TigerGraph Icon TigerGraph ODBC Driver

The TigerGraph ODBC Driver is a powerful tool that allows you to connect with live data from TigerGraph, directly from any applications that support ODBC connectivity.

Access TigerGraph data like you would a relational database through a standard ODBC Driver interface.

Connect to TigerGraph Data in Ruby

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

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

Create an ODBC Connection to TigerGraph 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 authenticate with your TigerGraph instance, set the User, Password, and URL properties to valid TigerGraph credentials. By default connections are made on port 14240.

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 TigerGraph Data

Create a new Ruby file (for example: TigerGraphSelect.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 TigerGraph Source','','') #execute a SELECT query and store the result set resultSet = cnxn.execute("SELECT id, locationId FROM person WHERE locationId = 'chn'") #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 TigerGraph data with Ruby. To do so, simply run your file from the command line:

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