Query Dotmailer Data through ODBC in Node.js

Node.js is a JavaScript runtime environment that allows you to run JavaScript code outside of a browser. With the CData API Driver for ODBC, you can access live Dotmailer 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 Dotmailer data.

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

Connecting to Dotmailer 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.

Start by setting the Profile connection property to the location of the Dotmailer Profile on disk (e.g. C:\profiles\Dotmailer.apip). Next, set the ProfileSettings connection property to the connection string for Dotmailer (see below).

Dotmailer API Profile Settings

Create an API user in the Dotdigital platform under Setup > Access > API Users > New User. Your RegionId can be found in your account URL (e.g.,

r1

r1.dotdigitalgroup.com

Building node-odbc

In order to connect to Dotmailer 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 Dotmailer from Node.js

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

myscript.js

const odbc = require('odbc');

async function queryAPI() {
    const connection = await odbc.connect(`DSN=CData API Source`);
    const data = await connection.query('SELECT Name, Type FROM Account');
    console.log(data);
}

queryAPI();

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

node myscript.js
