Schenectady and Glenville have had 18 wheelers and RVs in there parking lots overnight. Not sure about cars.
I don't work there myself but some Walmart's you can stay there all night in the parking lot if you're a camper it depends on the store and it also depends on if you're far enough away from this if they have a back parking lot where you're not anywhere near the front of the store I think you'll be okay
They are not 24 hr, so they may not allow it. Walmart as a chain used to be really friendly to parking overnight, but I understand they've started clamping down on that at some locations.
I'm going to guess Yes you can park overnight because I always see tractor trailers parked over there.
I think they're open all night so I guess you could park your car there overnight
