Then use session, user will at most see the session key, no clue what values
may be stored.

I wouldn't really store the whole query in the session, but only the values to
be used in the query, that way you can do more with the values, like display
them or...

$_SESSION is the closes thing, you could store it on a file which you create
with the script, but that's kind of reinventing the wheel.
