Hi,
I think that @isoul means that there isn't function which checks if tcp
connection with database isn't broken.
Use case: long running server which doesn't make many queries to server.
Before next query it checks if the tcp connection still exists:
if (!sql.isConnected())
sql.reconect();
// ... do query
It isn't perfect but provides simple pattern for reconnecting when tcp
connection goes out.
Also maybe there should be possibility to create connection_pool with
parameter auto_reconnect = true; which ensures that sessions taken from
connection_pool are connected or it will throw execption.
