Unfortunately that's not what MySQL AB licensing person told me. The
license is more strict than that. If your company distributes an
application that uses MySQL database inside the company (even inside the
same building), and you don't give the other dept the source code (so it
falls outside the gpl license) then the dept receiving the application
needs to have a MySQL license. In other words, the complete application
source code must follow the application.
If you have a commercial application running in Windows, and expect to sell
a lot of applications, it will cost you $595 per database server *per year*.
See https://shop.mysql.com/network.html?rz=s2. I didn't realize myself it
is now a per server/per year pricing either and it came as quite a shock to
me system. This can add up if you have a thousand applications in
circulation because each customer needs to pay $595/year. If this is too
pricey for you, there are open source databases out there that are free to
use and free to distribute. FireBird and ProgreSQL come to mind. And there
are other commercial databases where you pay up front and have no
distribution fees whatsoever.
