Transfer Azure Synapse data using the visual workflow in the CloverDX data integration tool.
The CData JDBC Driver for Azure Synapse enables you to use the data transformation components in CloverDX (formerly CloverETL) to work with Azure Synapse as sources and destinations. In this article, you will use the JDBC Driver for Azure Synapse to set up a simple transfer into a flat file.

Connect to Azure Synapse as a JDBC Data Source
- Create the connection to Azure Synapse data. In a new CloverDX graph, right-click the Connections node in the Outline pane and click Connections -> Create Connection. The Database Connection wizard is displayed.
- Click the plus icon to load a driver from a JAR. Browse to the lib subfolder of the installation directory and select the cdata.jdbc.azuresynapse.jar file.
- Enter the JDBC URL.
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.
A typical JDBC URL is below:
jdbc:azuresynapse:User=myuser;Password=mypassword;Server=localhost;Database=Northwind;
Query Azure Synapse Data with the DBInputTable Component
- Drag a DBInputTable from the Readers selection of the Palette onto the job flow and double-click it to open the configuration editor.
- In the DB connection property, select the Azure Synapse JDBC data source from the drop-down menu.
- Enter the SQL query. For example:
SELECT Id, ProductName FROM Products WHERE ProductName = 'Konbu'
Write the Output of the Query to a UniversalDataWriter
- Drag a UniversalDataWriter from the Writers selection onto the jobflow.
- Double-click the UniversalDataWriter to open the configuration editor and add a file URL.
- Right-click the DBInputTable and then click Extract Metadata.
- Connect the output port of the DBInputTable to the UniversalDataWriter.
- In the resulting Select Metadata menu for the UniversalDataWriter, choose the Products table. (You can also open this menu by right-clicking the input port for the UniversalDataWriter.)
- Click Run to write to the file.
