stddev() is not a part of the standard sqlite package. (source: https://www.sqlite.org/contrib?orderby=date )
I could probably add it, however, so will leave this open as a feature request
from textql.
Ok. I got my hopes up based on lines 805-808 from ast.go ...
805 "std": true,
806 "stddev_pop": true,
807 "stddev_samp": true,
808 "stddev": true,
from textql.
No, that means that if https://github.com/mattn/go-sqlite3 supported it out of the box it would work, but it doesn't
from textql.
Do you recommend looking into "extension-functions.c" (50.96 KB) contributed by Liam Healy from the webpage that you referenced?

Love this tool, btw!

Well, if you wanted to add it, we would need a version of https://github.com/mattn/go-sqlite3 that loads that file and builds it into it's output, then we can build textql against that.
Alternatively, if you are lazy; here is the SQLLite code for stddev
SELECT AVG((t.row - sub.a) * (t.row - sub.a)) as var from t,
(SELECT AVG(row) AS a FROM t) AS sub;

Thanks, I hope it does help people :)
