The title says it all.
Dracula (and in some/many lores, normal vampires) are capable of bat form.
What happens if a regular vampire or Dracula is exposed to sunlight in their bat form? The same burning decay, or are they capable of surviving (or surviving longer) when in bat form?
 Obviously, restrict the question to lore which actually features vampires in bat form, and sunlight as an ill effect.
 I'm not looking for a single answer, but a list of answers from different universes.
