Question

我已经设置了与Microsoft Sync Framework的同步，现在我需要向表中添加字段。如何重新配置数据库？

设置非常简单：

两台SQL Express 2008服务器
范围包括整个数据库
使用Microsoft Sync Framework 2.0
通过直接访问进行同步。使用标准新SqlSyncProvider

我是否在两端进行结构改变？或者我只更改一台服务器并让Sync Framework以某种方式传播更改？

我是否需要删除_tracking表和/或存储过程？触发器怎么样？

有没有人使用过Sync Framework？请帮忙。

Answer 1

实际上，我在我的博客上发布了自己的答案http://myazurejourney.blogspot.com/

它有一些步骤，它绝对是一个黑客。但它确实有效。

检查出来。告诉我你的想法

删除范围并重新提供...使用此代码删除范围

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'))

        dropTracking.ExecuteNonQuery();

        SqlCommand dropTriggers = new SqlCommand(@"

我使用过Montago的解决方案，但是将其转换为SQL代码，它为我完成了这项工作。可以自由使用它，我希望它可以帮助你：）

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)

正如您所看到的那样，遍历所有表并尝试查找同步的痕迹。您只需要更改数据库名称（第一行）。此外，如果您希望删除的内容更安全，请使用此代码查找表格：

  -- 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

这只会查找实际正在同步的表

您可以使用此脚本：

declare @SQL varchar(max);
set @SQL='';
select @SQL += ' IF EXISTS (SELECT * FROM sys.objects WHERE object_id = OBJECT_ID(N''[dbo].[schema_info]'') AND type in (N''U'')) ' +  
               ' DROP TABLE [dbo].[schema_info]; ' +
               ' IF EXISTS (SELECT * FROM sys.objects WHERE object_id = OBJECT_ID(N''[dbo].[scope_config]'') AND type in (N''U'')) ' + 
               ' DROP TABLE [dbo].[scope_config]; ' +
               ' IF EXISTS (SELECT * FROM sys.objects WHERE object_id = OBJECT_ID(N''[dbo].[scope_info]'') AND type in (N''U'')) ' +
