Query xBase Data as a MySQL Database in Node.js

Execute MySQL queries against xBase data from Node.js.

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

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

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

    The DataSource property must be set to the name of the folder that contains the .dbf files. Specify the IncludeFiles property to work with xBase table files having extensions that differ from .dbf. Specify multiple extensions in a comma-separated list.

  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 xBase data from any MySQL client.

Query xBase from Node.js

The following example shows how to define a connection and execute queries to xBase 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 xBase (xbasedb)

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

connection.end();
