    Just curious to know, how HCL claims that this one has been shipped, but the objects and classes mentioned here do not provide any methods for UNION. And how are we supposed to use this, if there is no documentation available for that?

    (Notes)QueryResultsProcessor supports multiple database input and computes and merges data by sort criteria. v12 provides UNION with ORDER BY (to provide SQL analogs) support. Joins can be performed across multiple returned entries.

    True joins will be supported later.
