If the subset of IDs is large, and disjoint (so that you cannot use ranges), the query might look ugly, but generating it should not be much of a problem if you are using some automated method to create the query. If you mean whether it will be efficient enough, the only way is to try it out, and measure performance. Offhand, I do not think that it should increase the query response time by a lot.
