I should just get used to glancing that manual again before opening my mouth. As usual with pl, It's In There.
BTW, I think there are two kinds of SQL bindings for Lua: single-target, and ones with SQL mini parsers--because you can't do portable parameterized queries, and if you don't need parameterized queries in a program, why are you using SQL?
What's pl's compatibility profile these days? 5.1+5.2? I've been avoiding doing it seriously, but the still-on-rushing JSON juggernaut suggests a need for jsom.
