What's the output json look like? Also, I have support for unsigned integers if you want to add those to your frontend (I think it's relatively standard with UNSIGNED)

You can also extend your integer support some if you want, I can support everything from 8bit to 128bit integers (signed and unsigned) and if we really wanted I could also support arbitrary bit sizes less than 128 (e.g. INTEGER(7) = i7)

Unfortunately SQL has no support for unsigned integers, so I don't know how to generate properly such code. I think you should try to build the compiler, it's really one command-line you need to run if you have installed java and maven. Then you can generate lots of json easily - one more command-line.
