Ruby Scripts - Simple SQL dumps

We have an old version of SQL GUI tool that can return the results of an SQL statement as tab delimited data. This works fine for small result sets. However I created a Reconciliation system that needed few 10's of thousands of records. The GUI just could not handle that. So, a nice exercise to use Ruby to the rescue and learn more about it's DBI.

Here is the sample Ruby code:
require 'DBI'

# make an ODBC connection
conn = DBI.connect('DBI:ODBC:','[USERNAME-HERE]','[PASSWORD-HERE]')

sth = conn.execute("
[SELECT STATEMENT HERE]
")
# If you need column names, then you can use the below statement to get them
# cols=sth.column_names
sth.each do |row|
puts = row.join("\t")
end
sth.finish

Nothing except the Ruby Installer was needed to run this.
