Question

I’m new to TFS and needing to write a TSQL query to get a listing of all files and version numbers that were included in a particular changeset version number. While searching online for the tables to get this information I found some people mentioning to use the Tfs_Warehouse database and others that used the Tfs_DefaultCollection database. I have the following questions:

• What is the difference between the two databases?
• Why would you use one instead of the other?
• Which tables do you use to obtain the file/version information for a particular changeset?

Answer 1

You can use the VersionControlServer.GetChangeset() method from the TFS Object Model.

You will need to add references to the following assemblies in the GAC:

• Microsoft.TeamFoundation.Common
• Microsoft.TeamFoundation.Client

• Microsoft.TeamFoundation.VersionControl.Client

  Private Shared Sub Main(ByVal args As String())
      Dim tfs As TfsTeamProjectCollection = TfsTeamProjectCollectionFactory.GetTeamProjectCollection(New Uri("http://tfsserver:8080/tfs/CollectionName"), New UICredentialsProvider)
      tfs.Connect(ConnectOptions.None)
      Dim vcs As VersionControlServer = tfs.GetService(Of VersionControlServer)
      Dim changeset As Changeset = vcs.GetChangeset(changeset ID, True, False)
  End Sub
  

Then you can inspect the .Changes property to see all the changes included in the Changeset.
