Um, I think you'd need to use Python SQL libraries or code a plugin for that. Should be possible though. Take a look at the python tutorials on this list: [url:n4ask2rt]http://www.scirra.com/forum/viewtopic.php?f=8&t=8169[/url:n4ask2rt]
>> But can I use podsixnet + this pymsmql at the same time? Yes, you can definitely combine them at the same time.
>> although I heard podsixnet can be pretty laggy sometimes. Lag isn't an issue when accessing SQL databases (at least in choice of library to use). Podsixnet will perform just as good as Raknet or any other fast UDP library when it comes to things like this.
On a separate note, to reduce the appearance of lag w/ Podsixnet you can use client-side interpolation and also use ping times to adjust your positions. Client-side interpolation is really easy to implement in construct using lerp() and timedelta.
