CData Connect



Execute MySQL queries against Tally data from Node.js.

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

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

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

    Set the following connection properties to connect to Tally Instance:

    • Url: Set this to the URL for your Tally instance. For example: http://localhost:9000.
  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 Tally data from any MySQL client.

Query Tally from Node.js

The following example shows how to define a connection and execute queries to Tally 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 Tally (tallydb)

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

connection.end();
