Project RoundhousE - Database Change Management done right

RoundhousE - Professional Database Management


Apache 2.0 - see docs\legal (just LEGAL in the zip folder)




NOTE: If you are looking at the source - please run build.bat before opening the solution. It creates the SolutionVersion.cs file that is necessary for a successful build.



RoundhousE is an automated database deployment (change management) system that allows you to use your current idioms and gain much more. Currently it only supports Microsoft SQL Server, but there are future plans for other databases.

It seeks to solve both maintenance concerns and ease of deployment. We follow some of the same idioms as other database management systems (SQL scripts), but we are different in that we think about future maintenance concerns. We want to always apply certain scripts (anything stateless like functions, views, stored procedures, and permissions), so we don't have to throw everything into our change scripts. This seeks to solves future source control concerns. How sweet is it when you can version the database according to your current source control version?

Getting started with RoundhousE


You can download RoundhousE from

You can also obtain a copy from the build server at


If you have Ruby 1.8.6+ (and Gems 1.3.7+) installed, you can get the current release of RoundhousE to your machine quickly!

  1. Type gem install roundhouse
  2. Then from anywhere you can type rh [options]


With NuGet you can get the current release of RoundhousE to your application quickly!

  1. In Visual Studio Package Manager Console type install-package roundhouse
  2. There is also roundhouse.lib, roundhouse.msbuild, and roundhouse.refreshdatabase


Chocolatey like apt-get, but for Windows! This is an alternative method to get the current release of RoundhousE to your machine quickly!

  1. Type cinst roundhouse
  2. Then from anywhere you can type rh [options]


This is the best way to get to the bleeding edge of what we are doing.

  1. Clone the source down to your machine.
    git clone git://
  2. Type cd roundhouse
  3. Type git config core.autocrlf false to leave line endings as they are.
  4. Type git status. You should not see any files to change.
  5. Run build.bat. NOTE: You must have git on the path (open a regular command line and type git).


  • .NET Framework 3.5
  • SA access to the sql server (for creation or deletion)
  • change access to the database (for everything else)

  • FIX: Fixed a nasty bug with SQL Server where it tries to hold a connection (interferes with drop/create mode) and gives a transport error (r331)
  • Custom Scripts also run token replacement (r321, r330)

  • FIX: Migrate doesn't try to configure log4net now (causes issues w/libraries that do) (r326)
  • Two new folders available: Indexes and AlterDatabase (r324)
  • FIX: Included sample for Oracle doesn't work. See [issue 55] ( for details. (r322)
  • RH now works with MySQL. Thanks Diyan. See details (r317)



  • Fixed a few issues with using the connection string. You should now be able to only supply the connection string and not server/database as well.


  • Fixed a collation issue with RoundhousE id columns in its tracking tables. See [issue 46] ( for details. (r274)
  • RestoreFromPath can take a relative path. (r269)
  • RH can now upgrade it's internals without user interaction. See [issue 40] ( for details. (r268)
  • MSBuild / NAnt tasks are deprecated and no longer hooked up. Please use the console and call it from your tasks. (r268)
  • RH has differencing support with NHibernate Schema Generation/Updates (r267 - branch, r268)
  • FluentNhibernate and NHibernate are now being used for the internals (r267 - branch, r268)
  • SMO is deprecated and removed (r203 - branch, r268)
  • Gems and build upgrades, oh my! (r259)
  • SQL2000 to 2005 is now a smooth transition. (r221)

  • Fix: Uppercase User names when running with Oracle. (r200)
  • RH has differencing support with RedGate. See sample project for details. (r197)
  • Fix: Scrips run errors now updates version number and path w/out a dependency on scripts run. Allows for it to finish during transactional runs and still capture errors. (r196)
  • Fix: Capture errortastic changes to DDL/DML (up) files in the script run errors table. (r191)
  • Added admin connection string to do administrative tasks. (r190)


  • RH handles nonsupported DDL transactions. RH will also stop and inform the user when DDL transactions are not supported, so user can choose to continue - see issue 28 for details. (r172 - branch, r185)
  • RH logs when errors occur in the RoundhousE.ScriptRunErrors table - see issue 28 for details. (r167 - branch, r185)

  • RH has an icon of the logo (r99)


  • OleDB Support - RH can now be run for advanced database connections with a connection string. (r96)
    • OleDB may not support creating/restoring/deleting databases.
    • Microsoft Access is supported through OleDB.
    • Other databases will need to have scripts written for their type before they would be supported.


  • Environment awareness - RH determines an environment file first that it has ".ENV." in the file name and then if it is the proper environment file based on whether the file also contains the specific environment name. For example LOCAL.0001_DoSomething.ENV.sql will run in the LOCAL environment but no where else.
