Recently I need to insert 400+ rows of data into an eight year old MSSQL 2000 and MSSQL 2008 database. It’s really a pain in the ass if I have to do it by hand or learning a new tool to do it. Luckily, I can use ActiveRecord to do that easily thanks to activerecord-sqlserver-adapter and and auto table field mapping of ActiveRecord.
Here is a quick step-by-step guide:
Install Ruby on Windows machine (that run SQL server). Download One-Click Ruby Installer for Windows for Ruby 1.8.6 P26 at
And install it. If you use the default setting, it will setup ruby at c:ruby folder with rubygem 0.9.3
Open “Command Prompt”
cd c:rubybin gem update –system
Install ActiveRecord with SQLServer Adapter
gem install activerecord-sqlserver-adapter –source=http://gems.rubyonrails.org
If the installation result is:
Successfully installed activesupport-2.2.2 Successfully installed activerecord-2.2.2 Successfully installed activerecord-sqlserver-adapter-22.214.171.12450 3 gems installed
Create a DSN (Data Source Name) Luckily I can reuse DNS from current ASP project so I don’t need to create new one. If you have to, you can follow guideline in .
Setup connection and create property ActiveRecord based classes
:adapter => “sqlserver”,
:mode => “odbc”,
:username => “yourusername”,
:password => “yourpassword”,
:dsn => “yourDSN”
class AnyNameYouWant < ActiveRecord::Base
Start irb by:
cd c:rubybin irb
And paste above chuck of code in to irb. From now, you can use ActiveRecord based classes to read/write/add/remove SQL Server table as in a Rails script/console environment.
I also got a problem with Time.mktime and need to some code adjust by hand
Replace “Time.mktime” by “Datetime.new” will fix the problem
