Connect to Azure Analysis Services Data and Transfer Data in Talend

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

Connect to Azure Analysis Services in Talend as a JDBC Data Source

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

1. Add a new database connection to Azure Analysis Services 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.

   To connect to Azure Analysis Services, set the Url property to a valid server, for instance, asazure://southcentralus.asazure.windows.net/server, in addition to authenticating. Optionally, set Database to distinguish which Azure database on the server to connect to.

   Azure Analysis Services uses the OAuth authentication standard. OAuth requires the authenticating user to interact with Azure Analysis Services using the browser. You can connect without setting any connection properties for your user credentials. See the Help documentation for more information.

   Built-in Connection String Designer

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

   java -jar cdata.jdbc.aas.jar

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

   A typical JDBC URL is below:

   jdbc:aas:URL=asazure://REGION.asazure.windows.net/server;InitiateOAuth=GETANDREFRESH
4. Enter the path to the cdata.jdbc.aas.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 Customer Table to a Flat File

You can follow the procedure below to transfer the Customer 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 Customer tJDBCInput component and drag a vector to the output file.

Run the project to transfer the data.
