Connect to SendInBlue Data in JRuby

JRuby is a high-performance, stable, fully threaded Java implementation of the Ruby programming language. The CData JDBC Driver for SendInBlue makes it easy to integrate connectivity to live SendInBlue data in JRuby. This article shows how to create a simple JRuby app that connects to SendInBlue data, executes a query, and displays the results.

Configure a JDBC Connection to SendInBlue 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 SendInBlue\lib).

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

Start by setting the Profile connection property to the location of the SendInBlue Profile on disk (e.g. C:\profiles\SendInBlue.apip). Next, set the ProfileSettings connection property to the connection string for SendInBlue (see below).

SendInBlue API Profile Settings

In your SendInBlue account, click your username in the top right, select SMTP & API, and copy your API key from that page.

Built-in Connection String Designer

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

java -jar cdata.jdbc.api.jar

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

Below is a typical JDBC connection string for SendInBlue:

jdbc:api:Profile=C:\profiles\SendInBlue.apip;ProfileSettings='APIKey=your_api_key';

Create a JRuby App with Connectivity to SendInBlue Data

Create a new Ruby file (for example: APISelect.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 SendInBlue 2018/lib/cdata.jdbc.api.jar'

url = "jdbc:api:Profile=C:\profiles\SendInBlue.apip;ProfileSettings='APIKey=your_api_key';"
conn = java.sql.DriverManager.getConnection(url)
stmt = conn.createStatement
rs = stmt.executeQuery("SELECT Email, FirstName FROM Account")
while (rs.next) do
  puts rs.getString(1) + ' ' + rs.getString(2)
end

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

jruby -S APISelect.rb
