Connect to SAP HANA Data in Ruby


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

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

Create an ODBC Connection to SAP HANA 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.

Set the Server, Database and Port properties to specify the address of your SAP Hana database to interact with. Set the User and the Password properties to authenticate to the server.

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 SAP HANA Data

Create a new Ruby file (for example: SAPHANASelect.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 SAPHANA Source','','') #execute a SELECT query and store the result set resultSet = cnxn.execute("SELECT Name, OwnerId FROM Buckets WHERE Name = 'TestBucket'") #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 SAP HANA data with Ruby. To do so, simply run your file from the command line:

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