The standard SQLite function random() is actually seeded by
the current time and date every time you open a database.
FWIW, the random() function in SQLite uses a cryptographic
PRNG and (at least on Unix) is seeded using /dev/urandom
if that device is available. So it should give you very
good randomness.

You are of course right, I just looked at the Windows version which is
seeded on date/time.
Sorry, but I can't miss to write:
Steve, If you're going to offer advice, at least do some basic research
to make sure it's accurate.
