JRuby からDynamics GP Data にデータ連携

リアルタイムDynamics GP 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 GP を使用すると、JRuby からリアルタイムDynamics GP data へのデータ連携を簡単に実装できます。ここでは、Dynamics GP 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 GP 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 GP\lib).

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

To authenticate set the User and Password connection properties.

To connect set the URL to the Web services endpoint; for example, http://{servername}:{port}/Dynamics/GPService. Additionally, set CompanyId; you can obtain this value in the company setup window: Click Tools -> Setup -> Company.

By default, data summaries are not returned to save performance. Set LookupIds to true to return details such as line items; however, note that entities must be retrieved one at a time.

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

java -jar cdata.jdbc.dynamicsgp.jar

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

Below is a typical JDBC connection string for Dynamics GP:

jdbc:dynamicsgp:CompanyId=mycompanyId;user=myuser;password=mypassword;URL= http://{servername}:{port}/Dynamics/GPService;

Dynamics GP Data への接続性を持つJRuby アプリを作成

Create a new Ruby file (for example: DynamicsGPSelect.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 GP 2018/lib/cdata.jdbc.dynamicsgp.jar' url = "jdbc:dynamicsgp:CompanyId=mycompanyId;user=myuser;password=mypassword;URL= http://{servername}:{port}/Dynamics/GPService;" conn = java.sql.DriverManager.getConnection(url) stmt = conn.createStatement rs = stmt.executeQuery("SELECT CustomerName, TotalAmount FROM SalesInvoice") while (rs.next) do puts rs.getString(1) + ' ' + rs.getString(2) end

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

jruby -S DynamicsGPSelect.rb

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