License question

[Mauricio Pellegrini]

Hi,

Sorry to ask this in here. If it's not the right place please ignore the
post.

I want to know if someone could claim a license upon an application wich
was developed using Php and a non-commercially-licensed copy of MySql.

I mean, the application is designed to work only with MySql as database
engine and the MySql package delivered with the application, is licensed
under GPL.

Could the developer claim License rights upon the use of such a
combination ?

Thanks
Mauricio
