We have used the existing database and collection Company, artists respectively. After that, we have used MongoClient class to make the connection with the server. In this above code first, we have imported the python pymongo library to use the MongoDB functionality in python. # accessing the collection of the database # creating a MongoClient object and connect with the host Step 1 Preparing the Sample Database To explain how to create queries in MongoDB including how to filter documents with multiple fields, nested documents, and arrays this guide uses an example database containing a collection of documents that describe the five highest mountains in the world. In the example, we will use an existing database and collection and find documents by their id accordingly: import pymongo Now, we will cover this with the help of an example and find documents by id using python. In this topic, you will learn to find a particular document by their id using python.

Read: Export MongoDB to CSV MongoDB find by id not working We have successfully retrieved the documents by their id using MongoDB compass. MongoDB compass find the document by their id Alternatively you can also use the powerful MongoDB aggregation pipeline for queries. Here, we have defined the specific id in the find() method to retrieve the specific document. The following example queries for documents where the dimcm array contains elements that in some combination satisfy the query conditions e.g. MongoDB supports find() command for queries. The schema types for these properties are automatically. db.animal.insertMany([Īfter inserting the documents into the collection, apply the below query to find where the id equals. For example, in the schema definition above, we defined three properties: name, age, and breed. The following documents were inserted into the animal collection. Now we will understand this with the help of an example. In this topic, you will learn to find the documents of a particular id equals. Master MongoDB Development for Web & Mobile Apps. Returns: The find() method “returns documents” method is returning a cursor to the documents.Īlso, check: Import JSON and insert JSON into MongoDB MongoDB find where id equals Optional, Defines the fields to return in the documents that match the query filter. To find all documents in a collection, drop this parameter or pass an Optional, specifies selection filter using the This query selects documents in a collection and returns a cursor to the selected documents. ![]() Syntax: db.collection.find(query, projection) In MongoDB, you can use the find() method to retrieve the documents from the collection.
