       }
    ]

How to update id 103 name field

Answer 1

You should use positional operators

db.test.update({"id":101, "review_ratings.id": 103},
               {$set: {"review_ratings.$.name":"mohit"}});

Answer 2

You can use aggregate function for searching and can use find and update method like:-

test.aggregate(
                [
                  { $match: {} },
                  {$project: {
                    review_ratings: {
                      $filter: {
                        input: '$review_ratings',
                        as: 'review_ratings',
                        cond: { $wq: [ '$$review_ratings.id', '103' ] }
                      }
                    }
                   }
                  }

                ],
                (err, res) => {

                });
