MySQL ODBC Driver

The MySQL ODBC Driver is a powerful tool that allows you to connect with live MySQL data, directly from any applications that support ODBC connectivity.

Access MySQL databases from virtually anywhere through a standard ODBC Driver interface.



Use node-odbc to execute SQL queries against MySQL data from Node.js.

Node.js is a JavaScript runtime environment that allows you to run JavaScript code outside of a browser. With the CData ODBC Driver for MySQL, you can access live MySQL data from Node.js apps and scripts. In this article, we walk through installing node-odbc and the required tools to create a simple Node.js app with access to live MySQL data.

With built-in optimized data processing, the CData ODBC Driver offers unmatched performance for interacting with live MySQL data in Node.js. When you issue complex SQL queries from Node.js to MySQL, the driver pushes supported SQL operations, like filters and aggregations, directly to MySQL and utilizes the embedded SQL engine to process unsupported operations client-side (often SQL functions and JOIN operations).

Connecting to MySQL Data

If you have not already done so, provide values for the required connection properties in the data source name (DSN). You can use the built-in Microsoft ODBC Data Source Administrator to configure the DSN. This is also the last step of the driver installation. See the "Getting Started" chapter in the help documentation for a guide to using the Microsoft ODBC Data Source Administrator to create and configure a DSN.

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.

Building node-odbc

In order to connect to MySQL through the CData ODBC Driver, you need to build node-odbc manually (after installing the required tools).

Installing the Required Tools

The following commands install the tools required to build node-odbc (note the -g parameter, which installs the tools globally).

npm i -g windows-build-tools
npm i -g node-gyp

Building node-odbc

After installing the required tools, create a directory for the Node.js app and install odbc (which builds the binary for us to use in our Node.js script).

mkdir nodeodbc
cd nodeodbc
npm i -g node

Querying MySQL from Node.js

With the ODBC Driver installed, a DSN Configured, and node-odbc built, we are ready to query live MySQL data from a Node.js app. The sample code below connects to a specific DSN and queries the Orders table.

myscript.js

const odbc = require('odbc');

async function queryMySQL() {
    const connection = await odbc.connect(`DSN=CData MySQL Source`);
    const data = await connection.query('SELECT ShipName, Freight FROM Orders');
    console.log(data);
}

queryMySQL();

Once you write the app, use node to execute the script:

node myscript.js
