Insert Multiple Documents

You can insert multiple documents into a collection in a single operation by calling the insertMany() method on a MongoCollection object. To insert them, add your Document objects to a List and pass that List as an argument to insertMany(). If you call the insertMany() method on a collection that does not exist yet, the server creates it for you.

Upon successful insertion, insertMany() returns an instance of InsertManyResult. You can retrieve information such as the _id fields of the documents you inserted by calling the getInsertedIds() method on the InsertManyResult instance.

If your insert operation fails, the driver raises an exception. For more information on the types of exceptions raised under specific conditions, see the API documentation for insertMany(), linked at the bottom of this page.

Example

The following snippet inserts multiple documents into the movies collection.

Note

This example connects to an instance of MongoDB using a connection URI. To learn more about connecting to your MongoDB instance, see the connection guide.

// Inserts sample documents describing movies by using the Java driver
package usage.examples;
import java.util.Arrays;
import java.util.List;
import org.bson.Document;
import com.mongodb.MongoException;
import com.mongodb.client.MongoClient;
import com.mongodb.client.MongoClients;
import com.mongodb.client.MongoCollection;
import com.mongodb.client.MongoDatabase;
import com.mongodb.client.result.InsertManyResult;
public class InsertMany {
    public static void main(String[] args) {
        // Replace the uri string with your MongoDB deployment's connection string
        String uri = "<connection string uri>";
        try (MongoClient mongoClient = MongoClients.create(uri)) {
            MongoDatabase database = mongoClient.getDatabase("sample_mflix");
            MongoCollection<Document> collection = database.getCollection("movies");
            // Creates two sample documents containing a "title" field
            List<Document> movieList = Arrays.asList(
                    new Document().append("title", "Short Circuit 3"),
                    new Document().append("title", "The Lego Frozen Movie"));
            try {
                // Inserts sample documents describing movies into the collection
                InsertManyResult result = collection.insertMany(movieList);
                // Prints the IDs of the inserted documents
                System.out.println("Inserted document ids: " + result.getInsertedIds());
            
            // Prints a message if any exceptions occur during the operation
            } catch (MongoException me) {
                System.err.println("Unable to insert due to an error: " + me);
            }
        }
    }
}

When you run the example, you should see output that resembles the following with the inserted documents' ObjectId values in each of the value fields:

Inserted document ids: {0=BsonObjectId{value=...}, 1=BsonObjectId{value=...}}
