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 Microsoft OneDrive を使用すると、JRuby からリアルタイムMicrosoft OneDrive data へのデータ連携を簡単に実装できます。ここでは、Microsoft OneDrive 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 Microsoft OneDrive\lib).
JRuby natively supports JDBC, so you can easily connect to Microsoft OneDrive and execute SQL queries.Initialize the JDBC connection with the getConnection function of the java.sql.DriverManager class.
OneDrive uses the OAuth authentication standard. To authenticate using OAuth, you will need to create an app to obtain the OAuthClientId, OAuthClientSecret, and CallbackURL connection properties. See the OAuth section of the Help documentation for an authentication guide.
For assistance in constructing the JDBC URL, use the connection string designer built into the Microsoft OneDrive JDBC Driver.Either double-click the JAR file or execute the jar file from the command-line.
java -jar cdata.jdbc.onedrive.jar
Fill in the connection properties and copy the connection string to the clipboard.
Below is a typical JDBC connection string for Microsoft OneDrive:
jdbc:onedrive:OAuthClientId=MyApplicationId;OAuthClientSecret=MySecretKey;OAuthCallbackURL=http://localhost:33333;InitiateOAuth=GETANDREFRESH
Create a new Ruby file (for example: OneDriveSelect.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 Microsoft OneDrive 2018/lib/cdata.jdbc.onedrive.jar'
url = "jdbc:onedrive:OAuthClientId=MyApplicationId;OAuthClientSecret=MySecretKey;OAuthCallbackURL=http://localhost:33333;InitiateOAuth=GETANDREFRESH"
conn = java.sql.DriverManager.getConnection(url)
stmt = conn.createStatement
rs = stmt.executeQuery("SELECT Id, Name FROM Files")
while (rs.next) do
puts rs.getString(1) + ' ' + rs.getString(2)
end
With the file completed, you are ready to display your Microsoft OneDrive data with JRuby.To do so, simply run your file from the command line:
jruby -S OneDriveSelect.rb
