JRuby からLohaco Data にデータ連携

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

Lohaco 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 Lohaco\lib).

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

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

java -jar cdata.jdbc.lohaco.jar

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

Below is a typical JDBC connection string for Lohaco:

jdbc:lohaco:SellerId=MySellerId;SSlClientCert=C:\private.pem;SSLClientCertType=PEMKEY_FILE;

Lohaco Data への接続性を持つJRuby アプリを作成

Create a new Ruby file (for example: LohacoSelect.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 Lohaco 2018/lib/cdata.jdbc.lohaco.jar' url = "jdbc:lohaco:SellerId=MySellerId;SSlClientCert=C:\private.pem;SSLClientCertType=PEMKEY_FILE;" conn = java.sql.DriverManager.getConnection(url) stmt = conn.createStatement rs = stmt.executeQuery("SELECT ItemCd, Price FROM Items") while (rs.next) do puts rs.getString(1) + ' ' + rs.getString(2) end

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

jruby -S LohacoSelect.rb

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