Querying parent child sets

Question

Hi
I have a cube with a dimension that has a value based hierarchy (id, description,parent)
Is it possible to query the cube to get parent child sets ?
I want the result set to look like
Member Value Parent
Parent_1 Measure_Value NULL
Child_1.1 Measure_Value Parent_1
Child_1.2 Measure_Value Parent_1
Parent_2 Measure_Value NULL
Child_2.1 Measure_Value Parent_2
Child_2.2 Measure_Value Parent_2
Also I am using a java front end,so I would like to do some pagination
So I would like say 1st 50 sets , 2nd 50 sets and so on

Cube Materialized Views are only created if you enable them and they are also only compatible with level based hierarchies. So MVs are not appropriate in your case.
If you are generating your own SQL then you could consider a hybrid approach by combining OLAP DML and SQL to get the explicit list of members. First execute the following OLAP DML.
LIMIT my_dim TO 'Parent_1' 'Parent_2'
LIMIT my_dim ADD DESCENDANTS USING my_dim_parentrel
SORT my_dim HIERARCHY my_dim_parentrelNow get the dimension members via either OLAP DML (e.g. REPORT command) or running SQL after the limit above. This gives you the explicit list of members that you can feed into a subsequent query.
SELECT dim_key, ...
FROM my_dim_view, cube_view
WHERE
  <join condition>
  AND dim_key IN (...list from report command...}
  Make sure you set status back via ALLSTAT after getting the list or it will change results later.
