Epicor ERPData のPostgreSQL インターフェース

Epicor ERP 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Epicor ERP data にアクセスするには、CData JDBC Driver for Epicor ERP 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Epicor ERP data をクエリします。

JDBC データソースにEpicor ERP Data を設定

To connect to Epicor ERP 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.epicorerp.EpicorERPDriver

  • JDBC URL: The URL must start with "jdbc:epicorerp:" and can include any of the connection properties in name-value pairs separated with semicolons.

    To successfully connect to your ERP instance, you must specify the following connection properties:

    • Url:the URL of the server hosting your ERP instance. For example, https://myserver.EpicorSaaS.com
    • ERPInstance: the name of your ERP instance.
    • User: the username of your account.
    • Password: the password of your account.
    • Service: the service you want to retrieve data from. For example, BaqSvc.

    In addition, you may also set the optional connection properties:

    • ApiKey: An optional key that may be required for connection to some services depending on your account configuration.
    • ApiVersion: Defaults to v1. May be set to v2 to use the newer Epicor API.
    • Company: Required if you set the ApiVersion to v2.

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

    java -jar cdata.jdbc.epicorerp.jar

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

    A typical JDBC URL is below:

    jdbc:epicorerp:Service=Erp.BO.CustomerSvc;ERPInstance=MyInstance;URL=https://myaccount.epicorsaas.com;User=username;Password=password;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

Epicor ERP 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 Epicor ERP data:

  1. Log into your database.
  2. Load the extension for the database: CREATE EXTENSION jdbc2_fdw;
  3. Create a server object for Epicor ERP: CREATE SERVER EpicorERP FOREIGN DATA WRAPPER jdbc2_fdw OPTIONS ( drivername 'cdata.jdbc.epicorerp.EpicorERPDriver', url 'jdbc:epicorerp:Service=Erp.BO.CustomerSvc;ERPInstance=MyInstance;URL=https://myaccount.epicorsaas.com;User=username;Password=password;InitiateOAuth=GETANDREFRESH', querytimeout '15', jarfile '/home/MyUser/CData/CData\ JDBC\ Driver\ for\ Salesforce MyDriverEdition/lib/cdata.jdbc.epicorerp.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 EpicorERP OPTIONS ( username 'admin', password 'test');
  5. Create a foreign table in your local database: postgres=# CREATE FOREIGN TABLE customers ( customers_id text, customers_CustNum text, customers_Company numeric) SERVER EpicorERP OPTIONS ( table_name 'customers');
You can now execute read/write commands to Epicor ERP: postgres=# SELECT * FROM customers;
