Microsoft Sync Framework - How to reprovision a table (or entire scope) after schema changes?

Question

I have already setup syncing with Microsoft Sync Framework, and now I need to add fields to a table. How do I re-provision the databases?

The setup is exceedingly simple:

• Two SQL Express 2008 servers
• The scope includes the entire database
• Using Microsoft Sync Framework 2.0
• Synchronizing by direct access. Using the standard new SqlSyncProvider

Do I make the structural changes at both ends? Or do I only change one server and let Sync Framework somehow propagate the change?

Do I need to delete the _tracking tables and/or the stored procedures? How about the triggers?

Has anyone been using the Sync Framework? Please help.

Actually, I posted my own answer on my blog http://myazurejourney.blogspot.com/

It has a few step, and it's definitely a hack. But it works.

remove the scope and re-provision... use this code to remove a scope

private void RemoveScope(SqlConnection Conn, bool ShowAlert)
{
    foreach (var table in _settings.TablesToSync)
    {
        SqlCommand dropTracking = new SqlCommand(@"
            IF  EXISTS (SELECT * FROM sys.objects WHERE object_id = OBJECT_ID(N'[dbo].[" + table.Key + @"_tracking]') AND type in (N'U'))
            DROP TABLE [dbo].[" + table.Key + "_tracking]", Conn);
        dropTracking.ExecuteNonQuery();

        SqlCommand dropTriggers = new SqlCommand(@"
            IF  EXISTS (SELECT * FROM sys.triggers WHERE object_id = OBJECT_ID(N'[dbo].[" + table.Key + @"_delete_trigger]'))
            DROP TRIGGER [dbo].[" + table.Key + @"_delete_trigger];

            IF  EXISTS (SELECT * FROM sys.triggers WHERE object_id = OBJECT_ID(N'[dbo].[" + table.Key + @"_insert_trigger]'))
            DROP TRIGGER [dbo].[" + table.Key + @"_insert_trigger];

            IF  EXISTS (SELECT * FROM sys.triggers WHERE object_id = OBJECT_ID(N'[dbo].[" + table.Key + @"_update_trigger]'))
            DROP TRIGGER [dbo].[" + table.Key + @"_update_trigger];
        ", Conn);
        dropTriggers.ExecuteNonQuery();

        SqlCommand dropStoredProc = new SqlCommand(@"
            IF  EXISTS (SELECT * FROM sys.objects WHERE object_id = OBJECT_ID(N'[dbo].[" + table.Key + @"_delete]') AND type in (N'P', N'PC'))
            DROP PROCEDURE [dbo].[" + table.Key + @"_delete];

            IF  EXISTS (SELECT * FROM sys.objects WHERE object_id = OBJECT_ID(N'[dbo].[" + table.Key + @"_deletemetadata]') AND type in (N'P', N'PC'))
            DROP PROCEDURE [dbo].[" + table.Key + @"_deletemetadata];

            IF  EXISTS (SELECT * FROM sys.objects WHERE object_id = OBJECT_ID(N'[dbo].[" + table.Key + @"_insert]') AND type in (N'P', N'PC'))
            DROP PROCEDURE [dbo].[" + table.Key + @"_insert];

            IF  EXISTS (SELECT * FROM sys.objects WHERE object_id = OBJECT_ID(N'[dbo].[" + table.Key + @"_insertmetadata]') AND type in (N'P', N'PC'))
            DROP PROCEDURE [dbo].[" + table.Key + @"_insertmetadata];

            IF  EXISTS (SELECT * FROM sys.objects WHERE object_id = OBJECT_ID(N'[dbo].[" + table.Key + @"_selectchanges]') AND type in (N'P', N'PC'))
            DROP PROCEDURE [dbo].[" + table.Key + @"_selectchanges];

            IF  EXISTS (SELECT * FROM sys.objects WHERE object_id = OBJECT_ID(N'[dbo].[" + table.Key + @"_selectrow]') AND type in (N'P', N'PC'))
            DROP PROCEDURE [dbo].[" + table.Key + @"_selectrow];

            IF  EXISTS (SELECT * FROM sys.objects WHERE object_id = OBJECT_ID(N'[dbo].[" + table.Key + @"_update]') AND type in (N'P', N'PC'))
            DROP PROCEDURE [dbo].[" + table.Key + @"_update];

            IF  EXISTS (SELECT * FROM sys.objects WHERE object_id = OBJECT_ID(N'[dbo].[" + table.Key + @"_updatemetadata]') AND type in (N'P', N'PC'))
            DROP PROCEDURE [dbo].[" + table.Key + @"_updatemetadata];
        ", Conn);
        dropStoredProc.ExecuteNonQuery();
    }

    SqlCommand getScopeGuid = new SqlCommand(@"
            USE [" + Conn.Database + @"]
            SELECT scope_config_id FROM scope_info WHERE scope_name = '" + _settings.ScopeName + "'", Conn);

    var reader = getScopeGuid.ExecuteReader();

    if (reader.HasRows)
    {
        reader.Read();

        var id = reader.GetGuid(0);

        reader.Close();

        SqlCommand deleteScope = new SqlCommand(@"
                DELETE FROM scope_info WHERE scope_config_id = '" + id + @"';
                DELETE FROM scope_config WHERE config_id = '" + id + @"';
            ", Conn);
        deleteScope.ExecuteNonQuery();
    }

    if(ShowAlert)
        MessageBox.Show("Scope has been removed");
}
