CData Connect



Execute MySQL queries against Azure Table data from Node.js.

You can use CData Connect Cloud to query Azure Table data through a MySQL interface. Follow the procedure below to create a virtual database for Azure Table in Connect Cloud and start querying using Node.js.

CData Connect Cloud provides a pure MySQL, cloud-to-cloud interface for Azure Table, allowing you to easily query live Azure Table data in Node.js — without replicating the data to a natively supported database. As you query data in Node.js, CData Connect Cloud pushes all supported SQL operations (filters, JOINs, etc) directly to Azure Table, leveraging server-side processing to quickly return Azure Table data.

Create a Virtual MySQL Database for Azure Table Data

CData Connect Cloud uses a straightforward, point-and-click interface to connect to data sources and generate APIs.

  1. Login to Connect Cloud and click Databases.
  2. Select "Azure Table" from Available Data Sources.
  3. Enter the necessary authentication properties to connect to Azure Table.

    Specify your AccessKey and your Account to connect. Set the Account property to the Storage Account Name and set AccessKey to one of the Access Keys. Either the Primary or Secondary Access Keys can be used. To obtain these values, navigate to the Storage Accounts blade in the Azure portal. You can obtain the access key by selecting your account and clicking Access Keys in the Settings section.

  4. Click Test Database.
  5. Click Privileges -> Add and add the new user (or an existing user) with the appropriate permissions.

With the virtual database created, you are ready to connect to Azure Table data from any MySQL client.

Query Azure Table from Node.js

The following example shows how to define a connection and execute queries to Azure Table with the MySQL module. You will need the following information:

  • Host name, or address, and port: The address of your instance of the Connect Cloud (myinstance.cdatacloud.net) and the port (3306)
  • Username and password: The username and password of a user you authorized on Connect Cloud
  • Database name: The database you configured for Azure Table (azuredb)

Connect to Azure Table data and start executing queries with the code below:

var mysql      = require('mysql');
var fs         = require('fs');
var connection = mysql.createConnection({
  host     : 'myinstance.cdatacloud.net',
  database : 'azuredb',
  port	   : '3306',
  user     : 'admin',
  password : 'password',
  ssl      : {
    ca : fs.readFileSync('C:/certs/myCA.pem')
  }
});
connection.connect();
connection.query('SELECT * FROM NorthwindProducts', function(err, rows, fields) {
  if (err) throw err;
  console.log(rows);
});

connection.end();
