Connect to WordPress Data in CloverDX (formerly CloverETL)

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

Connect to WordPress as a JDBC Data Source

1. Create the connection to WordPress 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.wordpress.jar file.
3. Enter the JDBC URL.

   To connect to WordPress, set the URL property and other authentication properties. WordPress supports Basic (User and Password) and OAuth2.0 authentication, though Basic is recommended for a testing environment only. To connect with OAuth you will need to register an app with WordPress.

   See the Getting Started guide in the CData driver documentation for more information.

   Built-in Connection String Designer

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

   java -jar cdata.jdbc.wordpress.jar

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

   A typical JDBC URL is below:

   jdbc:wordpress:Url=http://www.yourwordpresshost.com;InitiateOAuth=GETANDREFRESH

Query WordPress 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 WordPress JDBC data source from the drop-down menu.
3. Enter the SQL query. For example: SELECT Id, Name FROM Categories

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 Categories table. (You can also open this menu by right-clicking the input port for the UniversalDataWriter.)
6. Click Run to write to the file.
