Can anyone give me the query for this ? No. Not until you give us the rule that governs whether FILES is joined to PGM_FILES_BATCH or PGM_FILES_ONLINE.
However, I can say this: your best bet is to write two queries, FILES JOIN PGM_FILES_BATCH and FILES JOIN PGM_FILES_ONLINE and use UNION ALL to munge the results into a single output.
