JRuby からDynamics NAV Data にデータ連携

リアルタイムDynamics NAV data に連携するシンプルなJRuby アプリケーションを作成します。

JRuby はRuby プログラミング言語の高性能で安定した、完全にスレッド化されたJava 実装です。CData JDBC Driver for Dynamics NAV を使用すると、JRuby からリアルタイムDynamics NAV data へのデータ連携を簡単に実装できます。ここでは、Dynamics NAV data に接続し、クエリを実行して結果を表示する簡単なJRuby アプリを作成する方法を説明します。

Dynamics NAV Data にJDBC で接続

Before creating the app, note the installation location for the JAR file for the JDBC Driver (typically C:\Program Files\CDatat\CData JDBC Driver for Dynamics NAV\lib).

JRuby natively supports JDBC, so you can easily connect to Dynamics NAV and execute SQL queries.Initialize the JDBC connection with the getConnection function of the java.sql.DriverManager class.

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.

Below is a typical JDBC connection string for Dynamics NAV:

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

Dynamics NAV Data への接続性を持つJRuby アプリを作成

Create a new Ruby file (for example: DynamicsNAVSelect.rb) and open it in a text editor.Copy the following code into your file:

require 'java' require 'rubygems' require 'C:/Program Files/CData/CData JDBC Driver for Dynamics NAV 2018/lib/cdata.jdbc.dynamicsnav.jar' url = "jdbc:dynamicsnav:http://myserver:7048;User=myserver\Administrator;Password=admin;ServerInstance=DYNAMICSNAV71;" conn = java.sql.DriverManager.getConnection(url) stmt = conn.createStatement rs = stmt.executeQuery("SELECT Name, Prices_Including_VAT FROM Customer") while (rs.next) do puts rs.getString(1) + ' ' + rs.getString(2) end

With the file completed, you are ready to display your Dynamics NAV data with JRuby.To do so, simply run your file from the command line:

jruby -S DynamicsNAVSelect.rb

Writing SQL-92 queries to Dynamics NAV allows you to quickly and easily incorporate Dynamics NAV data into your own JRuby applications.Download a free trial today!
