Stay connected with DB

[Manuel Jung]

Hi,

My application should stay connected with the Mysql Server or reconnected on
diconnect. It stays connected for a day or so, but always after a night
(where probably not querys where started) the connections are lost. 
Im trying to use Connection::ping for possibly reconnect, before i start
some MySQL Work, but it doesn't help. I also create a new query object
after pinging. (Query objects are just alive for a short time in my
application).

What is the preferred solution to keep connections alive or reconnect them
automaticly?

Kind Regards
