Using findOneAndUpdate () to update in MongoDB?

The findOneAndUpdate() is used to update a single document based on the filter and sort criteria i.e. −

db.collection.findOneAndUpdate(filter, update, options)

Let us create a collection with documents −

> db.demo328.insertOne({Name:"Chris",Marks:67}); {    "acknowledged" : true,    "insertedId" : ObjectId("5e516b19f8647eb59e56207a") } > db.demo328.insertOne({Name:"David",Marks:78}); {    "acknowledged" : true,    "insertedId" : ObjectId("5e516b24f8647eb59e56207b") } > db.demo328.insertOne({Name:"Bob",Marks:97}); {    "acknowledged" : true,    "insertedId" : ObjectId("5e516b2bf8647eb59e56207c") }

Display all documents from a collection with the help of find() method −

> db.demo328.find();

This will produce the following output −

{ "_id" : ObjectId("5e516b19f8647eb59e56207a"), "Name" : "Chris", "Marks" : 67 } { "_id" : ObjectId("5e516b24f8647eb59e56207b"), "Name" : "David", "Marks" : 78 } { "_id" : ObjectId("5e516b2bf8647eb59e56207c"), "Name" : "Bob", "Marks" : 97 }

Following is the query to update with findOneAndUpdate(). Here, we are incrementing a specific document’s field Marks −

> db.demo328.findOneAndUpdate({Name:"David"},{ $inc: { "Marks" : 10} }); {    "_id" : ObjectId("5e516b24f8647eb59e56207b"),    "Name" : "David",    "Marks" : 78 }

Display all documents from a collection with the help of find() method −

> db.demo328.find();

This will produce the following output −

{ "_id" : ObjectId("5e516b19f8647eb59e56207a"), "Name" : "Chris", "Marks" : 67 } { "_id" : ObjectId("5e516b24f8647eb59e56207b"), "Name" : "David", "Marks" : 88 } { "_id" : ObjectId("5e516b2bf8647eb59e56207c"), "Name" : "Bob", "Marks" : 97 }
