Then you'll get a tuple that looks like:

     "UPDATE %s SET key=%s, value=%f ", key, value, "WHERE index < %d AND ", 
index, "timestamp > %D", lastTime

which won't work for printf or writefln.

Since the other method works, I am striving to keep things as simple as 
possible. There needs to be very good reasons for gratuitous multiple ways of 
doing something, and I don't see one here. Of course, then there's "what about 
qi strings", aaggghhhh.
