Re: probleme with exeptions

It looks like your exception is coming from the underlining c++ string stuff and not from mysql++.

You can try adding in a catch all for std::exception or just a "...", e.g.

catch ( const std::exception& e) {
// do something
}
or
catch ( ... ) {
// do something
}

You also might want to do a stack trace to see what's generating that exception.

I hope that helps in some way...
