Which problem, and why "of course"? Sorry, I can't follow you
here :)

I'm not exactly sure how you connect to that SQL server ... you
shouldn't wait for the response of the MySQL server in a blocking
way, but either using dataReceived() method of the protocol
instance or, if that isn't possible, by using a Deferred instance
that fires when the answer is available. This is also possible with
your client connections.
