Yes, you can achieve this with findAndModify(). Let us first create a collection with documents −
> db.returnResultOfIncementDemo.insertOne({"PlayerScore":98}); { "acknowledged" : true, "insertedId" : ObjectId("5cd3c292edc6604c74817cda") }
Following is the query to display all documents from a collection with the help of find() method −
> db.returnResultOfIncementDemo.find();
This will produce the following output −
{ "_id" : ObjectId("5cd3c292edc6604c74817cda"), "PlayerScore" : 98 }
Following is the query to return result of increment. Here, we have incremented PlayerScore by 2 −
> db.returnResultOfIncementDemo.findAndModify({ ... query:{}, ... update: { $inc: {PlayerScore: 2 }}, ... new: true ... });
This will produce the following output −
{ "_id" : ObjectId("5cd3c292edc6604c74817cda"), "PlayerScore" : 100 }
