything containing MySQL: either by distributing MySQL under the requirements of the FPL, or by getting a commercial license from TcX AB.
I want to sell a product that can be configured to use MySQL although my customer is responsible for obtaining/installing MySQL (or some other supported alternative). Does one of us owe you money if my customer chooses to use MySQL?
If your product REQUIRES MySQL to work, you would have to buy a license. If MySQL just added some new features it should fall inside normal use. For example, if using MySQL added logging to a database instead of a text file it would not require a license. This would, of course, mean that the user has to fetch and install MySQL by himself. If the program is (almost) useless without MySQL you would have to get a MySQL license to sell your product.
Do I have to get a license for my copy?
No, you are not selling MySQL itself. But in this case we would like you to purchase MySQL support. That is either your support of MySQL or our support of you (the later is more expensive since our time is limited).
Is your script designed for MySQL alone? Does it require MySQL to function at all? Or is it designed for `a database' and can run under MySQL, PostgreSQL, or something else?
If you've designed it strictly around MySQL then you've really made a commercial product that requires the engine, so you need to buy a license.
If, however, you can support any database with a base level of functionality (and you don't rely on anything that only MySQL supports) you probably DO NOT have to pay.
It also depends on what you're doing for the client. Are you tying into a database you expect to already exist by the time your software is purchased? Then you again probably don't have to pay. Or do you plan to distribute MySQL or give them detailed instructions on installing it with your software? Then you probably do.
One thing I'd like to suggest, folks. Look, development won't last forever if nobody pays. I agree that buying a copy for every software user is prohibitive compared to other products available but would it not be courtesy for commercial developers to register their OWN copy that they develop with?
We may choose to distribute older versions of MySQL with the GPL in the future. However these versions will be identified as GNU MySQL. Also all copyright notices in the relevant files will be changed to the GPL.
