Not really. The GPL specifies that If I use the code of MySql and then make
modifications to that code to make another database server then I would be
obligated to GPL my derived database server (only if I choose to distribute
it to the public). The GPL does not touch me if I make a separate product
that uses the mysql engine. As long as I don't steal their code I am immune
from the GPL. Only when you actually attempt to benefit from their hard
work will you be subject to their terms.

For example I can make a mysql schema generation tool or a mysql data
migration tool using Delphi or VB and be free to charge whatever I want for
it because I did not steal any code from the MySql database server. But If
I want to make "yourSQL" and do so by modifying the "mysql" code then I
have to make "yourSQL" open source. OTOH if I only want to make "yourSQL"
be available in my company and nowhere else then I'm OK.
