Standard Deviation for SQLite

Question

I've searched the SQLite docs and couldn't find anything, but I've also searched on Google and a few results appeared.

Does SQLite have any built-in Standard Deviation function?

Answer 1

No, I searched this same issue, and ended having to do the calculations with my application (PHP)

Answer 2

The aggregate functions supported by SQLite are here:

http://www.sqlite.org/lang_aggfunc.html

STDEV is not in the list.

However, the module extension-functions.c in this page contains a STDEV function.
