WooCommerceData のPostgreSQL インターフェース

WooCommerce JDBC Driver のRemoting 機能を使用して、データアクセス用のPostgreSQL エントリポイントを作成します。

インターネット上には利用可能な膨大な数のPostgreSQL クライアントがあります。標準のドライバーからBI および分析ツールまで、PostgreSQL はデータアクセスのための人気の高いインタフェースです。 JDBC ドライバーを使用して、標準クライアントから接続できるPostgreSQL エントリポイントを作成することができます。

PostgreSQL データベースとしてWooCommerce data にアクセスするには、CData JDBC Driver for WooCommerce とJDBC 外部データラッパー(FDW)を使用します。ここでは、FDW をコンパイルしてインストールし、PostgreSQL サーバーからWooCommerce data をクエリします。

JDBC データソースにWooCommerce Data を設定

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

    After having configured the plugin, you may connect to WooCommerce by providing the following connection properties:

    • OAuthClientId
    • OAuthClientSecret
    • CallbackURL
    • InitiateOAuth - Set this to either GETANDREFRESH or REFRESH

    In either case, you will need to set the Url property to the URL of the WooCommerce instance.

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

    java -jar cdata.jdbc.woocommerce.jar

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

    A typical JDBC URL is below:

    jdbc:woocommerce:Url=https://example.com/; ConsumerKey=ck_ec52c76185c088ecaa3145287c8acba55a6f59ad; ConsumerSecret=cs_9fde14bf57126156701a7563fc87575713c355e5; InitiateOAuth=GETANDREFRESH

JDBC Foreign Data Wrapper をビルド

The Foreign Data Wrapper can be installed as an extension to PostgreSQL, without recompiling PostgreSQL.The jdbc2_fdw extension is used as an example.

  1. 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
  2. Start the build: make install USE_PGXS=1

WooCommerce Data をPostgreSQL データベースとしてクエリ

After you have installed the extension, follow the steps below to start executing queries to WooCommerce data:

  1. Log into your database.
  2. Load the extension for the database: CREATE EXTENSION jdbc2_fdw;
  3. 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');
  4. 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');
  5. 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');
You can now execute read/write commands to WooCommerce: postgres=# SELECT * FROM orders;
