Published:22 September 2022 - 7 min. read

Azure Cloud Labs: these FREE, on‑demand Azure Cloud Labs will get you into a real‑world environment and account, walking you through step‑by‑step how to best protect, secure, and recover Azure data.

If you are stressing over data analysis and manually carrying out query statements or manual imports, why not consider using the Power BI Data Gateway? With Power BI Data Gateway, you can simplify and virtualize data analysis.

In this tutorial, you will learn how to set up data sources seamlessly and efficiently using Azure SQL Server and On-premises data gateway.

Improve your day-to-day data visualization by connecting sources to your Power BI Data Gateway!

Prerequisites

This tutorial will be a hands-on demonstration. To follow along, be sure you have the following:

  • Power BI installed on your local machine, the version in this tutorial is 2.97.

Connecting On-premises to Power Bi Data Gateway

On-premises data gateway bridges the gap between Power-Bi and cloud-related apps or software, creating a path where you can securely move your data from one end to another. Although the gateway is not responsible for transferring data, the gateway creates a server or a medium to transfer your data.

Before connecting the on-premises data gateway to Power BI, you must install the standard gateway on your local machine.

Check the requirements for On-Premises Gateway installation.

1. Download the standard gateway file, and open the installer once downloaded.

2. Next, provide the email address you want to connect to the gateway and click Sign In. Ensure the email address is the same as the one connected to your Power Bi account.

4. Now, configure the on-premises data gateway with the following:

  • Provide an on-premises data gateway name.

Optionally, tick the Add to an existing gateway cluster box to add the data gateway to an existing cluster.

  • Provide, and confirm a Recovery key that consists of a minimum of eight characters. This key is stored and used to verify your ownership when you lose access to the on-premises gateway.
  • Click Configure to save your settings and set up your created on-premises data gateway.

Connecting Azure SQL Database to Power BI

By connecting Azure and Power BI, you can perform data processing into analytics and report that provides real-time insight into any business or company. They both can develop complex business and intellectual solutions using built-in connectivity.

Don’t worry. You don’t need to write code to connect Azure tools and software to Power BI.

1. On the Azure Portal, search for Azure SQL and select the Azure SQL service that comes up to access Azure SQL.

Creating Data in Azure SQL Database to Visualize

You now have an Azure SQL database and a server, and you’re ready to dig into creating data or querying the database to visualize on Power BI. The Azure SQL server offers a query editor that lets you write queries, create tables, and add data to created tables.

To start creating data in Azure SQL database:

1. On your resource’s dashboard, click Query editor to add a query.
