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") newRestaurants := []interface{}{ Restaurant{Name: "Rule of Thirds", Cuisine: "Japanese"}, Restaurant{Name: "Madame Vo", Cuisine: "Vietnamese"}, } result, 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"}
