Property :: collectionLoid - Local collection identity
Collections in ODABA have got a unique identity like instances, which allows identifying a collection within a database. The function returns the local unique identity for the collection handled by the property handle.
In case the property handle is not handling a collection (e.g. for attributes), the function returns 0. When the property handle is invalid or another error has encountered, the function throws an exception.
Return value: Unique collection identifier ( int64 )
