Query Oracle Eloqua 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 ODBC Driver for Eloqua, you can access live Oracle Eloqua 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 Oracle Eloqua data.

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

Connecting to Oracle Eloqua 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.

There are two authentication methods available for connecting to Oracle Eloqua: Login and OAuth. The Login method requires you to have the Company, User, and Password of the user.

If you do not have access to the username and password or do not wish to require them, you can use OAuth authentication. OAuth is better suited for allowing other users to access their own data. Using login credentials is better suited for accessing your own data.

Building node-odbc

In order to connect to Oracle Eloqua 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 Oracle Eloqua from Node.js

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

myscript.js

const odbc = require('odbc');

async function queryOracleEloqua() {
    const connection = await odbc.connect(`DSN=CData OracleEloqua Source`);
    const data = await connection.query('SELECT Name, ActualCost FROM Campaign');
    console.log(data);
}

queryOracleEloqua();

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

node myscript.js
