AND '$today' ": The database just converted $today into a TRUE/FALSE question. And since the only way to answer a T/F question is with 1/0 in a computer, it decides that $today is not 0, because it's got numbers ands stuff in it. So it's ALWAYS true. So your query really turned into: where today = '0000-00-00' and TRUE The "and TRUE" bit doesn't really do much, you see... $x AND TRUE === $x Actually, NULL might turn into false, if you have NULL dates. And for technical reasons, midnight of January 1, 1970, might turn into 0... But ignore that for now, as you're typing something silly anyway, and you want " where date = '0000-00-00' and date = '$today' " Next, think about this: date = '0000-00-00' AND date = '2007-05-08' Is it possible for any date to be = to both of those values at once? No. A date cannot be both 0000-00-00 and also be today as well. Unless maybe you've invented a time machine... :-) > I just get items with '0000-00-00' returned or if I reverse it ie... > > WHERE date = '$today'AND '0000-00-00'"); > > I just get $today items returned. > > I also tried using OR instead of AND ie... > > WHERE date = '0000-00-00' OR '$today'"); > > But that seems to be returning all items in the db. This, of course, turns into: date = '0000-00-00' OR TRUE and that is always TRUE: $x OR TRUE === TRUE Hope that helps. Technically, this was all SQL, but it applies equally well in PHP with && and any programming language. -- Some people have a "gift" link here. Know what I want?
