Wordpress ODBC Driver

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

Access Wordpress data like you would a database - read, write, and update Wordpress Pages, Posts, Tags, Users, etc. through a standard ODBC Driver interface.



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

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

Create an ODBC Connection to WordPress 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 connect to WordPress, set the URL property and other authentication properties. WordPress supports Basic (User and Password) and OAuth2.0 authentication, though Basic is recommended for a testing environment only. To connect with OAuth you will need to register an app with WordPress.

See the Getting Started guide in the CData driver documentation for more information.

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 WordPress Data

Create a new Ruby file (for example: WordPressSelect.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 WordPress Source','','') #execute a SELECT query and store the result set resultSet = cnxn.execute("SELECT Id, Name FROM Categories") #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 WordPress data with Ruby. To do so, simply run your file from the command line:
