Dynamics NAVData のPostgreSQL インターフェース

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

JDBC データソースにDynamics NAV Data を設定

To connect to Dynamics NAV 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.dynamicsnav.DynamicsNAVDriver

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

    Before you can connect, OData Services will need to be enabled on the server. Once OData Services are enabled, you will be able to query any Services that are published on the server.

    The User and Password properties, under the Authentication section, must be set to valid Dynamics NAV user credentials. In addition, you will need to specify a URL to a valid Dynamics NAV server organization root and a ServerInstance. If there is not a Service Default Company for the server, you will need to set the Company as well.

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

    java -jar cdata.jdbc.dynamicsnav.jar

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

    A typical JDBC URL is below:

    jdbc:dynamicsnav:http://myserver:7048;User=myserver\Administrator;Password=admin;ServerInstance=DYNAMICSNAV71;

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

Dynamics NAV 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 Dynamics NAV data:

  1. Log into your database.
  2. Load the extension for the database: CREATE EXTENSION jdbc2_fdw;
  3. Create a server object for Dynamics NAV: CREATE SERVER DynamicsNAV FOREIGN DATA WRAPPER jdbc2_fdw OPTIONS ( drivername 'cdata.jdbc.dynamicsnav.DynamicsNAVDriver', url 'jdbc:dynamicsnav:http://myserver:7048;User=myserver\Administrator;Password=admin;ServerInstance=DYNAMICSNAV71;', querytimeout '15', jarfile '/home/MyUser/CData/CData\ JDBC\ Driver\ for\ Salesforce MyDriverEdition/lib/cdata.jdbc.dynamicsnav.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 DynamicsNAV OPTIONS ( username 'admin', password 'test');
  5. Create a foreign table in your local database: postgres=# CREATE FOREIGN TABLE customer ( customer_id text, customer_Name text, customer_Prices_Including_VAT numeric) SERVER DynamicsNAV OPTIONS ( table_name 'customer');
You can now execute read/write commands to Dynamics NAV: postgres=# SELECT * FROM customer;
