Python MongoDB insert_many Query (original) (raw)

Last Updated : 12 Jul, 2025

In MongoDB, **insert_many() method is used to insert multiple documents into a collection at once. When working with Python, this operation is performed using the PyMongo library.

Instead of inserting documents one by one with insert_one(), insert_many() allows developers to **pass a list of dictionaries, where each dictionary represents a document. This is a more efficient and cleaner approach when inserting bulk data into MongoDB.

Syntax

collection.insert_many(documents, ordered=True, bypass_document_validation=False, session=None, comment=None)

**Parameters:

• **documents (Required): A list of documents (dictionaries) to insert..
• **ordered (Optional, default=True): If True, stops inserting if one fails. If False, tries to insert all.
• **bypass_document_validation (Optional, default=False): If True, skips any validation rules.
• **session (Optional): Used for advanced tasks like transactions.
• **comment (Optional): Adds a note to the operation (from PyMongo v4.1).

Now, Let's explore some Examples:

Example 1:

In the below code, multiple student records are inserted with **predefined _id values into a collection.

Python `

from pymongo import MongoClient

client = MongoClient("mongodb://localhost:27017/") db = client["GFG"] collection = db["Student"]

List of student documents to insert

students = [ { "_id": 1, "name": "Vishwash", "roll_no": "1001", "branch": "CSE" }, { "_id": 2, "name": "Vishesh", "roll_no": "1002", "branch": "IT" }, { "_id": 3, "name": "Shivam", "roll_no": "1003", "branch": "ME" }, { "_id": 4, "name": "Yash", "roll_no": "1004", "branch": "ECE" } ]

Inserting the documents into the collection

collection.insert_many(students)

`

**Output:

Snapshot of Terminal showing Output of Insertion with _id provided

Example 2:

In this example **_id is not provided, it is allocated automatically by MongoDB.

Python `

from pymongo import MongoClient

Connect to MongoDB

myclient = MongoClient("mongodb://localhost:27017/")

Access the database and collection

db = myclient["GFG"] collection = db["Geeks"]

List of documents to be inserted

mylist = [ {"Manufacturer": "Honda", "Model": "City", "Color": "Black"}, {"Manufacturer": "Tata", "Model": "Altroz", "Color": "Golden"}, {"Manufacturer": "Honda", "Model": "Civic", "Color": "Red"}, {"Manufacturer": "Hyundai", "Model": "i20", "Color": "White"}, {"Manufacturer": "Maruti", "Model": "Swift", "Color": "Blue"}, ]

_id is not specified; MongoDB will assign unique ObjectId to each document

collection.insert_many(mylist)
