I'm not sure that's even hypothetically possible, since white holes are defined so that they have properties that are the reverse of those of black holes: while mass falling into a black hole would never manager to escape its event horizon, mass falling into a white hole would never manage to reachits event horizon.
But the mathematics are complex, and I'm not sure anybody has ever even modelled such a collision...
When a white hole and a black hole collide, it is theorized that they would cancel each other out, resulting in the release of a burst of energy. This event is purely hypothetical as white holes have not been observed in nature.
When a black hole collides with a white hole, it is theorized that they would cancel each other out, resulting in the release of energy and potentially creating a new type of cosmic event.
If a black hole and a white hole were to collide, it is theorized that they would cancel each other out, resulting in the release of energy and potentially creating a new type of cosmic event. This collision could have significant implications for our understanding of the universe and the laws of physics.

Black Hole - comics - happened in 1995.
Black Hole Assault happened in 1992.
A white hole (assuming they actually exist) is simply a small black hole, so nothing very spectacular would happen. The black hole would just get very slightly more massive (well, considerably more massive on a "how many ounces is that" scale; not so much on a "how many solar masses is that" scale).
It disappears forever
Since whit holes only exist mathematically, a black hole could not pull in a white hole.
Well if it DOES happen and a black hole DOES destroy the Universe, then we won't be around to worry about it.
Objects which approach a black hole will get sucked into it.
Black Hole - video game - happened in 1981.
