Hi Dinesh
I have some bad news for you I'm afraid. Discoverer workbooks are not stored as SQL definitions, they are stored as BLOBs within the database. It is therefore not possibly to write any sort of query to interrogate the inner workings of a workbook. The only way to do this is to open each workbook in turn and analyze it.
Sorry to be the bringer of bad news
Best wishes
Michael
