The Collection.add()
function is for storing
documents in a collection, similar to the
INSERT statement for an SQL
database. It takes a single document or a list of documents as
its argument, and is executed by the
execute()
function.
The collection needs to be created with the
Schema.createCollection()
function before
documents can be inserted. To insert documents into an existing
collection use the Schema.getCollection()
function to retrieve the Collection object.
The following example shows how to use the
Collection.add()
function. The example
assumes that the test schema exists and that the collection
my_collection
does not exist.
MySQL Shell JavaScript Code
Press CTRL+C to copy// Create a new collection var myColl = db.createCollection('my_collection'); // Insert a document myColl.add({ name: 'Laurie', age: 19 }).execute(); // Insert several documents at once myColl.add([ { name: 'Nadya', age: 54 }, { name: 'Lukas', age: 32 } ]).execute();
MySQL Shell Python Code
Press CTRL+C to copy# Create a new collection myColl = db.create_collection('my_collection') # Insert a document myColl.add({ 'name': 'Laurie', 'age': 19 }).execute() # Insert several documents at once myColl.add([ { 'name': 'Nadya', 'age': 54 }, { 'name': 'Lukas', 'age': 32 } ]).execute()
Node.js JavaScript Code
Press CTRL+C to copy// Create a new collection db.createCollection('myCollection').then(function (myColl) { return Promise.all([ // Insert a document myColl .add({ name: 'Laurie', age: 19 }) .execute(), // Insert several documents at once myColl .add([ { name: 'Nadya', age: 54 }, { name: 'Lukas', age: 32 } ]) .execute() ]) });
C# Code
Press CTRL+C to copy// Assumptions: test schema assigned to db, my_collection collection not exists // Create a new collection var myColl = db.CreateCollection("my_collection"); // Insert a document myColl.Add(new { name = "Laurie", age = 19 }).Execute(); // Insert several documents at once myColl.Add(new[] { new { name = "Nadya", age = 54 }, new { name = "Lukas", age = 32 } }).Execute();
Python Code
Press CTRL+C to copy# Create a new collection my_coll = my_schema.create_collection('my_collection') # Insert a document my_coll.add({ 'name': 'Laurie', 'age': 19 }).execute() # Insert several documents at once my_coll.add([ { 'name': 'Nadya', 'age': 54 }, { 'name': 'Lukas', 'age': 32 } ]).execute()
Java Code
Press CTRL+C to copy// Create a new collection Collection coll = db.createCollection("payments"); // Insert a document coll.add("{ \"name\":\"Laurie\", \"age\":19 }").execute(); // Insert several documents at once coll.add("{ \"name\":\"Nadya\", \"age\":54 }", "{ \"name\":\"Lukas\", \"age\":32 }").execute();
C++ Code
Press CTRL+C to copy// Create a new collection Collection coll = db.createCollection("payments"); // Insert a document coll.add(R"({ "name":"Laurie", "age":19 })").execute(); // Insert several documents at once std::list<DbDoc> docs = { DbDoc(R"({ "name":"Nadya", "age":54 })"), DbDoc(R"({ "name":"Lukas", "age":32 })") }; coll.add(docs).execute();
