How to insertmany records in mongodb?

To insert multiple records (documents) in MongoDB, you can use the insertMany() method. Here is an example of how to use it in the MongoDB Shell:

> use mydatabase
> db.mycollection.insertMany([
   { item: "journal", qty: 25, size: { h: 14, w: 21, uom: "cm" }, status: "A" },
   { item: "notebook", qty: 50, size: { h: 8.5, w: 11, uom: "in" }, status: "A" },
   { item: "paper", qty: 100, size: { h: 8.5, w: 11, uom: "in" }, status: "D" },
   { item: "planner", qty: 75, size: { h: 22.85, w: 30, uom: "cm" }, status: "D" },
   { item: "postcard", qty: 45, size: { h: 10, w: 15.25, uom: "cm" }, status: "A" }
])

This will insert the specified documents into the mycollection collection in the mydatabase database.

You can also use the insertMany() method in various MongoDB drivers, such as the MongoDB Node.js driver. Here is an example of how to use it in Node.js:

const MongoClient = require('mongodb').MongoClient;

const uri = "mongodb+srv://<username>:<password>@cluster0.mongodb.net/test?retryWrites=true&w=majority";
const client = new MongoClient(uri, { useNewUrlParser: true });
client.connect(err => {
  const collection = client.db("test").collection("devices");
  collection.insertMany([
    { name: 'keyboard' }, { name: 'mouse' }
  ], function(err, result) {
    console.log("Inserted 3 documents into the collection");
    client.close();
  });
});

This will insert the documents { name: 'keyboard' } and { name: 'mouse' } into the devices collection in the test database.

I hope this helps! Let me know if you have any questions.

To insert multiple records in MongoDB, you can use the insertMany() method. Here's an example:

1. Establish a connection to the MongoDB server using a MongoDB client. For example, in Node.js using the official MongoDB client:

const MongoClient = require('mongodb').MongoClient;
const url = 'mongodb://localhost:27017';

MongoClient.connect(url, (err, client) => {
  if (err) throw err;
  console.log('Connected to MongoDB server');
  
  const db = client.db('<database_name>');
  
  // Insert many records
  const records = [
    { name: 'John Doe', age: 30 },
    { name: 'Jane Smith', age: 25 },
    { name: 'Bob Johnson', age: 35 }
  ];

  db.collection('<collection_name>').insertMany(records, (err, result) => {
    if (err) throw err;
    console.log('Records inserted:', result.insertedCount);
  
    client.close();
  });
});

Replace <database_name> with the name of the database where you want to insert records and <collection_name> with the name of the collection within that database.

1. Define an array of objects representing the records you want to insert. Each object should contain the fields and values for each record.
2. Use the insertMany() method on the collection to insert the records. Pass in the array of records as the first parameter. The method takes a callback function, which will be executed once the records are inserted. This callback function receives an error object and a result object.
3. In the callback function, you can check if there was an error during insertion. If successful, the insertedCount property of the result object will indicate the number of records inserted.
4. Finally, close the connection to the MongoDB server using client.close().

Note that insertMany() will insert all the records provided at once, which can be more efficient than inserting them one by one using insertOne().
