Example MongoDB Insert Many Documents

Let's look at some examples of how to use the insertMany method in the programGuru collection in MongoDB:

1. Insert Multiple Documents

db.programGuru.insertMany([
    { name: "John Doe", age: 30, email: "john.doe@example.com" },
    { name: "Jane Smith", age: 25, email: "jane.smith@example.com" },
    { name: "Jim Brown", age: 35, email: "jim.brown@example.com" }
])

This command inserts multiple documents with the fields name, age, and email into the programGuru collection.

Full Example

Let's go through a complete example that includes switching to a database, creating a collection, and inserting multiple documents.

Step 1: Switch to a Database

This step involves switching to a database named myDatabase.

use myDatabase

In this example, we switch to the myDatabase database.

Step 2: Create a Collection

This step involves creating a new collection named programGuru in the myDatabase database.

db.createCollection("programGuru")

Here, we create a collection named programGuru.

Step 3: Insert Multiple Documents into the Collection

This step involves using the insertMany method to insert documents into the programGuru collection.

db.programGuru.insertMany([
    { name: "John Doe", age: 30, email: "john.doe@example.com" },
    { name: "Jane Smith", age: 25, email: "jane.smith@example.com" },
    { name: "Jim Brown", age: 35, email: "jim.brown@example.com" }
])

We insert multiple documents with the fields name, age, and email into the programGuru collection.

Conclusion

The MongoDB insertMany operation is crucial for bulk inserting records into collections. Understanding how to use this method allows you to efficiently add and manage large amounts of data within MongoDB collections.
