Insert Multiple Documents

You can insert multiple documents into a collection by using the InsertMany() method.

Example

Tip

Read the Usage Examples to learn how to run this example.

This example uses the following Restaurant struct as a model for documents in the restaurants collection:

type Restaurant struct {	Name         string	RestaurantId string        `bson:"restaurant_id,omitempty"`	Cuisine      string        `bson:"cuisine,omitempty"`	Address      interface{}   `bson:"address,omitempty"`	Borough      string        `bson:"borough,omitempty"`	Grades       []interface{} `bson:"grades,omitempty"`}

The omitempty struct tag omits the corresponding field from the inserted document when left empty.

The following example inserts two new documents to the restaurants collection:

Tip

Nonexistent Databases and Collections

If the necessary database and collection don't exist when you perform a write operation, the server implicitly creates them.

coll := client.Database("sample_restaurants").Collection("restaurants")
// Creates two sample documents describing restaurantsnewRestaurants := []interface{}{	Restaurant{Name: "Rule of Thirds", Cuisine: "Japanese"},	Restaurant{Name: "Madame Vo", Cuisine: "Vietnamese"},}
// Inserts sample documents into the collectionresult, err := coll.InsertMany(context.TODO(), newRestaurants)if err != nil {	panic(err)}

Expected Result

After you run the full example, you can find the following inserted documents in the restaurants collection:

  { "_id": ObjectID("..."), "name": "Rule of Thirds", "cuisine": "Japanese"},  { "_id": ObjectID("..."), "name": "Madame Vo", "cuisine": "Vietnamese"}
