Azure Synapse JDBC Driver

Rapidly create and deploy powerful Java applications that integrate with Azure Synapse.



Create a simple Mule Application that uses HTTP and SQL with the CData JDBC Driver for Azure Synapse to create a JSON endpoint for Azure Synapse data.

The CData JDBC Driver for Azure Synapse connects Azure Synapse data to Mule applications enabling read , write, update, and delete functionality with familiar SQL queries. The JDBC Driver allows users to easily create Mule applications to backup, transform, report, and analyze Azure Synapse data.

This article demonstrates how to use the CData JDBC Driver for Azure Synapse inside of a Mule project to create a Web interface for Azure Synapse data. The application created allows you to request Azure Synapse data using an HTTP request and have the results returned as JSON. The exact same procedure outlined below can be used with any CData JDBC Driver to create a Web interface for the 200+ available data sources.

  1. Create a new Mule Project in Anypoint Studio.
  2. Add an HTTP Connector to the Message Flow.
  3. Configure the address for the HTTP Connector.
  4. Add a Database Select Connector to the same flow, after the HTTP Connector.
  5. Create a new Connection (or edit an existing one) and configure the properties.
    • Set Connection to "Generic Connection"
    • Select the CData JDBC Driver JAR file in the Required Libraries section (e.g. cdata.jdbc.azuresynapse.jar).
    • Set the URL to the connection string for Azure Synapse

      Connecting to Azure Synapse

      In addition to providing authentication (see below), set the following properties to connect to a Azure Synapse database:

      • Server: The server running Azure. You can find this by logging into the Azure portal and navigating to Azure Synapse Analytics -> Select your database -> Overview -> Server name.
      • Database: The name of the database, as seen in the Azure portal on the Azure Synapse Analytics page.

      Authenticating to Azure Synapse

      Connect to Azure Synapse using the following properties:

      • User: The username provided for authentication with Azure.
      • Password: The password associated with the authenticating user.

      Built-in Connection String Designer

      For assistance in constructing the JDBC URL, use the connection string designer built into the Azure Synapse JDBC Driver. Either double-click the JAR file or execute the jar file from the command-line.

      java -jar cdata.jdbc.azuresynapse.jar

      Fill in the connection properties and copy the connection string to the clipboard.

    • Set the Driver class name to cdata.jdbc.azuresynapse.AzureSynapseDriver.
    • Click Test Connection.
  6. Set the SQL Query Text to a SQL query to request Azure Synapse data. For example: SELECT Id, ProductName FROM Products WHERE ProductName = 'Konbu'
  7. Add a Transform Message Component to the flow.
  8. Set the Output script to the following to convert the payload to JSON:
    %dw 2.0
    output application/json
    ---
    payload
            
  9. To view your Azure Synapse data, navigate to the address you configured for the HTTP Connector (localhost:8081 by default): http://localhost:8081. The Azure Synapse data is available as JSON in your Web browser and any other tools capable of consuming JSON endpoints.

At this point, you have a simple Web interface for working with Azure Synapse data (as JSON data) in custom apps and a wide variety of BI, reporting, and ETL tools. Download a free, 30 day trial of the JDBC Driver for Azure Synapse and see the CData difference in your Mule Applications today.
