Azure Analysis Services Icon Azure Analysis Services ODBC Driver

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

Access Azure Analysis Services data like you would a database - read, write, and update Azure Analysis Services AnalysisServicesData, etc. through a standard ODBC Driver interface.

Query Azure Analysis Services Data through ODBC in Node.js



Use node-odbc to execute SQL queries against Azure Analysis Services 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 Azure Analysis Services, you can access live Azure Analysis Services 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 Azure Analysis Services data.

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

Connecting to Azure Analysis Services 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.

To connect to Azure Analysis Services, set the Url property to a valid server, for instance, asazure://southcentralus.asazure.windows.net/server, in addition to authenticating. Optionally, set Database to distinguish which Azure database on the server to connect to.

Azure Analysis Services uses the OAuth authentication standard. OAuth requires the authenticating user to interact with Azure Analysis Services using the browser. You can connect without setting any connection properties for your user credentials. See the Help documentation for more information.

Building node-odbc

In order to connect to Azure Analysis Services 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 Azure Analysis Services from Node.js

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

myscript.js

const odbc = require('odbc');

async function queryAAS() {
    const connection = await odbc.connect(`DSN=CData AAS Source`);
    const data = await connection.query('SELECT Country, Education FROM Customer');
    console.log(data);
}

queryAAS();

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

node myscript.js
