[Vampires] If you suck all the blood out of a vampire, would that kill them?

I know it definitely depends on the fiction, and age/power of the vampire. Their power comes from blood, their identity is in there blood. Some fiction says you are turned by drinking the blood of a vampire, and in turn forever bound to them. So if you drank one dry would that kill them, or merely incapacitate them?

In some cases, it might. Although currently more popular portrayal (like in Underworld or World of Darkness) is that vampires that are liberated from blood would instead hibernate and can lie like that for ages. In Underworld for example the vampire elders are preserved like that and infused with blood to wake them up. And in new world of darkness vampires who have no blood left in them just don't wake up and can spend years like this in torpor, slowly losing their power until they're disturbed, in which case they can wake up in a frenzy. 

Other kinds of vampires, like ones in Blade would probably just die.
