Connect to SendGrid Data in Ruby

Connect to SendGrid data in Ruby with ruby-dbi, dbd-odbc, and ruby-odbc.

The CData ODBC Driver for SendGrid makes it easy to integrate connectivity to live SendGrid data in Ruby. This article shows how to create a simple Ruby app that connects to SendGrid data, executes a query, and displays the results.

Create an ODBC Connection to SendGrid Data

If you have not already, first specify connection properties in an ODBC DSN (data source name). This is the last step of the driver installation. You can use the Microsoft ODBC Data Source Administrator to create and configure ODBC DSNs.

To make use of all the available features, provide the User and Password connection properties.

To connect with limited features, you can set the APIKey connection property instead. See the "Getting Started" chapter of the help documentation for a guide to obtaining the API key.

Installing Ruby and Necessary Gems

If you do not have Ruby installed, refer to the Ruby installation page. With Ruby installed, you will need to install the ruby-dbi, dbd-odbc, and ruby-odbc gems:

gem install dbi gem install dbd-odbc gem install ruby-odbc

Create a Ruby App with Connectivity to SendGrid Data

Create a new Ruby file (for example: SendGridSelect.rb) and open it in a text editor. Copy the following code into your file:

#connect to the DSN require 'DBI' cnxn = DBI.connect('DBI:ODBC:CData SendGrid Source','','') #execute a SELECT query and store the result set resultSet = cnxn.execute("SELECT Name, Clicks FROM AdvancedStats") #display the names of the columns resultSet.column_names.each do |name| print name, "\t" end puts #display the results while row = resultSet.fetch do (0..resultSet.column_names.size - 1).each do |n| print row[n], "\t" end puts end resultSet.finish #close the connection cnxn.disconnect if cnxn

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

ruby SendGridSelect.rb Writing SQL-92 queries to SendGrid allows you to quickly and easily incorporate SendGrid data into your own Ruby applications. Download a free trial today!
