[Fantasy in general] Can necromancer raise both ghost and corpse, effectively getting two minions from one body?

How necromancy works can obviously differ from one universe to another. I am especially curious about Warhammer, Warcraft or DnD altough any imput is welcome.

It is possible for a skilled necromancer to reanimate dead body in a form of a zombie, a skeleton or something similar consisting of a corporeal body. And then summon a ghost/wraith of the former occupant of said body to serve his will seperatelly of said body?

Alternatively: what form of necromancy leaves a body and soul intact yet still undead and obedient?

This very much depends on the world, because magic is different. Sometimes the answer is yes, sometimes no.

Some kinds of zombie-raising is simply hijacking the corpse and using it as a meat-puppet. This kind of raising is relatively rare because it requires a lot more energy on the part of the caster (since they have to actively command the corpse). However, this leaves the soul, or spirit, intact, and perhaps even in the afterlife. It is possible, therefore, for that caster or another caster to bind the soul to themselves and force it back into the mortal realm.

Sometimes, though, it's quite unfeasible to manually puppet every zombie one raises. Ghosts, too, being largely immaterial, are mostly useless for any practical function save being spooky or talking. As a result, many casters decide to instead take both body and soul in the zombie-raising process. Re-bind the soul to the corpse, and bind the soul into doing your bidding. Of course, you're unlikely to ever get a creature as lucid as the original person, but you can get some simulacrum of aliveness this way, as well as a much less intensive way of getting a minion. With a bound soul "piloting" your new abomination, you only have to give it orders and it will figure out the minutae of carrying those orders out on its own. Through this route, of course, no ghost can be summoned until the current soul is freed from its meaty prison.

Often, you'll see people opt to raise zombies in the latter method. After all, if they want a zombie thrall to do their bidding, they likely will not be interested in an immaterial ghost that is not capable of performing many useful tasks. However, some may choose to raise only the ghost - mostly out of a desire to talk to it for one reason or another. There are very few conceivable circumstances where a necromancer would want to or be forced to do both at the same time.
