How to Connect a Local SQL Server Database to Azure Synapse?

In today's data-driven world, businesses rely on powerful data analytics and insights to make informed decisions. Azure Synapse Analytics, formerly known as Azure SQL Data Warehouse, is Microsoft's cloud-based data integration and analytics service that allows organizations to gain deep insights from their data. But what if you already have an existing SQL Server database running on-premises and want to leverage the capabilities of Azure Synapse? In this blog post, we will walk you through the steps to connect a local SQL Server database to Azure Synapse, enabling you to harness the full potential of cloud-based data analytics.

What is Azure Synapse?

Before diving into the connection process, let's briefly understand what Azure Synapse is. Azure Synapse is an integrated analytics service that combines big data and data warehousing capabilities. It enables users to ingest, prepare, manage, and serve data for immediate business intelligence and machine learning needs. With built-in integration with Power BI and Azure Machine Learning, Azure Synapse empowers organizations to unlock insights and gain a competitive advantage.


Before you begin the connection process, make sure you have the following prerequisites:

  1. A local SQL Server database: Ensure that you have a SQL Server instance running locally and accessible from the network.
  2. Azure Synapse workspace: Create an Azure Synapse workspace in your Azure portal. This will be your destination to connect the local SQL Server database.

Steps to Connect a Local SQL Server Database to Azure Synapse

Step 1: Set up an Azure Data Gateway

Azure Synapse requires a secure connection between your on-premises SQL Server and the Azure cloud. To establish this connection, you need to set up an Azure Data Gateway. The Azure Data Gateway acts as a bridge, securely connecting your local SQL Server to the Azure Synapse workspace.

  1. Go to your Azure Synapse workspace in the Azure portal.
  2. Under the "Manage" section, click on "Linked Services."
  3. Click on the "New" button to create a new linked service.
  4. Choose "Integration runtime" as the type and provide a name for the integration runtime.
  5. Select "Self-hosted" as the deployment model.
  6. Download and install the Azure Data Gateway on your local machine where the SQL Server is hosted. Follow the installation instructions provided during the setup process.
  7. After installation, configure the gateway with your Azure account credentials.

Step 2: Configure a Linked Service

With the Azure Data Gateway in place, it's time to configure a linked service to establish the connection to your local SQL Server.

  1. In the Azure Synapse workspace, go to "Linked Services" and click on "New."
  2. Choose "SQL Server" as the type for the linked service.
  3. Provide a name for the linked service and select the integration runtime you previously created.
  4. Enter the connection details for your local SQL Server database, including server name, database name, authentication method, and credentials.

Step 3: Create a Data Pipeline

Now that you have set up the linked service, it's time to create a data pipeline to move data from your local SQL Server to Azure Synapse.

  1. In your Azure Synapse workspace, navigate to "Pipelines" and click on "New pipeline."
  2. Use the drag-and-drop interface to add a source (your local SQL Server database) and a sink (Azure Synapse).
  3. Select the linked service you created for both the source and sink.
  4. Define the data mapping and transformations as needed.

Step 4: Run the Data Pipeline

Once you've configured the data pipeline, you are ready to run it and start moving data from your local SQL Server database to Azure Synapse.

  1. Validate the pipeline to ensure there are no errors or issues.
  2. Click on "Publish" to publish the pipeline.
  3. Click on "Trigger now" to manually trigger the pipeline and start the data movement.

Step 5: Monitor and Analyze Data in Azure Synapse

After the data pipeline has run successfully, you can start exploring and analyzing the data in Azure Synapse. Utilize the powerful analytics capabilities of Azure Synapse to gain insights and generate reports for better decision-making.


Connecting your local SQL Server database to Azure Synapse opens up a world of opportunities for data-driven insights and analytics. By following the steps outlined in this guide, you can securely establish the connection through the Azure Data Gateway and create data pipelines to move and analyze data seamlessly.

Azure Synapse provides a powerful platform for businesses to gain a competitive edge by harnessing the power of cloud-based data analytics. With its integrated data warehousing and big data capabilities, you can turn raw data into valuable insights that drive strategic decision-making.

As you embark on your journey with Azure Synapse, continue to explore its features and capabilities to make the most of this powerful data analytics service. Stay curious, keep learning, and uncover the full potential of your data with Azure Synapse!
