Whats the difference between Hierarchy and HierarchyBelongsTo functions?

[mwallman]

Hi,

Can anybody please tell me what the difference is between Hierarchy and HierarchyBelongsTo functions please?

When would you use one over the other?

Have a look at

Unbalanced, n-level hierarchies

and to the referenced tech doc:

Hierarchies

Both variants of HierarchyXXXX LOAD prefix are explained in these documents, including samples.
