I think the intro para quoted below is an oversimplification of the license policy--and one that (understandably) favors MySQL AB. My reading of that page is that it's the *distribution* of the MySQL source code (modified or not) or binaries that requires you to have a commercial license.
I take this: > 2. Free use for those who never copy, modify or distribute > > As long as you never distribute (internally or externally) > the MySQL Software in any way, you are free to use it for > powering your application, irrespective of whether your > application is under GPL or other OSI approved license or > not. > > More specifically: > > Modifying - You are allowed to modify MySQL Software source > code any way you like. If you distribute the modified > version, all changes, all interface code and all code that > connects directly or indirectly to the interface code fall > under GPL. > > Copying - You are allowed to copy MySQL binaries and source > code, but when you do so, the copies will fall under the GPL > license. to mean that apps that just run against MySQL do not have to be GPL'd. I'd bet you could even sell a commercial app that required MySQL to run, so long as you made your customers get & install their own copies of MySQL (that is, you did not distribute it yourself). But I haven't actually read the GPL, so I could be wrong...

In all other instances, you are better served by our commercial licence." If your application is 100% GPL (Gnu Public License) then you can use mySQL for free. If your application is NOT 100% GPL then you can use mySQL but you have to pay for it. > -----Original Message----- > From: Richard Ji [mailto:[EMAIL PROTECTED] > > What? Are you sure?
