CData Connect



Execute MySQL queries against IBM Cloud SQL Query data from Node.js.

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

CData Connect Cloud provides a pure MySQL, cloud-to-cloud interface for IBM Cloud SQL Query, allowing you to easily query live IBM Cloud SQL Query 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 IBM Cloud SQL Query, leveraging server-side processing to quickly return IBM Cloud SQL Query data.

Create a Virtual MySQL Database for IBM Cloud SQL Query 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 "IBM Cloud SQL Query" from Available Data Sources.
  3. Enter the necessary authentication properties to connect to IBM Cloud SQL Query.

    IBM Cloud SQL uses the OAuth and HMAC authentication standards. See the "Getting Started" chapter of the help documentation for a guide to using OAuth.

  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 IBM Cloud SQL Query data from any MySQL client.

Query IBM Cloud SQL Query from Node.js

The following example shows how to define a connection and execute queries to IBM Cloud SQL Query 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 IBM Cloud SQL Query (ibmcloudsqldb)

Connect to IBM Cloud SQL Query 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 : 'ibmcloudsqldb',
  port	   : '3306',
  user     : 'admin',
  password : 'password',
  ssl      : {
    ca : fs.readFileSync('C:/certs/myCA.pem')
  }
});
connection.connect();
connection.query('SELECT * FROM Jobs', function(err, rows, fields) {
  if (err) throw err;
  console.log(rows);
});

connection.end();
