Exact Online ODBC Driver

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

Access Exact Online like you would a database - read, write, and update Accounts, Divisions, Opportunities, etc. through a standard ODBC Driver interface.



Use node-odbc to execute SQL queries against Exact Online 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 Exact Online, you can access live Exact Online 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 Exact Online data.

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

Connecting to Exact Online 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.

Exact Online uses the OAuth authentication standard. You can use the embedded OAuth credentials or you can register an OAuth app with Exact to obtain your own. In addition to the OAuth values, provide the Region. If Division is not set, the default Division is determined.

See the "Getting Started" chapter of the help documentation for more information.

Building node-odbc

In order to connect to Exact Online 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 Exact Online from Node.js

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

myscript.js

const odbc = require('odbc');

async function queryExactOnline() {
    const connection = await odbc.connect(`DSN=CData ExactOnline Source`);
    const data = await connection.query('SELECT Name, CreditLinePurchase FROM Accounts');
    console.log(data);
}

queryExactOnline();

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

node myscript.js
