Get the Report →Query MySQL Data as a SQL Server Database in Node.js
Execute SQL Server queries against MySQL data from Node.js.
You can use CData Connect Cloud to query MySQL data through a SQL Server interface. Follow the procedure below to create a virtual database for MySQL in Connect Cloud and start querying using Node.js.
CData Connect Cloud provides a pure MySQL, cloud-to-cloud interface for MySQL, allowing you to easily query live MySQL 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 MySQL, leveraging server-side processing to quickly return MySQL data.
Configure MySQL Connectivity for NodeJS
Connectivity to MySQL from NodeJS is made possible through CData Connect Cloud. To work with MySQL data from NodeJS, we start by creating and configuring a MySQL connection.
- Log into Connect Cloud, click Connections and click Add Connection
- Select "MySQL" from the Add Connection panel
-
Enter the necessary authentication properties to connect to MySQL.
The Server and Port properties must be set to a MySQL server. If IntegratedSecurity is set to false, then User and Password must be set to valid user credentials. Optionally, Database can be set to connect to a specific database. If not set, tables from all databases will be returned.
- Click Create & Test
- Navigate to the Permissions tab in the Add MySQL Connection page and update the User-based permissions.
Add a Personal Access Token
If you are connecting from a service, application, platform, or framework that does not support OAuth authentication, you can create a Personal Access Token (PAT) to use for authentication. Best practices would dictate that you create a separate PAT for each service, to maintain granularity of access.
- Click on your username at the top right of the Connect Cloud app and click User Profile.
- On the User Profile page, scroll down to the Personal Access Tokens section and click Create PAT.
- Give your PAT a name and click Create.
- The personal access token is only visible at creation, so be sure to copy it and store it securely for future use.
With the connection configured, you are ready to connect to MySQL data from Node.js.
Query MySQL from Node.js
The following example shows how to define a connection and execute queries to MySQL with the SQL Server module. You will need the following information:
- server: tds.cdata.com
- port: 14333
- user: a Connect Cloud user (e.g. user@mydomain.com)
- password: the PAT for the above user
- database: The connection you configured for MySQL (MySQL1)
Connect to MySQL data and start executing queries with the code below:
var sql = require('mssql') var config = { server: 'tds.cdata.com', port: 14333, user: 'user@mydomain.com', //update me password: 'CONNECT_USER_PAT', //update me options: { encrypt: true, database: 'MySQL1' } } sql.connect(config, err => { if(err){ throw err ; } new sql.Request().query('SELECT * FROM Orders', (err, result) => { console.dir(result) }) }); sql.on('error', err => { console.log("SQL Error: " ,err); })
