MongoDB Insert Methods:MongoDB provides the following methods for inserting documents into a collection:db.collection.insertOne() Inserts a single document i. ![]() We have added few documents into collection named Book. In our case connected Databse name is “TechDB” Let check the documents created on Collection “Book” using below command.ĭb – refer to connected database. Its syntax is the same as that of single insert in insert().ī) An array of _id for each successfully inserted documentsģ - InsertMany() - Inserts multiple documents into a collection.ĭ) An array of _id for each successfully inserted documents It allows you to insert exactly 1 document in the collection. It show only a message for successfully inserted.Ģ - InsertOne()- Inserts a document into a collection. In this method no document returned by application.

If the collection does not exist, the insert() method creates the collection. The examples on this page reference the Atlas sample dataset. To insert multiple documents, use db.collection.insertMany (). In this example we are going to create a collection named “Book” in TechDB Databse. The MongoDB shell provides the following methods to insert documents into a collection: To insert a single document, use db.collection.insertOne (). ![]() There are three methods available to insert documents into collection.ġ - Insert() - Inserts a document or documents into a collectionĮxample: Let’s take an example to show how to insert a document or documents into a collection. 1 Document in MongoDB Collection = 1 Row in RDBMS Table ![]()
