Query PCA Sales Data as a SQL Server in Node.js

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

CData Connect Server provides a pure SQL Server interface for PCA Sales, allowing you to easily build reports from live PCA Sales 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 PCA Sales, leveraging server-side processing to quickly return the requested PCA Sales data.

Create a Virtual SQL Server Database for PCA Sales 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 "PCA Sales" from Available Data Sources.
3. Enter the necessary authentication properties to connect to PCA Sales.

   In order to authenticate using the OAuth, specify the following:

   • AuthScheme: Set to OAuth.

   In order to authenticate using the OAuth Password, specify the following:

   • AuthScheme: Set to OAuthPassword.
   • User: Enter the PCA Sales username.
   • Password: Enter the PCA Sales password.
   • ServiceId: Enter the Service ID used to connect tot he PCA API server.
   • ServicePassword: Enter the Service Password for the above Service ID.

   For both authentication methods, specify the following:

   • Data Center: Enter the name for the PCA API Server.
   • Default Data Area: Enter the data area to which you want to connect.
   • Product Code: Enter "Kon20" or "Acc20."

   For more information, refer to 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 PCA Sales data from Node.js.

Query PCA Sales from Node.js

The following example shows how to define a connection and execute queries to PCA Sales 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 PCA Sales (PCASales1)

Connect to PCA Sales 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: 'PCASales1',
    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);
    }
}
