JRuby からTally Data にデータ連携

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

Tally 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 Tally\lib).

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

Set the following connection properties to connect to Tally Instance:

  • Url: Set this to the URL for your Tally instance. For example: http://localhost:9000.

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

java -jar cdata.jdbc.tally.jar

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

Below is a typical JDBC connection string for Tally:

jdbc:tally:Url='http://localhost:9000'

Tally Data への接続性を持つJRuby アプリを作成

Create a new Ruby file (for example: TallySelect.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 Tally 2018/lib/cdata.jdbc.tally.jar' url = "jdbc:tally:Url='http://localhost:9000'" conn = java.sql.DriverManager.getConnection(url) stmt = conn.createStatement rs = stmt.executeQuery("SELECT Name, Address FROM Company") while (rs.next) do puts rs.getString(1) + ' ' + rs.getString(2) end

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

jruby -S TallySelect.rb

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