Create an ODBC Connection to SAP HANA XS Advanced 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.

gem install dbi gem install dbd-odbc gem install ruby-odbc

Create a Ruby App with Connectivity to SAP HANA XS Advanced Data

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