Connect to Azure Analysis Services Data in Ruby
Connect to Azure Analysis Services data in Ruby with ruby-dbi, dbd-odbc, and ruby-odbc.
The CData ODBC Driver for Azure Analysis Services makes it easy to integrate connectivity to live Azure Analysis Services data in Ruby. This article shows how to create a simple Ruby app that connects to Azure Analysis Services data, executes a query, and displays the results.
Create an ODBC Connection to Azure Analysis Services 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 Azure Analysis Services, set the Url property to a valid server, for instance, asazure://southcentralus.asazure.windows.net/server, in addition to authenticating. Optionally, set Database to distinguish which Azure database on the server to connect to.
Azure Analysis Services uses the OAuth authentication standard. OAuth requires the authenticating user to interact with Azure Analysis Services using the browser. You can connect without setting any connection properties for your user credentials. See the Help 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 Azure Analysis Services Data
Create a new Ruby file (for example: AASSelect.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 AAS Source','','')
#execute a SELECT query and store the result set
resultSet = cnxn.execute("SELECT Country, Education FROM Customer WHERE Country = 'Australia'")
#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 Azure Analysis Services data with Ruby. To do so, simply run your file from the command line:
ruby AASSelect.rb
