Hi.
Try to investigate this:
https://backendless.com/documentation/data/js/data_search_and_query.htm
https://backendless.com/documentation/data/js/data_relations_retrieve.htm

On the second link you can find examples about retrieve object by it relations.

seems no a specific case for retrieving data from child to parent?

Hi Karlex,

If you know child’s objectId, you can run a query (a find operation) on the parent table with the following whereClause:

relationName.objectId = 'child-objectId'

This will retrieve the parent object of the specified child.
