I'll give that anoher testing. I thought I was trying this with '' and
None, and got for both an 'Can't render that to int' error, but maybe I
forgott the optional, I'll figure out.

Maybe, ZSQL is not the best joice for me, when I've got to say the
method what not to do, I'm afraid to forget something ... also I can't
add another parameter later without changing all calls to the method.

Otherwise, the behavior of ZSQL can be strong, so, I shout not use ZSQL
or change the way of using it.
