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

I've used Montago's solution, but converted it to SQL code which did the job for me. Be free to use it, I hope it helps you :)

USE DatabaseName
GO

DECLARE @sqlDrop VARCHAR(1000)
SET @sqlDrop = 'IF EXISTS (SELECT * FROM #table# WHERE object_id = OBJECT_ID(''#name#'')) DROP #what# #name#'
DECLARE @sqlCommand VARCHAR(1000)

DECLARE @id INT
SET @id = 0
DECLARE @name SYSNAME
DECLARE @prev INT

WHILE 1 = 1
   BEGIN
      /* find traces of synchronization */

      -- to be sure that id changed
      SET @prev = @id

      -- get the next table
      SELECT TOP 1
             @id = object_id,
             @name = name
        FROM sys.tables
       WHERE object_id > @id
       ORDER BY object_id

      -- confirm that there is next table
      IF @id = @prev
         BREAK

      /* remove traces of synchronization */

      -- remove table
      SET @sqlCommand = @sqlDrop
      SET @sqlCommand = REPLACE(@sqlCommand, '#table#', 'sys.tables')
      SET @sqlCommand = REPLACE(@sqlCommand, '#name#', @name + '_tracking')
      SET @sqlCommand = REPLACE(@sqlCommand, '#what#', 'TABLE')
      EXEC (@sqlCommand)

      -- remove triggers
      SET @sqlCommand = @sqlDrop
      SET @sqlCommand = REPLACE(@sqlCommand, '#table#', 'sys.triggers')
      SET @sqlCommand = REPLACE(@sqlCommand, '#name#', @name + '_delete_trigger')
      SET @sqlCommand = REPLACE(@sqlCommand, '#what#', 'TRIGGER')
      EXEC (@sqlCommand)
      SET @sqlCommand = REPLACE(@sqlCommand, '_delete_trigger', '_insert_trigger')
      EXEC (@sqlCommand)
      SET @sqlCommand = REPLACE(@sqlCommand, '_insert_trigger', '_update_trigger')
      EXEC (@sqlCommand)

      -- remove stored procedures
      SET @sqlCommand = @sqlDrop
      SET @sqlCommand = REPLACE(@sqlCommand, '#table#', 'sys.procedures')
      SET @sqlCommand = REPLACE(@sqlCommand, '#name#', @name + '_delete')
      SET @sqlCommand = REPLACE(@sqlCommand, '#what#', 'PROCEDURE')
      EXEC (@sqlCommand)
      SET @sqlCommand = REPLACE(@sqlCommand, '_delete', '_deletemetadata')
      EXEC (@sqlCommand)
      SET @sqlCommand = REPLACE(@sqlCommand, '_deletemetadata', '_insert')
      EXEC (@sqlCommand)
      SET @sqlCommand = REPLACE(@sqlCommand, '_insert', '_insertmetadata')
      EXEC (@sqlCommand)
      SET @sqlCommand = REPLACE(@sqlCommand, '_insertmetadata', '_selectchanges')
      EXEC (@sqlCommand)
      SET @sqlCommand = REPLACE(@sqlCommand, '_selectchanges', '_selectrow')
      EXEC (@sqlCommand)
      SET @sqlCommand = REPLACE(@sqlCommand, '_selectrow', '_update')
      EXEC (@sqlCommand)
      SET @sqlCommand = REPLACE(@sqlCommand, '_update', '_updatemetadata')
      EXEC (@sqlCommand)
      SET @sqlCommand = REPLACE(@sqlCommand, '_updatemetadata', '_bulkdelete')
      EXEC (@sqlCommand)
      SET @sqlCommand = REPLACE(@sqlCommand, '_bulkdelete', '_bulkinsert')
      EXEC (@sqlCommand)
      SET @sqlCommand = REPLACE(@sqlCommand, '_bulkinsert', '_bulkupdate')
      EXEC (@sqlCommand)

   END

-- remove scope and schema tables
SET @sqlCommand = @sqlDrop
SET @sqlCommand = REPLACE(@sqlCommand, '#table#', 'sys.tables')
SET @sqlCommand = REPLACE(@sqlCommand, '#name#', 'schema_info')
SET @sqlCommand = REPLACE(@sqlCommand, '#what#', 'TABLE')
EXEC (@sqlCommand)
SET @sqlCommand = REPLACE(@sqlCommand, 'schema_info', 'scope_config')
EXEC (@sqlCommand)
SET @sqlCommand = REPLACE(@sqlCommand, 'scope_config', 'scope_info')
EXEC (@sqlCommand)

This, as you can see goes through all the tables and try to find traces of syncing. You just need to change the database name (first line). Also, if you want to be safer with what you delete, use this code to find tables:

  -- get the next table
  SELECT TOP 1
         @id = object_id,
         @name = REPLACE(name, '_tracking', '')
    FROM sys.tables
   WHERE object_id > @id
     AND name LIKE '%_tracking'
   ORDER BY object_id

This will only look for tables that are actually being synchronized
