How to Find Documents in MongoDb where some fields are not null -


How to obtain a list of documents in Mongode where some fields are not zero.

: If a student is not enrolled in name or age or course which should not be in the results collection.

This should work: 

  db.student.find ( {'Name': {$ Ne: null}, 'course': {$ ne: null}, 'age': {$ ne: null}})
