Connect to JDBC-ODBC Bridge Data in JRuby
Create a simple JRuby app with access to live JDBC-ODBC Bridge data.
JRuby is a high-performance, stable, fully threaded Java implementation of the Ruby programming language. The CData JDBC Driver for JDBC-ODBC Bridge makes it easy to integrate connectivity to live JDBC-ODBC Bridge data in JRuby. This article shows how to create a simple JRuby app that connects to JDBC-ODBC Bridge data, executes a query, and displays the results.
Configure a JDBC Connection to JDBC-ODBC Bridge Data
Before creating the app, note the installation location for the JAR file for the JDBC Driver (typically C:\Program Files\CData\CData JDBC Driver for JDBC-ODBC Bridge\lib).
JRuby natively supports JDBC, so you can easily connect to JDBC-ODBC Bridge and execute SQL queries. Initialize the JDBC connection with the getConnection function of the java.sql.DriverManager class.
To connect to an ODBC data source, specify either the DSN (data source name) or specify an ODBC connection string: Set Driver and the connection properties for your ODBC driver.Built-in Connection String Designer
For assistance in constructing the JDBC URL, use the connection string designer built into the JDBC-ODBC Bridge JDBC Driver. Either double-click the JAR file or execute the jar file from the command-line.
java -jar cdata.jdbc.jdbcodbc.jar
Fill in the connection properties and copy the connection string to the clipboard.
Below is a typical JDBC connection string for JDBC-ODBC Bridge:
jdbc:jdbcodbc:Driver={ODBC_Driver_Name};Driver_Property1=Driver_Value1;Driver_Property2=Driver_Value2;...
Create a JRuby App with Connectivity to JDBC-ODBC Bridge Data
Create a new Ruby file (for example: JDBCODBCSelect.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 JDBC-ODBC Bridge 2018/lib/cdata.jdbc.jdbcodbc.jar'
url = "jdbc:jdbcodbc:Driver={ODBC_Driver_Name};Driver_Property1=Driver_Value1;Driver_Property2=Driver_Value2;..."
conn = java.sql.DriverManager.getConnection(url)
stmt = conn.createStatement
rs = stmt.executeQuery("SELECT Id, Name FROM Account")
while (rs.next) do
puts rs.getString(1) + ' ' + rs.getString(2)
end
With the file completed, you are ready to display your JDBC-ODBC Bridge data with JRuby. To do so, simply run your file from the command line:
jruby -S JDBCODBCSelect.rb
