SQL Injection is very hard to pull off with the Oxwall Software - you'd need many tools and services running from multiple nodes to create a vulnerability in a website running Oxwall.
If your site with Oxwall is facing SQL Injection problems though (and you tested it), you should be able to reverse engineer any form of hacking to stop it from occurring. I can't offer any solution to your question at this moment however, because I've rarely seen any problems related to SQL Injection and Oxwall.
