I've just added a somewhat complete (but usable) SQL module for newLISP to the modules page on Artful Code (http://static.artfulcode.net/newlisp/). It is intended as a basis for other applications to programmatically write SQL. While it is not yet feature-complete, it is quite functional and is also an excellent example of generic functions and my new functional module. Take a look and let me know if you find any bugs!
