insert

Connect to MongoDB® using the MongoDB C++ interface and export one document from MATLAB® and insert it into a collection. Specify the document to insert as a structure. In this example, the collection represents employee data.

Create a MongoDB connection to the database mongotest using the MongoDB C++ interface. Here, the database server dbtb01 hosts this database using port number 27017.

server = "dbtb01";
port = 27017;
dbname = "mongotest";
conn = mongoc(server,port,dbname)

conn = connection with properties:
           Database: "mongotest"
           UserName: ""
             Server: "dbtb01"
               Port: 27017
    CollectionNames: [13×1 string]

conn is the connection object that contains the MongoDB connection. The object properties contain information about the connection and the database.

Verify the MongoDB connection.

isopen(conn)

ans = logical
   1

The database connection is successful because the isopen function returns 1. Otherwise, the database connection is closed.

Create one document as the document structure with three fields. Set the employee_id field to 28, department_id field to 80, and salary field to 200,000.

document.employee_id = 28;
document.department_id = 80;
document.salary = 200000;

Specify the employees collection. Insert the document into the collection by using the MongoDB C++ interface connection. The insert function inserts one document into the collection.

collection = "employees";
n = insert(conn,collection,document)

n = int64
    1

Close the MongoDB connection.

close(conn)

Connect to MongoDB® using the MongoDB C++ interface and export multiple documents from MATLAB® and insert them into a collection. Specify documents to insert as a structure array. In this example, the collection represents employee data.

isopen(conn)

ans = logical
   1

The database connection is successful because the isopen function returns 1. Otherwise, the database connection is closed.

Create two documents as structures with these fields: employee_id, department_id, and salary. For the employee1 structure, set the employee_id field to 26, department_id field to 80, and salary field to 100,000. For the employee2 structure, set the same fields to the values 27, 90, and 150,000 respectively. Create the documents structure array from these documents.

employee1.employee_id = 26;
employee1.department_id = 80;
employee1.salary = 100000;

employee2.employee_id = 27;
employee2.department_id = 90;
employee2.salary = 150000;

documents = [employee1 employee2];

Specify the employees collection. Insert documents into the collection using the MongoDB connection. The insert function inserts two documents into the collection.

collection = "employees";
n = insert(conn,collection,documents)

n = int64
    2

Close the MongoDB connection.

close(conn)

Connect to MongoDB® using the MongoDB C++ interface and export documents from MATLAB® and insert them into a collection. Specify documents to insert as a table. In this example, the collection represents employee data.

isopen(conn)

ans = logical
   1

The database connection is successful because the isopen function returns 1. Otherwise, the database connection is closed.

Create two documents using these workspace variables:

Create the documents table from these workspace variables.

department_ids = [80;90];
employee_ids = [24;25];
salaries = [100000;150000];
documents = table(department_ids,employee_ids,salaries);

Specify the employees collection. Insert documents into the collection using the MongoDB connection. The insert function inserts two documents into the collection.

collection = "employees";
n = insert(conn,collection,documents)

n = int64
    2

Close the MongoDB connection.

close(conn)

Connect to MongoDB® using the MongoDB C++ interface and export documents from MATLAB® and insert them into a collection. Specify documents to insert as a cell array of structures. In this example, the collection represents employee data.
