The easiest solution here is to link the table from another namespace. Only takes a second and you don't need to screw around getting the storage right (note: do NOT start editing storage defs if you can avoid it - that is not an easily maintained solution). This solution does not work if you have to JOIN the two tables together (we call this a heterogeneous JOIN), however. The next best solution is to write your own class query as @Stephen Canzano & @Michael Smart have recommended. It's a little work up front but you can make some easy changes, such as creating a temp table and populating it with data from the other namespace or using a process private global.
