It depends on the server-side language you are using? Which language are
you intending on programming in?

Hi Miguel --
when you query on a particular field in that document, is the *_id* field
being returned?  The _id field should contain the ObjectID of the document.

If you don't see the _id field as part of the resulting document, could you
specify the query that you are running?  

Regards,

Kay

I am using pymongo .
The query I am running is collection.find().

This works fine for showing with a for loop every field I want to see for
the whole database.

Now for every document I want to see the ObjectId so I can run another
query to view only the fields of that document.

Someone can help ?

Hi Miguël --

Sorry for the delay but was this what you were trying to do -- access the
_id field which contains the ObjectID?

>>> myRecords = myCollection.find( { }, { '_id': 1 } )
>>> for record in myRecords:

record['_id']

Regards,

Kay
