Use the Remoting features of the WooCommerce JDBC Driver to create a PostgreSQL entry-point for data access.
There are a vast number of PostgreSQL clients available on the Internet. From standard Drivers to BI and Analytics tools, PostgreSQL is a popular interface for data access. Using our JDBC Drivers, you can now create PostgreSQL entry-points that you can connect to from any standard client.
To access WooCommerce data as a PostgreSQL database, use the CData JDBC Driver for WooCommerce and a JDBC foreign data wrapper (FDW). In this article, we compile the FDW, install it, and query WooCommerce data from PostgreSQL Server.
Connect to WooCommerce Data as a JDBC Data Source
To connect to WooCommerce as a JDBC data source, you will need the following:
- Driver JAR path: The JAR is located in the lib subfolder of the installation directory.
Driver class:
cdata.jdbc.woocommerce.WooCommerceDriver
- JDBC URL:
The URL must start with "jdbc:woocommerce:" and can include any of the connection properties in name-value pairs separated with semicolons.
WooCommerce supports the following authentication methods: one-legged OAuth1.0 Authentication and standard OAuth2.0 Authentication.
Connecting using one-legged OAuth 1.0 Authentication
Specify the following properties (NOTE: the below credentials are generated from WooCommerce settings page and should not be confused with the credentials generated by using WordPress OAuth2.0 plugin):
- ConsumerKey
- ConsumerSecret
Connecting using WordPress OAuth 2.0 Authentication
Build the JDBC Foreign Data Wrapper
The Foreign Data Wrapper can be installed as an extension to PostgreSQL, without recompiling PostgreSQL. The jdbc2_fdw extension is used as an example (downloadable here).
- Add a symlink from the shared object for your version of the JRE to /usr/lib/libjvm.so. For example:
ln -s /usr/lib/jvm/java-6-openjdk/jre/lib/amd64/server/libjvm.so /usr/lib/libjvm.so
- Start the build:
make install USE_PGXS=1
Query WooCommerce Data as a PostgreSQL Database
After you have installed the extension, follow the steps below to start executing queries to WooCommerce data:
- Log into your database.
-
Load the extension for the database:
CREATE EXTENSION jdbc2_fdw;
-
Create a server object for WooCommerce:
CREATE SERVER WooCommerce FOREIGN DATA WRAPPER jdbc2_fdw OPTIONS ( drivername 'cdata.jdbc.woocommerce.WooCommerceDriver', url 'jdbc:woocommerce:Url=https://example.com/; ConsumerKey=ck_ec52c76185c088ecaa3145287c8acba55a6f59ad; ConsumerSecret=cs_9fde14bf57126156701a7563fc87575713c355e5; InitiateOAuth=GETANDREFRESH', querytimeout '15', jarfile '/home/MyUser/CData/CData\ JDBC\ Driver\ for\ Salesforce MyDriverEdition/lib/cdata.jdbc.woocommerce.jar');
-
Create a user mapping for the username and password of a user known to the MySQL daemon.
CREATE USER MAPPING for postgres SERVER WooCommerce OPTIONS ( username 'admin', password 'test');
-
Create a foreign table in your local database:
postgres=# CREATE FOREIGN TABLE orders ( orders_id text, orders_ParentId text, orders_Total numeric) SERVER WooCommerce OPTIONS ( table_name 'orders');
postgres=# SELECT * FROM orders;
