Azure Analysis Services JDBC Driver

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



Transfer Azure Analysis Services data using the visual workflow in the CloverDX data integration tool.

The CData JDBC Driver for Azure Analysis Services enables you to use the data transformation components in CloverDX (formerly CloverETL) to work with Azure Analysis Services as sources. In this article, you will use the JDBC Driver for Azure Analysis Services to set up a simple transfer into a flat file.

Connect to Azure Analysis Services as a JDBC Data Source

  1. Create the connection to Azure Analysis Services 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.
  2. 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.aas.jar file.
  3. 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

Query Azure Analysis Services Data with the DBInputTable Component

  1. Drag a DBInputTable from the Readers selection of the Palette onto the job flow and double-click it to open the configuration editor.
  2. In the DB connection property, select the Azure Analysis Services JDBC data source from the drop-down menu.
  3. Enter the SQL query. For example: SELECT Country, Education FROM Customer WHERE Country = 'Australia'

Write the Output of the Query to a UniversalDataWriter

  1. Drag a UniversalDataWriter from the Writers selection onto the jobflow.
  2. Double-click the UniversalDataWriter to open the configuration editor and add a file URL.
  3. Right-click the DBInputTable and then click Extract Metadata.
  4. Connect the output port of the DBInputTable to the UniversalDataWriter.
  5. In the resulting Select Metadata menu for the UniversalDataWriter, choose the Customer table. (You can also open this menu by right-clicking the input port for the UniversalDataWriter.)
  6. Click Run to write to the file.
