Connect to Sybase IQ Data in Ruby
Connect to Sybase IQ data in Ruby with ruby-dbi, dbd-odbc, and ruby-odbc.
The CData ODBC Driver for Sybase IQ makes it easy to integrate connectivity to live Sybase IQ data in Ruby. This article shows how to create a simple Ruby app that connects to Sybase IQ data, executes a query, and displays the results.
Create an ODBC Connection to Sybase IQ 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 SybaseIQ, set User, Password, Server and Database properties. To secure connections with TLS/SSL, set UseSSL to TRUE.
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 Sybase IQ Data
Create a new Ruby file (for example: SybaseIQSelect.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 SybaseIQ Source','','')
#execute a SELECT query and store the result set
resultSet = cnxn.execute("SELECT ProductName, Price FROM Products WHERE ProductName = 'Konbu'")
#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 Sybase IQ data with Ruby. To do so, simply run your file from the command line:
ruby SybaseIQSelect.rb
Writing SQL-92 queries to Sybase IQ allows you to quickly and easily incorporate Sybase IQ data into your own Ruby applications. Download a free trial today!
