Query SAS Data Sets Data as a SQL Server in Node.js



Execute SQL Server queries against SAS Data Sets data from Node.js.

You can use CData Connect Server to query SAS Data Sets data through a SQL Server interface. Follow the procedure below to create a virtual database for SAS Data Sets in Connect Server and start querying using Node.js.

CData Connect Server provides a pure SQL Server interface for SAS Data Sets, allowing you to easily build reports from live SAS Data Sets data in Node.js — without replicating the data to a natively supported database. As you build visualizations, Node.js generates SQL queries to gather data. Using optimized data processing out of the box, CData Connect Server pushes all supported SQL operations (filters, JOINs, etc) directly to SAS Data Sets, leveraging server-side processing to quickly return the requested SAS Data Sets data.

Create a Virtual SQL Server Database for SAS Data Sets Data

CData Connect Server uses a straightforward, point-and-click interface to connect to data sources and generate APIs.

  1. Login to Connect Server and click Connections.
  2. Select "SAS Data Sets" from Available Data Sources.
  3. Enter the necessary authentication properties to connect to SAS Data Sets.

    Set the following connection properties to connect to your SAS DataSet files:

    Connecting to Local Files

    • Set the Connection Type to "Local." Local files support SELECT, INSERT, and DELETE commands.
    • Set the URI to a folder containing SAS files, e.g. C:\PATH\TO\FOLDER\.

    Connecting to Cloud-Hosted SAS DataSet Files

    While the driver is capable of pulling data from SAS DataSet files hosted on a variety of cloud data stores, INSERT, UPDATE, and DELETE are not supported outside of local files in this driver.

    Set the Connection Type to the service hosting your SAS DataSet files. A unique prefix at the beginning of the URI connection property is used to identify the cloud data store and the remainder of the path is a relative path to the desired folder (one table per file) or single file (a single table). For more information, refer to the Getting Started section of the Help documentation.

  4. Click Save Changes
  5. Click Privileges -> Add and add the new user (or an existing user) with the appropriate permissions.

With the virtual database created, you are ready to connect to SAS Data Sets data from Node.js.

Query SAS Data Sets from Node.js

The following example shows how to define a connection and execute queries to SAS Data Sets with the SQL Server module. You will need the following information:

  • Host name, or address, and port: The address of your Connect Server instance and the port (1433)
  • Username and password: The username and password of a user you authorized on Connect Server
  • Database name: The database you configured for SAS Data Sets (SASDataSets1)

Connect to SAS Data Sets data and start executing queries with the code below:

const sql = require('mssql');

const config = {
    user: 'your_connect_username', 
    password: 'your_connect_password', 
    server: 'connect_server_url', 
    port: 1433, // optional, defaults to 1433
    database: 'SASDataSets1',
    authentication: {
        type: 'default'
    },
    options: {
        encrypt: true
    }
}

console.log("Starting...");
connectAndQuery();

async function connectAndQuery() {
    try {
        var poolConnection = await sql.connect(config);

        console.log("Reading rows from the table...");
        var resultSet = await poolConnection.request().query(`SELECT * FROM table_name`);

        console.log(`${resultSet.recordset.length} rows returned.`);

        // output column headers
        var columns = "";
        for (var column in resultSet.recordset.columns) {
            columns += column + ", ";
        }
        console.log("%s	", columns.substring(0, columns.length - 2));

        // ouput row contents from default record set
        resultSet.recordset.forEach(row => {
            console.log("%s	%s", row.CategoryName, row.ProductName);
        });

        // close connection only when we're certain application is finished
        poolConnection.close();
    } catch (err) {
        console.error(err.message);
    }
}
