Connect to Sage 200 Data in Ruby

The CData ODBC Driver for Sage 200 makes it easy to integrate connectivity to live Sage 200 data in Ruby. This article shows how to create a simple Ruby app that connects to Sage 200 data, executes a query, and displays the results.

Create an ODBC Connection to Sage 200 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.

• Schema: Determines which Sage 200 edition you are connecting to. Specify either StandardUK or ProfessionalUK.
• Subscription Key: Provides access to the APIs that are used to establish a connection. You will first need to log into the Sage 200 API website and subscribe to the API edition that matches your account. You can do so here: https://developer.columbus.sage.com/docs/services/api/uk. Afterwards, the subscription key may be found in your profile after logging into Sage 200.

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 Sage 200 Data

Create a new Ruby file (for example: Sage200Select.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 Sage200 Source','','')

#execute a SELECT query and store the result set
resultSet = cnxn.execute("SELECT Id, Code FROM Banks WHERE Code = '12345'")

#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 Sage 200 data with Ruby. To do so, simply run your file from the command line:

ruby Sage200Select.rb
