Using the mongo command shell, create the "bios" collection from the Mongo documentation (http://docs.mongodb.org/manual/applications/create).

db.bios.insert(
   {
      _id: 1,
      name: { first: 'John', last: 'Backus' },
      birth: new Date('Dec 03, 1924'),
      death: new Date('Mar 17, 2007'),

                }
      ]
   }
)

In ADS, query the fields for the "bios" collection.

select * from V$AQUADATABASE.TABLE_COLUMNS where TABLE_DATABASE = 'test' and TABLE_NAME = 'bios'

The result set is:

Note that the "birth" and "death" fields have subfields "birth.tojson" and "death.tojson" with "function" data type.
