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 Oracle Sales Cloud を使用すると、JRuby からリアルタイムOracle Sales Cloud data へのデータ連携を簡単に実装できます。ここでは、Oracle Sales Cloud 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。
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 Oracle Sales Cloud\lib).
JRuby natively supports JDBC, so you can easily connect to Oracle Sales Cloud and execute SQL queries.Initialize the JDBC connection with the getConnection function of the java.sql.DriverManager class.
Oracle Sales Cloud はSSL 経由でBasic 認証を使用します。次の接続プロパティを設定して、接続してください。
For assistance in constructing the JDBC URL, use the connection string designer built into the Oracle Sales Cloud JDBC Driver.Either double-click the JAR file or execute the jar file from the command-line.
java -jar cdata.jdbc.oraclesalescloud.jar
Fill in the connection properties and copy the connection string to the clipboard.
Below is a typical JDBC connection string for Oracle Sales Cloud:
jdbc:oraclesalescloud:HostURL=https://my.host.oraclecloud.com; Username=abc123; Password=abcdef;
Create a new Ruby file (for example: OracleSalesCloudSelect.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 Oracle Sales Cloud 2018/lib/cdata.jdbc.oraclesalescloud.jar'
url = "jdbc:oraclesalescloud:HostURL=https://my.host.oraclecloud.com; Username=abc123; Password=abcdef;"
conn = java.sql.DriverManager.getConnection(url)
stmt = conn.createStatement
rs = stmt.executeQuery("SELECT OptyId, Name FROM Opportunities")
while (rs.next) do
puts rs.getString(1) + ' ' + rs.getString(2)
end
With the file completed, you are ready to display your Oracle Sales Cloud data with JRuby.To do so, simply run your file from the command line:
jruby -S OracleSalesCloudSelect.rb
