Connect to Azure Synapse Data and Transfer Data in Talend

This article shows how you can easily integrate the CData JDBC driver for Azure Synapse into your workflow in Talend. This article uses the CData JDBC Driver for Azure Synapse to transfer Azure Synapse data in a job flow in Talend.

Connect to Azure Synapse in Talend as a JDBC Data Source

You can follow the procedure below to establish a JDBC connection to Azure Synapse:

1. Add a new database connection to Azure Synapse data: To add a new connection, expand the Metadata node, right-click the Db Connections node, and then click Create Connection.
2. In the resulting wizard, enter a name for the connection.

3. On the next page, select Generic JDBC from the DB Type menu and 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;
4. Enter the path to the cdata.jdbc.azuresynapse.jar file, located in the lib subfolder of the installation directory.
5. Right-click the connection and then click Retrieve Schema.
6. Click Next with the default options to select the tables you want to import.
7. Finish the wizard with the default options.

Output the Products Table to a Flat File

You can follow the procedure below to transfer the Products table to a flat file output component:

1. In the Table Schemas node, drag the tables to the workspace.
2. In the dialog that is displayed, select the tJDBCInput component.
3. Next, drag a tFileOutputDelimited component from the Business Intelligence tab of the Palette into the workspace.
4. Right-click the Products tJDBCInput component and drag a vector to the output file.

Run the project to transfer the data.
